Abstract
A power amplifier cell includes a first input arranged to receive an in-phase control signal, a second input arranged to receive a quadrature control signal, an input stage arranged to output a drive signal based at least partly on the received in-phase and quadrature control signals, and an output stage arranged to receive at an input thereof the drive signal output by the input stage, and to generate an output signal for the power amplifier cell in response to the received drive signal.
