Abstract

An S-band radar transmitter MMIC is reported containing a class-F power amplifier and a switched mode power supply. The integration of the power supply offers the possibility to optimize the power amplifier bias voltage for each individual device in a AESA antenna. This has several advantages such as amplitude tapering with preservation of efficiency, the reduction of spurious signals due to decoherence and the removal of single point of failure.
