Active power compensation and broad-spectrum multi-channel military-grade electric field suppression device

Abstract

This invention, as an active power compensation and broad-spectrum multi-channel military-grade electric field immunity device, includes: a control computer, a signal generator, a power meter, an active power compensation device, a first power amplifier, a first directional coupler, and a first transmitting antenna. The active power compensation device is used to monitor and control the signal output power in real time. The control includes compensation control and power upper limit protection. The first directional coupler is used to capture forward and reverse power signals and transmit them back to the power meter, thereby continuously monitoring the power status in the test device circuit and preventing damage to the power amplifier or related test equipment due to factors such as abnormal output power, load mismatch, or wiring errors that are not detected in time.
