A transceiver, receiver, and transmitter are provided. The transmitter includes an in-phase path for an in-phase signal, a quadrature path for a quadrature signal, a first path associated with a first local frequency, a second path associated with a second local frequency, and a band selector for swapping the in-phase and quadrature paths with respect to the first and second paths so that one of the in-phase and quadrature paths communicates with the first path and the other communicates with the second path. The receiver includes an in-phase path, a quadrature path, a polyphase filter having first and second inputs and first and second outputs, and a selector for swapping the in-phase and quadrature receive paths to switch connection between the in-phase and quadrature receive paths and the first and second inputs. The transceiver may include the receiver and the transmitter.
