Abstract

Изобретение относится к технике измерений в миллиметровом диапазоне длин волн и может быть использовано при разработке, испытаниях и исследованиях СВЧ-устройств, применяемых в радиолокации, измерительной технике, технике связи, медицине, системах безопасности, при проведении измерений параметров СВЧ-сигналов, где требуется на входе объекта измерения обеспечить стабильный уровень генерируемых сигналов, а для обработки измеренного сигнала обеспечить его перенос на промежуточную частоту с малыми потерями преобразования. Технические результаты изобретения являются формирование стабильного и более высокого по уровню мощности сигнала в гетеродинном канале опорного и измерительного сигналов измерителя комплексных коэффициентов отражения и передачи в миллиметровом диапазоне длин волн, что обеспечивает малые потери преобразования на смесителях, а также упрощение конструкции и снижение стоимости измерительной системы. Задачи достигаются тем, что разрабатывается конструкция измерителя, состоящего из измерительного блока и выносного преобразователя СВЧ-сигнала. В гетеродинном канале опорного и измерительного сигналов исключаются умножители частоты, сигнал от гетеродина подается непосредственно на входы смесителей на гармониках, а на выходах смесителей устанавливаются полосовые фильтры. Заявленный принцип измерения может применяться как в диапазоне частот от 118,1 до 178,4 ГГц, так и в диапазоне частот от 178,4 до 258,4 ГГц. При этом используются различные схемы реализации измерительного устройства.The invention relates to a measurement technique in the millimeter wavelength range and can be used in the development, testing and research of microwave devices used in radar, measuring technology, communication technology, medicine, security systems, when measuring parameters of microwave signals, where required at the input of the measurement object to ensure a stable level of the generated signals, and to process the measured signal, ensure its transfer to the intermediate frequency with low conversion losses. The technical results of the invention are the formation of a stable and higher signal power in the heterodyne channel of the reference and measuring signals of the meter of complex reflection and transmission coefficients in the millimeter wavelength range, which ensures low conversion losses on the mixers, as well as simplifying the design and reducing the cost of the measuring system. The tasks are achieved by the fact that the design of the meter is being developed, which consists of a measuring unit and an external microwave signal transducer. In the heterodyne channel of the reference and measuring signals, frequency multipliers are excluded, the signal from the local oscillator is fed directly to the inputs of the mixers at harmonics, and band-pass filters are installed at the outputs of the mixers. The declared measurement principle can be applied both in the frequency range from 118.1 to 178.4 GHz and in the frequency range from 178.4 to 258.4 GHz. In this case, various schemes for the implementation of the measuring device are used.
