Abstract
Systems and methods are disclosed for transmitting and receiving RF signals. An exemplary RF transceiver includes a signal generator, a frequency multiplier circuit, a receiver circuit, a transmitter circuit, and a switching device. The signal generator is configured to output a first signal and a second signal. The first signal comprises a local oscillator signal, and a frequency of the second signal is derived from a frequency of the first signal. The frequency multiplier circuit is configured to upconvert the output of the signal generator by frequency multiplication. The receiver circuit is configured to process a received signal using an upconverted first signal, and the transmitter circuit is configured to provide an upconverted second signal to a transmitter channel. The switching device is configured to provide the upconverted first signal to the receiver circuit and the upconverted second signal to the transmitter circuit.
