Abstract:
1. A radio frequency (RF) transceiver, comprising: a signal generator configured to output a first signal and a second signal, wherein the first signal comprises a local oscillator signal and a frequency of the second signal is derived from a frequency of the first signal; a frequency multiplier circuit configured to upconvert the first and second signals output by the generator by frequency multiplication, and to output an upconverted first signal and an upconverted second signal as separate signals; a receiver circuit configured to process a received signal using the upconverted first signal; a transmitter circuit configured to provide the upconverted second signal to a transmitter channel; and a switching device configured to provide the upconverted first signal to the receiver circuit and the upconverted second signal to the transmitter circuit, wherein the transmitter circuit comprises:
