Abstract

The invention discloses a P-band high power amplifier device, and relates to a power amplifier device of a P-band signal channel portion in the communication field. The P-band high-power amplifier comprises a propelling-stage power amplifier, a last-stage power amplifier, a switch controller, a power supply, a cooling unit, a monitoring interface and a circulator. In the P-band high power amplifier device, a modularization technology, an integration technology, a thermal design technology and a transmission line transformer technology are adopted to finish high-power synthesis, and the size is relatively small. The P-band high power amplifier has the functions of low-power protection, thermal protection and reflecting protection; the P-band high power amplifier device further has a rapid switching function and a very large switch-off depth, and is particularly suitable to be taken as a power amplifier device in a P-band half-duplex communication system.

Description

technical field [0001] The present invention relates to a P-band high-power amplifier device in the communication field, and is especially suitable as a power amplifier device in a high-power burst communication system. Background technique [0002] At present, there are many power amplifiers in the P frequency band, but there is a large gap in their switching speed, isolation between transceivers and the shutdown depth of power amplifiers, and it is difficult to apply them in burst communication and realize half-duplex communication. Way. In terms of volume, generally high-power amplifiers are relatively large, and it is difficult to apply them to small-volume chassis. Contents of the invention [0003] The object of the present invention is to avoid the disadvantages of the above-mentioned background technology, and provide a high-power amplifier device with fast switching speed, high transceiver isolation, large power amplifier shutdown depth, small volume and high pow...
