Transceiver

Abstract

A transceiver comprising a first frequency signal generator for generating a reception frequency signal, and a second frequency signal generator for generating a transmission frequency signal. The first frequency signal generator is coupled to the second frequency signal generator to supply the reception frequency signal to the second frequency signal generator as a reference frequency signal.
