Power amplifier module

A power amplifier module comprising:

• a first amplifier circuit configured to amplify a radio frequency signal with a first gain and to generate a first amplified signal, wherein the first gain corresponds to a first control signal;
• a second amplifier circuit comprising an amplifier configured to amplify the first amplified signal with a second gain and to generate a second amplified signal, and an output matching network configured to perform impedance matching on the second amplified signal, wherein the second gain corresponds to a second control signal;
• and
• a control circuit configured to generate the first control signal and the second control signal,
• wherein the second control signal is configured to cause an adjustment of the second gain of the second amplifier by causing an adjustment of an impedance of the output matching network, and
• wherein the first control signal is configured to cause an adjustment of the first gain of the first amplifier circuit in a manner that compensates for a variation in the second gain resulting from a variation in the power-supply voltage of the second amplifier circuit.
