Abstract

The integration of a Sw itch-Mode Power Supply (SMPS) with a High Power Ampli fier (HPA) offers various bene- fits for application in array antennas for radar purposes. Among the most distinct advantages are removal of a single point of failure from the antenna system, individual bias control for local ef fi- ciency optimization, the high swit ching frequency which separates the spurious contributi ons from the carrier and the improved control of the HPA supply voltage rise- and fall times. The lat
