Abstract
The present invention relates to a lineariser for use with an amplifier. The lineariser comprises an input means and an output means. Input matching means are provided to receive an input signal. A transistor is provided, said transistor being arranged to operate substantially close to a switched on condition. The transistor is arranged to apply a non-linear gain to said input signal. The output means output the non-linear gain signal to said amplifier. The lineariser may be used with a RF power amplifier. The lineariser may be used in elements of a communication system.
