Patent abstract

A transmitter for transmitting a signal is provided, in which the transmitter includes a power amplifier and a driver amplifier, an output of the driver amplifier being connected to an input of the power amplifier via a first load modulation device operable to match the impedance of the driver amplifier output with impedance of the power amplifier input. A second load modulation device can be connected to the output of the power amplifier and operable to match the impedance of the power amplifier output with input impedance of a further device. Envelope tracking can be applied to the power amplifier and the driving amplifier.
