Power amplifier circuit

A power amplifier circuit comprising:

• an input terminal;
• an output terminal;
• a first path between the input terminal and the output terminal;
• a second path between the input terminal and the output terminal, the second path being connected in parallel with the first path;
• a first amplifier in the first path, the first amplifier being operative when the power amplifier circuit is in a first mode;
• a second amplifier in the second path, the second amplifier being operative when the power amplifier circuit is in a second mode;
• a first matching circuit in the first path, the first matching circuit being located between the first amplifier and the output terminal;
• a first capacitor, the first capacitor having a first end and a second end, the first end of the first capacitor being connected to the first path between the first matching circuit and the output terminal;
• a first inductor having a first end connected to the second end of the first capacitor and a second end that is grounded;
• and
• a short-circuit switch connected in parallel with the first inductor,
• wherein the short-circuit switch is configured to be in a short-circuit state when the power amplifier circuit is in the first mode, such that the first and second ends of the first inductor are short-circuited in the short-circuited state, and is configured to be in an open-circuit state when the power amplifier circuit is in the second mode.
