Advanced MMICs for Remote Sensing and Radar Applications

Modern remote sensing systems and radars are more and more based on electronically steered antennas. Instead of using one high power tube, each radiating element must contain a full T/R module allowing an individual modulation of amplitude and phase of both transmit and receive signal. The key elements in such systems are monolithic microwave integrated circuits. In this paper some general information about these components are given as well as the latest achievements in terms of power amplifiers are described. The CHA7010 is a 10W power amplifier (in pulsed mode) featuring high PAE and small size.
