R.F. output power control

摘要

An R.F. power amplifier circuit comprising a power control loop is described. The power control loop includes an R.F. power amplifier having a power control input and a power supply input as well as at least one feedback path coupled between the power control input and the power supply input of the power amplifier. The feedback path includes at least one variable loop element that has a control terminal configured to reduce variations of control loop parameters.
