<p>An R.F. power amplifier circuit (10) comprising a power control loop (12) is described. The power control loop (12) includes an R.F. power amplifier (22) having a power control input (34) and a power supply input (36) as well as at least one feedback path coupled between the power control input (34) and the power supply input (36) of the power amplifier (22). The feedback path includes at least one variable loop element (18) that has a control terminal (46) configured to reduce variations of control loop parameters.</p> |
