Abstract
A transmit-receive module for a phased array radar comprises a phase shifter, high-power amplifier, low-noise amplifier, and duplexer which are constituted with field-effect transistors and a control circuit for processing negative-voltage signal data to control and drive the above RF devices. Therefore, a compact small-power-consumption transmit-receive module is obtained because a level conversion circuit for driving the RF devices is disused and the RF devices are directly driven by a control circuit. Moreover, the entire transmit-receive module can be downsized because a plurality of unit arrays are constituted with one control circuit.
