Abstract
An apparatus includes: a first multiplexer configured to allow bi-directional communication over a first plurality of multiplexed communication bands that each include a corresponding transmit band and a corresponding receive band, wherein none of the transmit bands of the first multiplexer have transmit frequencies that overlap with any receive frequencies of any of the receive bands of the first multiplexer; a second multiplexer configured to allow bi-directional communication over a second plurality of multiplexed communication bands that each include a corresponding transmit band and a corresponding receive band, wherein none of the transmit bands of the second multiplexer have transmit frequencies that overlap with any receive frequencies of any of the receive bands of the second multiplexer; and an electromechanical band switch configured to selectively connect the first and second multiplexers to a common antenna.
