The invention relates to the field of high-frequency high-power radar transmitters, in particular to a solid power amplification device for a radar transmitter. The device comprises a gain control circuit, a linear amplification circuit and an energy consumption control circuit; the gain control circuit comprises two input ports, wherein one input port is used for receiving radio-frequency outputfrom a signal source or a system host, and the other input port is used for receiving output from an AGC control circuit; the output port of the gain control circuit is connected with the input port of the linear amplification circuit; the output port of the linear amplification circuit is connected with a load or an antenna; the input port of the energy consumption control circuit is used for receiving TP pulse output signals generated by the signal source or the system host; and the output signal of the energy consumption control circuit is used for controlling power-on or power-off of eachpower amplifier in the linear amplification circuit; therefore, the energy consumption of the radar transmitter is greatly reduced, and the device has the advantages of short preheating time, high efficiency, low failure rate and long service life.
Description
technical field [0001] The invention relates to the field of high-frequency and high-power radar transmitters, in particular to a solid-state power amplification device for radar transmitters. Background technique [0002] As a high-power radar transmitter, its basic indicators should be its efficiency and linearity. The pros and cons of these two technical indicators as well as the stability and reliability of performance are very important for radar transmitter systems. Traditional radar transmitters use electronic tubes as power amplifiers, which are bulky, consume a lot of energy, are heavy, have short lifespans, high failure rates, require warm-up time, and cannot meet the requirements of rapid response in modern warfare. Contents of the invention [0003] The object of the present invention is to provide a solid-state power amplification device for radar transmitters with low energy consumption and high linearity, thereby effectively improving the portability and per...
