Power amplifier systems with load control

A wireless device comprising:

• a memory;
• a user interface;
• a baseband sub-system;
• a transceiver;
• a power management component;
• and
• a power amplification system, the power amplification system including a power amplifier circuit, an output power control circuit that provides a plurality of values of capacitance, the output power control circuit having at least one load control capacitor coupled to a load control switch to control a value of the capacitance provided by the output power control circuit, and a balun coupled to the power amplifier circuit and to the output power control circuit.

A wireless module comprising:

• a packaging substrate;
• one or more surface-mount devices;
• a duplexer assembly;
• a front-end power management integrated circuit;
• a match component;
• an antenna switch module;
• and
• a power amplifier assembly including a power amplification system, the power amplification system having a power amplifier circuit, and an output power control circuit providing a plurality of values of capacitance, the output power control circuit having at least one load control capacitor coupled to a load control switch to control the value of the capacitance provided by the output power control circuit, and a balun coupled to the power amplifier circuit and to the output power control circuit.
