RF power amplifier system having a plurality of different power control modes
View Patent ↗A multiple mode RF power amplifier system is presented having N different power control modes for controlling the level of the output RF power relative to applied input power. The system includes a mode controller that receives one of N different mode select commands and in response thereto selects one of N different control modes to be operational. A gain controller controls the gain of the power amplifier system so as to control the level of the output RF power as a function of a control signal applied thereto. The control signal is applied to the gain controller wherein the control signal has a value dependent upon which of the N modes has been selected.
