METHOD OF CONTROLLING POWER AMPLIFIER OF RADIO FREQUENCY SIGNAL AND RADIOELECTRONIC DEVICE CONTAINING POWER AMPLIFIER OF RADIO FREQUENCY SIGNAL

摘要

FIELD: radio engineering, communication.;SUBSTANCE: in the method of controlling the radio frequency power amplifier in the receiving-transmitting microwave module of the active phased array antenna of a radar station operating in a pulsed mode, a preliminary measurement of the radio frequency signal output power at a predetermined temperature and frequency range is performed to form an array of temperature and frequency corrections to the amplitude of the radio frequency signal and subsequent amplitude control by changing the voltage applied to the power amplifier, containing transistors operating in a deep saturation mode. The receiving-transmitting microwave module comprises a receiving-transmitting channel, a radio frequency signal power amplifier, a control device, and a modulator providing a pulsed power supply control.;EFFECT: increasing the accuracy and speed of the radio frequency signal amplitude adjustment by controlling the power amplifier using transistors operating in the deep saturation mode.;2 cl, 2 dwg
