Conventional technique may be used in binding structure, and details are not described herein again.Further, subtracting high waveguide input mode, details are not described herein again.
Metal separators can be arranged as required into a variety of shape and structures for being.In one embodiment of the invention,
Metal separators are to be arranged among wave-guide cavity wave to place one piece of metal partion (metp), and metallic channel is dug in centre so that metal separators exist
Left and right directions (Y-direction in Fig. 1 in XYZ coordinate system) is divided into the first metal separators 21 and the second metal separators 22.
Specifically, preceding part (and in Fig. 1 on the left of Y-direction) is arranged in wave-guide cavity wave 1 in the first metal separators 21, is used for
Microwave to partly entering wave-guide cavity wave 1 before wave-guide cavity wave 1 carries out isolation processing.The length of second metal separators 22 is micro-
The quarter-wave of wave working frequency is connect with the one end of isolation resistance 3 far from the first metal separators 21, for that will pass through
Unbalanced part, which is reflected back in isolation resistance 3, in treated the microwave of isolation resistance 3 is absorbed.
Isolation resistance 3 is arranged in wave-guide cavity wave 1, is connect with the first metal separators 21, for passing through the first metal
Unbalanced part is absorbed in the microwave of isolator 21.Specifically, isolation resistance 3 be fixedly connected on first metal every
From between device 21 and the second metal separators 22, and positioned at the first metal separators 21 with the second metal separators 22 by proximal end end
The point midway in face.It is that isolation resistance is welded on partition board before metal partion (metp) is packed into cavity when assembly.
In other embodiments, the first metal separators 21 of metal separators and the second metal separators 22 can be multiple
Metal cylinder；The axis of multiple metal cylinders of first metal separators 21 is mutually parallel, and along the central plane of wave-guide cavity wave 1
It is arranged side by side with identical spacing；The axis of multiple metal cylinders of second metal separators 22 is mutually parallel, and along the waveguide
The central plane of cavity 1 is arranged side by side with identical spacing.At this point, 3 both ends of isolation resistance respectively with the first metal separators 21 and
Two metal cylinders of second metal separators, 22 phase by proximal end connect, and positioned at the point midway of two metal cylinder axial directions.
Equally, it is that isolation resistance is welded on partition board before metal partion (metp) is packed into cavity when assembly.
The waveguide power synthesizer of the present invention, by the gold for increasing a grooving in microstrip probe reverse phase work(clutch structure
Belong to partition board and the isolation resistance that is connected across on the quarter-wave metallic channel in metal partion (metp) edge, improves between input port
Isolation performance, while improving the standing wave of micro-strip input port.When normal power distributes, increased metal partion (metp) is equivalent to
Electric wall, the isolation resistance being connected across on metallic channel do not work.When each input port has unbalanced signal, unbalanced signal meeting
The isolation resistance being connected across on the quarter-wave metallic channel in metal partion (metp) edge sponges, so as to improve port
Isolation and port match.
The present invention also provides a kind of waveguide power synthetic methods, include the following steps：
Step 1: by the way that the first metal separators 21 of the preceding part in wave-guide cavity wave 1 are arranged to from 1 front of wave-guide cavity wave
The microwave into wave-guide cavity wave 1 is divided to carry out isolation processing.
Step 2: by the way that unbalanced part in treated microwave is isolated in 3 absorption step one of isolation resistance.
Step 3: being that be the second metal separators of quarter-wave 22 will be handled working frequency in step 2 by length
Unbalanced part, which is reflected back in step 2, in microwave afterwards is absorbed.
Step 4: partly being exported after the step 3 treated microwave is from wave-guide cavity wave 1.
In the waveguide power synthesizer and waveguide power synthetic method of the present invention, Gao Bo is inputted and subtracted for microstrip probe
Input is led, respective power combing principle is as follows：
Microstrip probe input power synthesizes：
When the microwave signal of two-way reverse phase is coupled to waveguide cavity from 4 input port of microstrip circuit cavity by microstrip probe 5
After body 1, signal is transmitted and is superimposed in wave-guide cavity wave 1, is synthesized and is exported by 1 output port of wave-guide cavity wave, two-way imbalance portion
Point, due to the presence of metal separators, the position of metallic channel is transmitted and reflexed in wave-guide cavity wave 1, is inhaled by isolation resistance 3
It receives, realizes the isolation of two-way input signal.
Subtract high waveguide input power synthesis：
When the microwave signal of two-way reverse phase is input to wave-guide cavity wave 1 from high waveguide is subtracted, signal transmits simultaneously in wave-guide cavity wave 1
Superposition is synthesized by 1 output port of wave-guide cavity wave and is exported, two-way imbalance part, due to the presence of metal separators, in waveguide
The position that metallic channel is transmitted and reflexed in cavity 1, is absorbed by isolation resistance 3, realizes the isolation of two-way input signal.
In conclusion the waveguide power synthesizer and power combining methods of the present invention, had both completed waveguide and have arrived microstrip transition
Realize distribution/synthesis of two-way power simultaneously, and improve the isolation between each road and port standing wave, convenient for intermodule connection and
The system integration reduces uneven between multiloop loop system integrates the roads Shi Yin or even damages the unstability brought to system all the way；
In addition, the structure is directly realized power distribution/synthesis in Waveguide-microbelt transfer process, while realizing good isolation again,
It is carried out compared with cascade with a Waveguide-microbelt converter of the good wave guide power clutch redesign of a isolation performance is designed, structure
It is compacter, it is conducive to the Miniaturization Design of system.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, all answer by the change or replacement that can be readily occurred in
It is included within the scope of the present invention.Therefore, protection scope of the present invention should be with the scope of the claims
