Abstract

RF power is sampled and measured at the input and output of a solid state pow-er amplifier using directional couplers and matched square law detectors. Outputs from the detectors are applied to differential inputs of a DC operational amplifier. Outputs from the detectors are compared and filtered in the operational amplifier and the result-ing difference signal is applied to a control input on a switching type power supply.
The power supply converts a DC input voltage to the various positive and negative vol-tages required to operate the RF devices in the solid state power amplifier. When the control loop is closed, the supply voltage varies to maintain a constant operating point resulting in constant gain, efficiency, and linearity for the overall solid state power am-plifier despite variations in signal levels and signal composition. In another embodi-ment, the solid state power amplifier has a series of single-ended low power amplifiers terminating in an output high power module. In the output module, one medium power device acts as a driver stage for four high power devices connected in parallel. The out-put stages are hybrid coupled, and isolators before and after these hybrid coupled out-put stages isolate the driver from the final amplifiers and protect the output devices from reflected signals. A dynamically controlled PIN diode variable attenuator at the amplifi-er input allows the operating point of the amplifier to be selected and adjusted while the closed loop function is in operation. A hybrid matrix power amplifier system is also disclosed.
