A wireless communication apparatus comprising a linearising cicuit which is switched to effect power savings

摘要

An amplifier, having a linear operation region and a nonlinear operation region, amplifies a transmission signal. A linear compensation circuit 30 compensates the amplifier for linearity when operating in the nonlinear operation region. The operation of the linear compensation circuit is controlled so as to substantially bring the linear compensation operation to a stop when the amplifier operates in the linear operation region.
