Description

동축 도파관 공간결합기를 이용한 고출력 전력 증폭기High Output Power Amplifier Using Coaxial Waveguide Spatial Coupler

본 발명은 고출력 전력 증폭기에 관한 것으로서, 보다 상세하게는 동축 도파관 공간결합기를 이용한 고출력 전력 증폭기에 관한 것이다. The present invention relates to a high output power amplifier, and more particularly to a high output power amplifier using a coaxial waveguide spatial coupler.

1960년대 Wilkinson에 의해 처음으로 하나의 입력신호가 두 개의 동일한 위상과 크기를 갖는 전력 분배기 및 전력 결합기가 개발된 이후 현재 시스템에는 분배기 및 결합기, branch-line 커플러, Lange 커플러, rat-race 커플러 등과 같은 다양한 구조의 전력 분배기 및 전력 결합기가 적용되어 사용되고 있다.In the 1960s, after Wilkinson first developed power dividers and power combiners in which one input signal had two identical phases and magnitudes, current systems include dividers and couplers, branch-line couplers, Lange couplers, rat-race couplers, etc. Various types of power dividers and power combiners have been applied and used.

전력 결합기는 평면결합방식과 공간결합방식으로 구분될 수 있고, 평면결합방식은 PCB(인쇄회로기판)상에 회로패턴 또는 케이블을 이용하여 전자기 에너지를 결합하는 방법이다. The power combiner can be classified into a planar coupling method and a space coupling method. The planar coupling method is a method of combining electromagnetic energy using a circuit pattern or a cable on a printed circuit board (PCB).

평면결합방식은 이론적으로 N-way 결합(N은 2 이상의 자연수임)이 가능하지만 결합하고자 하는 전력소자의 개수가 늘어날수록 이를 분배 및 결합하기 위한 마이크로스트립 라인(microstrip line)의 길이가 늘어나 손실 및 복잡도가 증가하고 크기가 커져서 고출력, 고효율의 전력 증폭기에는 활용되기 힘들다는 단점이 있다. Planar coupling is theoretically possible for N-way coupling (N is a natural number of 2 or more), but as the number of power devices to be coupled increases, the length of the microstrip line for distributing and coupling them increases, causing loss and The increased complexity and increased size make it difficult to utilize in high-power, high-efficiency power amplifiers.

반면 공간결합방식의 전력 결합기는 평면 결합 방식에 비해 결합되는 전력 소자의 개수가 증가여도 손실이 이에 비례하여 증가하지 않는 장점이 있으므로 고출력, 고효율의 전력 증폭기에 활용되고 있다. On the other hand, the space-coupled power combiner is used in high-power, high-efficiency power amplifiers because the loss does not increase proportionally even if the number of power elements coupled is increased compared to the planar coupling method.

공간결합방식은 grid 증폭기와 같이 자유 공간에서 전력이 결합되는 방식과 도파관(Waveguide) 내에서 전력이 결합되는 방식으로 구분될 수 있다. The spatial coupling method can be divided into a method of combining power in free space, such as a grid amplifier, and a method of combining power in a waveguide.

자유 공간에서 전력이 결합되는 방식은 spill-over 손실이 존재하고 방열 특성이 좋지 않아 결합 효율이 떨어지는 단점이 있는 반면 도파관 내에서의 전력 결합 방식은 도파관 금속 자체가 좋은 방열판 역할을 할 수 있어 결합 효율이 좋다는 장점이 있다. The power coupling method in the free space has a disadvantage of poor coupling efficiency due to the presence of spill-over loss and poor heat dissipation characteristics, whereas the power coupling method in the waveguide can provide a good heat sink for the waveguide metal itself. This has the advantage of being good.

공간결합방식은 도파관의 종류에 따라 직사각형 도파관(Rectangular waveguide)을 이용한 공간전력결합방식과 동축도파관(Coaxial waveguide)을 이용한 공간전력결합방식으로 구분된다. The spatial coupling method is classified into a spatial power coupling method using a rectangular waveguide and a spatial power coupling method using a coaxial waveguide according to the waveguide type.

직사각형 도파관을 이용한 공간전력결합방식에서 반도체 소자를 이용하여 전력을 결합할 경우, 도파관의 가장자리에 위치한 안테나에 삽입된 전력 증폭기들이 포화전력에 도달했을 때 중앙에 위치한 증폭기는 이미 과구동되어 선형성이 저하되는 문제점이 있다. 이러한 문제점을 보완하기 위해서 도파관 양쪽에 유전체를 삽입하여 필드의 분포를 균일하게 해주는 방법이 연구되었으나 근본적인 해결책이 될 수 없었다. In case of combining power using semiconductor device in the spatial power coupling method using rectangular waveguide, when the power amplifiers inserted in the antenna located at the edge of the waveguide reach saturation power, the centrally located amplifier is already overdriven and linearity deteriorates. There is a problem. To solve this problem, a method of equalizing the field distribution by inserting dielectrics on both sides of the waveguide has been studied, but it cannot be a fundamental solution.

한편, 동축도파관(Coaxial waveguide)을 이용한 공간전력결합방식은 직사각형 도파관처럼 단일 금속관으로 이루어져 있지 않고 중앙에 있는 도체(Inner conductor)와 바깥쪽의 도체주위를 싸고 있는 원기둥 도체(Outer Conductor)로 이루어져 있다. Meanwhile, the spatial power coupling method using a coaxial waveguide is not composed of a single metal tube like a rectangular waveguide but consists of an inner conductor in the center and an outer conductor surrounding the outer conductor. .

동축도파관을 이용한 공간결합기는 전자기파의 진행방향에 대해서 전계분포와 자계분포 모두 수직의 형태로 구성되는 TEM모드(Transverse Electro Magnetic field)가 이용되는데, TEM모드는 신호의 흐름을 억제하는 차단 주파수가 없기 때문에 광대역 특성을 얻을 수 있다. 따라서, 고출력시스템에 적용될 수 있는 현실적이고도 활용도가 높은 동축도파관을 이용한 공간결합기 기술이 절실히 요구되는 실정이다.The spatial coupler using the coaxial waveguide uses a TEM mode (Transverse Electro Magnetic field) in which both the electric field distribution and the magnetic field distribution are perpendicular to the traveling direction of the electromagnetic wave. The TEM mode does not have a cutoff frequency that suppresses signal flow. Therefore, broadband characteristics can be obtained. Therefore, there is an urgent need for a spatial coupler technology using a coaxial waveguide which is realistic and highly applicable to a high power system.

본 발명이 이루고자 하는 기술적 과제는 고출력 시스템에 적용될 수 있는 동축 도파관 공간결합기를 이용한 고출력 전력 증폭기를 제공하는 것이다. The present invention is to provide a high output power amplifier using a coaxial waveguide spatial coupler that can be applied to a high output system.

또한, 본 발명이 이루고자 하는 기술적 과제는 안정적인 전원공급이 가능한 동축 도파관 공간결합기를 이용한 고출력 전력 증폭기를 제공하는 것이다.In addition, the technical problem to be achieved by the present invention is to provide a high output power amplifier using a coaxial waveguide spatial coupler capable of a stable power supply.

또한, 본 발명이 이루고자 하는 기술적 과제는 공간결합기를 원형으로 설계하여 일률적인 손실 및 위상값을 얻을 수 있는 동축 도파관 공간결합기를 이용한 고출력 전력 증폭기를 제공하는 것이다.In addition, the technical problem to be achieved by the present invention is to provide a high output power amplifier using a coaxial waveguide spatial coupler that can obtain a uniform loss and phase value by designing a space coupler in a circular shape.

The spatial power divider 110 may generate n distributed signals by distributing an input signal (hereinafter, referred to as an “input signal”). The spatial power divider 110 distributes the input signals at a predetermined ratio determined by the number (n) of the amplifiers 120-1, 120-2, ..., 120-n to generate n distributed signals. Can be. The generated n distribution signals may be transmitted to the corresponding amplifiers 120-1, 120-2, ..., 120-n, respectively. The space power divider 110 according to the embodiment of the present invention may be a coaxial waveguide space power divider. Therefore, the space power divider 110 may output an input signal to the space in the waveguide, and the input signal output to the space in the waveguide is output as n distribution signals by each of n tapered pin lines (see FIG. 2) in the waveguide. Can be. Each of the n distributed signals is provided with corresponding n power amplifiers 120-1, 120-2, ... 120-n through corresponding output cables 140-1, 140-2, ... 140-n. Can be entered.

In addition, each of the n power amplifiers 120-1, 120-2,..., 120-n may receive a distribution signal from the space power divider 110 and amplify and output the distributed signal. For example, the first power amplifier 120-1 may receive and amplify the first divided signal input from the first output port of the spatial power divider 110. In addition, the second power amplifier 120-2 may receive the amplified second distribution signal input from the second output port of the space power divider 110 and output the amplified signal. In addition, the n-th power amplifier 120-n may receive an n-th distribution signal input from the n-th output port of the spatial power divider 110 and amplify and output the n-th distribution signal.

공간전력결합기(130)는 n개의 전력증폭기(120-1, 120-2, ... 120-n) 각각으로부터 증폭된 분배신호를 입력받아 단일의 증폭신호로 결합하여 출력할 수 있다. 본 발명의 실시예에 따른 공간전력결합기(130)는 동축 도파관 공간전력결합기일 수 있다. 따라서 공간전력결합기(130)는 n개의 전력증폭기(120-1, 120-2, ... 120-n) 각각으로부터 입력된 증폭된 분배신호가 도파관 내의 n개의 테이퍼 핀라인(도2 참조) 각각에 의하여 도파관 내의 공간으로 출력될 수 있고, 도파관 내의 공간으로 출력된 n개의 증폭된 분배신호는 출력 단자와 연결된 핀(pin)에 의해 수신 및 결합되어 단일의 증폭신호로 출력될 수 있다. The spatial power combiner 130 may receive the divided signals amplified from each of the n power amplifiers 120-1, 120-2,..., 120-n and combine them into a single amplified signal for output. The space power coupler 130 according to the embodiment of the present invention may be a coaxial waveguide space power coupler. Therefore, the spatial power combiner 130 has an amplified distributed signal input from each of the n power amplifiers 120-1, 120-2, ... 120-n, respectively, and n tapered pin lines (see FIG. 2) in the waveguide. The amplified distribution signals output to the space within the waveguide may be received and combined by a pin connected to the output terminal and output as a single amplified signal.

여기에서, 신호를 분배, 증폭 및/또는 결합한다는 것은 그 신호의 "전력(Power)"을 분배, 증폭 또는 결합한다는 의미로 해석할 수도 있다. 즉, 공간전력분배기(110)와 n개의 증폭기(120-1, 120-2, ... 120-n), 공간전력결합기(130)는 각각 입력되는 신호의 "전력"을 분배, 증폭, 결합하는 것으로 해석될 수 있다.Here, distributing, amplifying and / or combining a signal may be interpreted to mean distributing, amplifying or combining the "Power" of the signal.

Can be interpreted as

이상에서는 본 발명의 실시예에 따른 공간전력분배기(110)의 구성 및 결합관계에 대하여 설명하였다(본 발명의 실시예에 따른 공간전력분배기(110)의 보다 상세한 구성 및 결합관계는 미국등록특허 제9,287,605호 참조). 본 발명의 실시예에 따른 공간전력결합기(130)의 구성 및 결합관계는 공간전력분배기(110)와 동일하고, 공간전력분배기(110)의 출력포트(244)를 통해 증폭된 신호가 수신되고, 공간전력분배기(110)의 입력포트(236)를 통해 결합된 증폭신호가 출력되는 것이 상이할 뿐이다. 이하, 도 4를 참조하여 본 발명의 실시예에 따른 공간전력분배기 또는 공간전력결합기가 결합된 고출력 전력증폭기의 동작에 대하여 상세하게 설명한다. The configuration and coupling relationship of the space power divider 110 according to the embodiment of the present invention have been described above. 9,287,605). The configuration and coupling relationship of the space power combiner 130 according to the embodiment of the present invention is the same as the space power divider 110, the amplified signal is received through the output port 244 of the space power divider 110, It is only different that the amplified signal coupled through the input port 236 of the space power divider 110 is output. Hereinafter, an operation of the high output power amplifier coupled with the space power divider or the space power combiner according to the embodiment of the present invention will be described in detail with reference to FIG. 4.

도 4는 본 발명의 실시예에 따른 공간전력분배기 또는 공간전력결합기가 결합된 고출력 전력증폭기에 대한 블록 구성도이다. 4 is a block diagram illustrating a high output power amplifier in which a space power divider or a space power combiner is coupled according to an embodiment of the present invention.

도 4를 참조하면, 공간전력분배기(110)의 입력포트(236)를 통해 입력된 입력신호는 동축도파관(210)에서 n개의 신호로 분배되어 상응하는 출력케이블(140-1, 140-2, ... 140-n)을 통해 n개의 증폭기(120-1, 120-2, ... 120-n) 각각으로 출력될 수 있다. 여기서 입력신호는 10[GHz]　이상의 주파수 특성을 갖는 케이유 밴드(Ku band)에 상응하는 신호일 수 있다. 입력포트(236)를 통해 입력된 입력신호는 핀(232)를 통해 동축도파관(210)으로 전달될 수 있다. Referring to FIG. 4, an input signal input through the input port 236 of the spatial power divider 110 is divided into n signals in the coaxial waveguide 210 and corresponding output cables 140-1, 140-2, ... 140-n) may be output to each of the n amplifiers 120-1, 120-2, ... 120-n. The input signal may be a signal corresponding to a Ku band having a frequency characteristic of 10 [GHz] or more. The input signal input through the input port 236 may be transmitted to the coaxial waveguide 210 through the pin 232.

입력신호는 동축도파관(210)에서 내부도체(220)를 통해 동축도파관(210) 내부로 전자기파 형태로 방사될 수 있다. 전자기파 형태로 방사된 입력신호는 (n개의 트레이(250) 각각에 결합된) n개의 테이퍼 핀-라인(252) 각각에서 수신되어 n개의 분배신호로 출력될 수 있다. 이때, 각 테이퍼 핀-라인(252)은 각 출력포트(244)와 전기적으로 연결되어 있을 수 있다. 또한 제1 분배신호는 제1 출력케이블(140-1)을 통해 제1 증폭기(120-1)로 출력될 수 있고, 제2 분배신호는 제2 출력케이블(140-2)을 통해 제2 증폭기(120-2)로 출력될 수 있으며, 제n 분배신호는 제n 출력케이블(140-n)을 통해 제n 증폭기(120-n)로 출력될 수 있다. The input signal may be radiated in the form of electromagnetic waves from the coaxial waveguide 210 to the coaxial waveguide 210 through the inner conductor 220. The input signal radiated in the form of electromagnetic waves may be received at each of the n tapered pin-lines 252 (coupled to each of the n trays 250) and output as n distribution signals. In this case, each tapered pin-line 252 may be electrically connected to each output port 244. In addition, the first distribution signal may be output to the first amplifier 120-1 through the first output cable 140-1, and the second distribution signal may be output to the second amplifier through the second output cable 140-2. The n th distribution signal may be output to the n th amplifier 120-n through the n th output cable 140-n.

제n 분배신호 각각은 증폭된 후 공간전력결합기(130)에서 동일한 위상으로 결합되어야 하므로 n개의 전력증폭기(120-1, 120-2, ... 120-n) 각각으로부터 증폭된 n개의 분배신호 각각의 위상이 동일하여야 한다. 이를 위해서는 n개의 전력증폭기(120-1, 120-2, ... 120-n) 각각으로 입력되는 n개의 분배신호의 위상차가 동일하여야 한다. 그런데, 공간전력분배기(110)에서 출력되는 n개의 분배신호는 그 위상이 각각 상이할 수 있다. Since each of the n th distribution signals must be amplified and combined in the same phase in the spatial power combiner 130, the n distribution signals amplified from each of the n power amplifiers 120-1, 120-2, ... 120-n Each phase must be the same. To this end, the phase difference of the n distributed signals input to the n power amplifiers 120-1, 120-2, ... 120-n, respectively, must be the same. However, n distribution signals output from the space power divider 110 may have different phases.

따라서 n개의 출력케이블(140-1, 140-2, ... 140-n) 각각은 상응하는 분배신호의 위상에 따라 길이가 상이할 수 있다. 예를 들어 제1 분배신호가 제1 증폭기(120-1)에 입력되는 위상(이하, '기준위상'이라 칭함)을 기준으로(즉, 제1 출력케이블(140-1)의 길이를 기준으로) 나머지 출력케이블(140-2, ... 140-n)의 길이가 결정되는 경우를 가정한다. 이때, 제2 증폭기(120-2)와 연결된 제2 출력케이블(140-2)의 길이는 제1 분배신호와 제2 분배신호의 위상차에 의해 결정될 수 있다. 즉, 제1 분배신호와 제2 분배신호의 위상차가 없다면 제2 출력케이블(140-2)의 길이는 제1 출력케이블(140-1)의 길이와 동일할 수 있다. 또는 제1 분배신호와 제2 분배신호의 위상차가 있다면 제2 출력케이블(140-2)의 길이는 당해 위상차에 상응하는 만큼 제1 출력케이블(140-1)의 길이와 상이할 수 있다. 마찬가지로 제1 분배신호와 제n 분배신호의 위상차가 없다면 제n 출력케이블(140-n)의 길이는 제1 출력케이블(140-1)의 길이와 동일할 수 있다. 또는 제1 분배신호와 제n 분배신호의 위상차가 있다면 제n 출력케이블(140-n)의 길이는 당해 위상차에 상응하는 만큼 제1 출력케이블(140-1)의 길이와 상이할 수 있다. Therefore, each of the n output cables 140-1, 140-2,... 140-n may have a different length depending on the phase of the corresponding distribution signal. For example, the first divided signal is input to the first amplifier 120-1 based on a phase (hereinafter, referred to as a reference phase) (ie, based on the length of the first output cable 140-1). Assume that the lengths of the remaining output cables 140-2, ... 140-n are determined. In this case, the length of the second output cable 140-2 connected to the second amplifier 120-2 may be determined by the phase difference between the first distribution signal and the second distribution signal. That is, if there is no phase difference between the first distribution signal and the second distribution signal, the length of the second output cable 140-2 may be equal to the length of the first output cable 140-1. Alternatively, if there is a phase difference between the first distribution signal and the second distribution signal, the length of the second output cable 140-2 may be different from the length of the first output cable 140-1 by the corresponding phase difference. Similarly, if there is no phase difference between the first distribution signal and the nth distribution signal, the length of the nth output cable 140-n may be equal to the length of the first output cable 140-1. Alternatively, if there is a phase difference between the first distribution signal and the nth distribution signal, the length of the nth output cable 140-n may be different from the length of the first output cable 140-1 by the corresponding phase difference.

각 전력증폭기(120-1, 120-2, ... 120-n)는 공간전력분배기(110)로부터 n개의 분배신호를 각각 입력받아 증폭시켜 출력할 수 있다. 증폭되어 출력된 n개의 분배신호(이하, '증폭분배신호'라 칭함)는 공간전력결합기(130)의 n개의 입력포트(244) 각각을 통해 공간전력결합기(130)로 입력될 수 있다. 예를 들어, 제1 증폭분배신호는 제1 입력포트로 입력될 수 있고, 제2 증폭분배신호는 제2 입력포트로 입력될 수 있으며, 제n 증폭분배신호는 제n 입력포트로 입력될 수 있다. Each of the power amplifiers 120-1, 120-2,..., 120-n may receive and amplify n distribution signals from the space power divider 110. The amplified and output n distributed signals (hereinafter, referred to as an "amplified distribution signal") may be input to the spatial power combiner 130 through each of the n input ports 244 of the spatial power combiner 130. For example, the first amplification distribution signal may be input to the first input port, the second amplification distribution signal may be input to the second input port, and the nth amplification distribution signal may be input to the nth input port. have.

공간전력결합기(130)는 n개의 입력포트 각각을 통해 입력된 n개의 증폭분배신호를 구비된 n개의 테이퍼 핀-라인(252) 각각으로 출력할 수 있다. 각 테이퍼 핀-라인(252)은 입력된 증폭분배신호를 동축도파관(210) 내부로 전자기파 형태로 방사시킬 수 있다. 전자기파 형태로 방사된 증폭분배신호는 핀(232)를 통해 하나의 신호로 결합될 수 있다. n개의 증폭분배신호가 결합된 출력신호는 핀(232)과 연결된 출력포트(236)를 통해 외부 장치로 전송될 수 있다. The spatial power combiner 130 may output each of n tapered pin-lines 252 provided with n amplified distribution signals input through each of the n input ports. Each tapered pin-line 252 may radiate the input amplified distribution signal into the coaxial waveguide 210 in the form of electromagnetic waves. The amplified distribution signal radiated in the form of electromagnetic waves may be combined into one signal through the pin 232. The output signal combined with the n amplified distribution signals may be transmitted to an external device through an output port 236 connected to the pin 232.
