Power amplifier integrated circuit with tunable impedance matching

An integrated circuit comprising:

• a power amplifier having an output;
• an output node coupled to the output of the power amplifier;
• and
• a tunable impedance matching network comprising:
• a tunable inductor coupled to the output node, the tunable inductor comprising a plurality of switches configured to selectively modify the tunable inductor to have a first inductance in a testing mode and a second inductance in a functional mode.

A system comprising:

• a signal source configured to generate a signal;
• an antenna;
• an integrated circuit coupled between the signal source and the antenna, the integrated circuit comprising:
• a power amplifier having an output, wherein the power amplifier is configured to amplify the signal and provide the amplified signal to the antenna;
• an output node coupled between the output of the power amplifier and the antenna;
• and
• a tunable impedance matching network comprising:
• a tunable inductor coupled to the output node, the tunable inductor comprising a plurality of switches configured to modify the tunable inductor to have a selected one of:
• a first inductance associated with a testing mode;
• or
• a second inductance associated with a functional mode.
