Abstract
In this paper, first from three angles, a reasonable choice for amplifiers, amplifier state to identify and match amp circuit design to discuss the different factors which should be taken into account in the design of the power amplifier circuit programs. And then take microwave power amplifier of the actual needs of the project for example, in accordance with the technical requirements of the product, combined with the experience accumulated in the microwave amplifier design and production. A P-band power amplifier with typical gain of 15 dB is designed in this paper. By reasonably choosing transistor and its operating point, the circuit topology design, matched impendence, the final power ampilier has the features of stable output power, low gain flatness,high linearity and high reliability etc.关键词
