Abstract

The invention discloses a Ku-frequency-range four-path radial waveguide power combiner which comprises a body, a base, a cover board and a probe. Four first waveguide ports are equidistantly arranged on the base in a circumferential direction. The top surface cover of the base is arranged on the base so that a first waveguide chamber is formed between the body and the base and the first waveguide ports can be communicated with the first waveguide chamber. The cover board covers the bottom surface of the body so that a second waveguide chamber is formed between the body and the cover board. The cover board is provided with a second waveguide port which is communicated with the second waveguide chamber. The bottom end of the probe is fixedly connected with the top surface of the base, and the bottom end successively penetrates through the first waveguide chamber and a central through hole on the body and extends into the second waveguide chamber. The probe is provided with a multi-step impedance conversion structure. The first waveguide ports and the second waveguide port are BJ140 standard waveguide ports. The Ku-frequency-range four-path radial waveguide power combiner has advantages of wide working frequency band, small insertion loss, high amplitude phase consistency, etc.

Description

technical field [0001] The invention relates to the field of microwave devices, in particular to a four-path waveguide power combiner working in the Ku frequency band. Background technique [0002] In a microwave application system, the power of the transmitter system determines the range and anti-interference ability of the entire system, and the high-power amplifier is an essential part of the transmitter system. Since the output power of microwave solid-state power amplifiers is not high, in order to obtain high-power output, the method of power synthesis is generally used to combine multiple power amplifiers in parallel to form an output. In this way, the output performance of the combined power amplifier depends largely on the performance of the power combiner, and the broadband low-loss power combiner is the key to realize the microwave broadband power amplifier. [0003] The existing power combiner has complex structure, large insertion loss and poor amplitude-phase ...
