The utility model can adopt unsymmetric structure, also can adopt symmetrical structure.The maximum characteristics of the phase power splitters such as constant amplitude that constitute when adopting symmetrical structure are that two notional phase difference and amplitude differences between the output are zero, be far smaller than the E-ground roll that generally adopts and lead the phase difference of crack electric bridge, namely the phase difference between output port A, the output port B is far smaller than the phase difference that the H-ground roll that generally adopts is led the crack electric bridge.Can to lead 90 degree phase differences of crack electric bridge than E-ground roll little for the notional phase difference during dissymmetrical structure, make phase compensation easily, bandwidth is wideer.The T type knot that the isolation of two output ports is far superior to generally adopt, Y type knot power splitter.Because the E-ground roll is led locational notable difference between two output ports of crack electric bridge and the input, the phase difference of two output in whole working band all about 90 degree.In waveguide power divider, we usually need between two outputs of power splitter phase difference in whole working band less than certain value, such as 3 degree or 5 degree.In order to satisfy this equiphase requirement, the most frequently used method is two outputs connection waveguide phase compensating circuits of leading the crack electric bridge at the H-ground roll.There is work zone width in this compensating circuit and increases the problem of power splitter volume.Particularly when adopting multistage H-ground roll to lead crack electric bridge formation multichannel power division network, the problems referred to above are more serious.Not almost not isolating of the T type knot that adopts, Y type knot power splitter two output ports, thus can influence each other between the amount of the causing output port.Power splitter of the present utility model, output port A, output port B are good with respect to the input port symmetry, have guaranteed that power and the phase place of output port A, output port B is identical.Again because the existence of isolated port A and isolated port B, thereby the isolation that has guaranteed two output ports is very high.Therefore, output port A, the output port B phase place of the miniaturization H type E face power divider that the utility model provides can be accomplished identical, have between output port A, the output port B 20dB with good isolation, can be used as single power splitter and use, particularly can be connected in series formation multichannel power division network and use.Device has clear superiority aspect performance, bandwidth of operation and the volume.
Operation principle of the present utility model can be summarized as follows under the situation of symmetric form rectangular coupled cavity and rectangle input and output waveguide.Cross section is that the input port of rectangle has mainly encouraged two waveguide mode of operations, i.e. TE10 pattern and TE30 pattern in the coupling cavity of the cuboid structure that is coupled by the E face.The ripple of these two patterns all will be propagated along the input waveguide axis direction.Because the guide wavelength difference of these two patterns, at the other end of coupling cavity, the power that output port A and output port B are coupled out from coupling cavity be the power that from the ripple of two mode of operation TE10 patterns and TE30 pattern, is coupled out respectively and.By width and the length of choosing coupling cavity, and size and the position of input port, isolated port B, isolated port C and output port A, output port B, can make the reflection of output port A and output port B place very little.At this moment, all energy are all exported from output port A and output port B coupling basically.Because two mode of operation TE10 patterns of input port excitation and TE30 satisfy naturally at isolated port A, isolated port B place and anti-phasely disappear mutually, the power that is coupled out from isolated port A, isolated port B is all very little, thereby isolated port A, isolated port B are used as isolation end.In order further to widen the bandwidth of operation of device, the shape of coupling cavity, particularly width can suitably change to axis along the front and back of input port, can also increase groove or metal bump (metal column) in coupling cavity.Each input/output terminal can increase one or more levels matching section.Coupling cavity and input port, isolated port A, isolated port B and output port A, output port B are shaped as other when distortion, and the operation principle of this miniaturization H type E face power divider also can be set forth and understands according to above content.
The power output of two output ports of the present utility model is identical in wideer working band with phase place, can be used as the good waveguide power divider of amplitude-phase consistency, is particularly suitable for serial connection and constitutes the multichannel power division network.That the utility model also has is simple in structure, volume is little, the characteristics that difficulty of processing is low.The utility model can be widely used in that antenna array, phased array radar and power are synthetic, missile guidance, military affairs and civil area such as communicate by letter.
