Abstract
A single tone RF signal generator and a method of generating a single tone RF signal. The single tone RF signal generator includes an output and a power amplifier that has an input. The power amplifier is operable to receive an RF signal including a first harmonic corresponding to a single tone signal to be produced by the signal generator. The power amplifier is also operable to amplify the RF signal. The power amplifier is further operable to provide the amplified RF signal to the output of the signal generator. The single tone RF signal generator further includes a feedback circuit connected between the output of the signal generator and the input of the power amplifier. The feedback circuit is configured to add one or more predistortion harmonics to the RF signal received by the power amplifier for cancelling harmonics in the amplified RF signal provided by the power amplifier.
