Abstract

The invention belongs to the technical field of wireless communication, and particularly relates to a high-gain microwave power amplifier and a simulation method. The high-gain microwave power amplifier is arranged on a circuit board and comprises a radio frequency input end, a pre-stage amplification circuit, a driving-stage amplification circuit, an input matching circuit, a final-stage amplification circuit, an output matching circuit and a radio frequency output end. The signal input end of the pre-stage amplification circuit is connected with the signal output end of the radio frequency input end, the signal input end of the driving stage amplification circuit is connected with the signal output end of the pre-stage amplification circuit, and the signal input end of the input matching circuit is connected with the signal output end of the driving stage amplification circuit. According to the power amplifier, single-tube matching and multi-tube cascade matching are combined in the design process, the self-excitation phenomenon caused by improper circuit design is prevented, and high stability and high reliability of the power amplifier are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a high-gain microwave power amplifier and a simulation method. Background technique [0002] The main function of the microwave power amplifier is to amplify the input low-power microwave signal through the amplifying circuit composed of cascaded multi-stage power amplifier devices inside the power amplifier and output the amplified signal. With the development of microwave transistor technology and microwave amplifier design technology, the design of microwave power amplifiers has become more and more complex, and the requirements for its indicators have become higher and higher.
