The integration of a Switch-Mode Power Supply (SMPS) with a High Power Amplifier (HPA) offers various benefits 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 efficiency optimization, the high switching frequency which separates the spurious contributions from the carrier and the improved control of the HPA supply voltage rise- and fall times. The latter… CONTINUE READING
