Description

technical field [0001] The invention relates to a solid-state power amplifier in the communication field, in particular to an S-band continuous wave solid-state high-power amplifier device. Background technique [0002] At present, the demand for S-band high power amplifiers in communication systems is increasing rapidly. The existing S-band high power amplifiers mostly use klystron power amplifiers developed by imported CPI companies. output powerP -1 All ≤1kW, which cannot meet the user's high-power, wide-band communication requirements. In addition, most of the existing S-band high-power amplifier power combiners use multi-level coaxial (microstrip line) synthesis, which is large in size, low in power, high in loss, and low in efficiency. The harmonic filter uses 1 / 4, 1 / 2 waveguide wavelength membrane chip filter has large structure size, large loss and complicated debugging. Contents of the invention [0003] The purpose of the present invention is to provide an S-...
