Classification: CPC H | IPC H

Claim 16:
17. A mobile device comprising:
a bias circuit configured to receive a bias voltage and generate a bias signal;
at least one power amplifier stage configured to receive an input radio frequency signal and generate an output radio frequency signal;
at least first and second bias impedance components operatively coupled between at least one bias circuit and at least one power amplifier stage, the first and second bias impedance components configured to bias the at least one power amplifier stage with a variable impedance based on a control signal that is received separately from the bias circuit, each of the at least first and second bias impedance components configured to receive the same control signal; and
a modulator configured to generate a radio frequency transmit signal based on the output radio frequency signal.
