Problems solved by technology

This structure has the advantages of regular shape and high space utilization rate, but it has the disadvantage of inconvenient debugging of each channel separately, because there are no probes of other channels during separate debugging, so there is no mutual coupling. The probes of the channel are all extended in the same waveguide, and there is a strong mutual coupling between the probes, which requires unified debugging, which makes the adjustment more difficult

Abstract

The invention discloses a microwave and millimeter-wave modular power divider / combiner, which comprises a first waveguide, a second waveguide and an amplifier module. The first waveguide is coupled with a first transitional waveguide through a first coupling slot. One end of the first transitional waveguide is connected with one end of the amplifier module. The second waveguide is coupled with a second transitional waveguide through a second coupling slot. One end of the second transitional waveguide is connected with the other end of the amplifier module. One end of the first waveguide is a first input port, and the other end of the first waveguide is a first input short-circuit plane. One end of the second waveguide is a first output port, and the other end of the second waveguide is a first output short-circuit plane. The other end of the first transitional waveguide is a first short-circuit plane, and the other end of the second transitional waveguide is a second short-circuit plane. By the divider / combiner, high-power microwave and millimeter-wave signals can be output; the divider / combiner is high in space utilization rate and convenient to debug, and has a regular structural shape; the combination of any path number is realized in a modular way; and the shortcomings of difficulty in debugging, low expansibility and the like of the conventional microwave and millimeter-wave power division / combination network are overcome.

Description

technical field [0001] The invention relates to a microwave and millimeter wave spatial power distribution and synthesis network technology, which is used to distribute one input signal to multiple channels, excite multiple solid-state power amplifiers, and synthesize the signals output by the power amplifiers in phase to obtain high power output . Background technique [0002] In microwave and millimeter wave systems, the transmitter is one of the most critical components, and its output power directly determines the radius of action of the system, anti-interference ability, and communication quality and performance of the system. Solid-state transmitters have the advantages of simple power supply, small size, light weight, long life, and high duty cycle, but the low power generated by a single solid-state device is an inherent disadvantage. As the frequency increases, the device size decreases, and the output power of a single solid-state device also decreases. The higher...
