Background technique
Since the output power of single solid state power device is insufficient, power synthetic technique is current development Ka wave band high power
The unique technical approach of solid state power amplifier.
It cannot achieve Multi-channel high-efficient since dielectric loss causes the Insertion Loss of plane combiner circuit to steeply rise in Ka wave band
Synthesis, therefore synthesis effect is generally improved using low-loss rectangular waveguide or coaxial cavity structure in combiner circuit design
Rate.
In waveguide synthesis mode, the general Tee type structure either evil spirit T structure using the face E, the face H is synthesized.
The advantages of Tee type power divider/synthesizer is easy for realizing, combined coefficient is high；Disadvantage is then channel spacing from small,
Easily influence each other.Magic T structure realizes that the advantages of power divider/synthesizer is that isolation effect is good between road, and combined coefficient is high；The disadvantage is that
Structure is more complex, and bulk is big.
To sum up, lack a kind of power divider/synthesizer in the prior art, be able to satisfy that combined coefficient is high, isolation is good, and
Structure simply requires.

Tee type waveguide power distribution/synthesizer, a coupled room is set among cavity (3), and coupled room installs coupling terminal
(4), installation coupling load (5) at coupling terminal (4).
Coupling terminal reflects signal coupling back and couples load absorption, reaches the first power waveguide and the second power waveguide is believed
The purpose of number isolation, couples the load of load and is selected according to the size of reflection signal.
Coupling load had both balanced two output ports, played buffer action, and can output port all the way wherein
When appearance opens a way or is short-circuit, the power being transmitted back to is absorbed, the isolation between two output ports is improved.
The utility model has the beneficial effects that
Microstrip coupled port load in the utility model, had both balanced two power waveguide ports, plays isolation and makees
