S-frequency band solid-state power amplifier

Abstract

The invention discloses an S-frequency band solid-state power amplifier, and aims at providing a 200W solid-state power amplifier which is high in S-frequency band output power, low in mass and easy for heat dissipation. The S-frequency band solid-state power amplifier is achieved according to the technical scheme that isolators are arranged at an input port and an output port of a solid-state power amplification module, an input signal is sent to a temperature compensation circuit after the input standing wave of the input signal is reduced to 1.3 or below by the input port isolator; the signal is subjected to temperature compensation and then sent to a driving chip to be amplified; the amplified signal is subjected to two times of power amplification and then sent to four power chips connected in parallel; the signal amplified by the power chips is subjected to two times of power synthesis and then sent to the output port isolator; the output signal is output by a microstrip-to-coaxial line circuit, and the microstrip-to-coaxial line circuit couples forward power and reverse power simultaneously to feed the power to a monitoring unit for monitoring; and the monitoring unit not only monitors the power information, but also monitors high-power AC / DC power supply current information and reports the monitored information to a system monitoring system.
