Abstract
There is provided a method of testing an RF transceiver circuit and an RF transceiver circuit arranged to be operable in a test mode comprising a transmitter circuit portion and a receiver circuit portion, the receiver circuit portion including a mixer. The method involves the transmitter circuit portion generating a modulated signal and the receiver circuit portion receiving a continuous radio frequency wave. The mixer mixes the modulated signal with a signal derived from the continuous radio frequency wave to produce an output. A remainder of the receiver circuit portion processes the output of the mixer.
