An apparatus and method are provided for reducing the output voltage in a power amplifier. The power amplifier contains a power supply, an amplifier stage, an impedance matching circuit, and a voltage reduction unit connected between the power supply and the amplifier stage. A power amplifier device within the amplifier stage has a gain bandwidth that covers multiple frequency bands. The output voltage of the power amplifier device is a composite voltage that contains fundamental and harmonic components that lie within the gain bandwidth. The voltage reduction unit reduces the supply voltage of the power amplifier device such that the composite output voltage is less than the breakdown voltage in the power amplifier device. The impedance matching circuit is coupled to the power amplifier device output and provides impedance matching for output signals of the fundamental and harmonic frequencies.

Apparatus and methods for providing hot-switching immunity for radio frequency switching circuits are disclosed. A radio frequency switching circuit may include both a mechanical switch and a solid-state switch. The mechanical switch may be configurable to couple an output path of a power amplifier to a subsequent component in its transmission path when in a first mechanical switch state and to decouple the output path of the power amplifier from the subsequent component when in a second mechanical switch state. The solid-state switch may be configurable to operatively decouple the mechanical switch from a radio frequency power source when in a first solid-state switch state but not when in a second solid-state switch state. The solid-state switch may be in the first solid-state switch state during transitions of the mechanical switch between the first and second mechanical switch states.

Apparatus and method for selective linearization of scalable fault tolerant frequency agile transmitters. In one embodiment, the method includes receiving timestamped carrier configurations and segmenting the timestamped carrier configurations into time segments having a pre-determined time length. The method also includes determining composite carrier configuration in a present time segment for a predetermined number of future time segments and determining a correction solution of a plurality of correction solutions associated with the composite carrier configuration in a mapping of a plurality of carrier configurations and the plurality of correction solutions. The method includes providing the correction solution to a linearizer of at least one of a plurality of multi-carrier power amplifiers. The plurality of power amplifiers are provided in one or more banks of multi-carrier power amplifiers.
