Abstract
Disclosed is a power amplifier having an output stage (12) having a radio frequency (RF) output (14) and an RF input (16) and a driver stage (18) having a driver input (20) coupled to the RF input (16), a control input (22), and a driver output (24), wherein the driver stage (18) is configured to have a controllable soft compression characteristic that substantially neutralizes a gain expansion characteristic of the output stage (12). Also included is a controller (26) having a control output (28) coupled to the control input (22) of the driver stage (18), wherein the controller (26) is configured to generate a control signal at the control output (28) that controls the soft compression characteristic of the driver stage (18).
