Abstract:
1. A communication device, comprising: at least one antenna; at least one transceiver switchably coupled to the at least one antenna, wherein the at least one transceiver, while operating in a dual transmission mode, generates a first carrier and at least one other carrier including a second carrier, and simultaneously propagates the first carrier and the at least one other carrier to at least one antenna; a series-shunt PIN diode switch comprising a series PIN diode and a shunt PIN diode, and which receives at least the first carrier at a first switch input port that is in series with the series PIN diode; and a controller that selectively activates the dual transmission mode by biasing both the series PIN diode and the shunt PIN diode in the on-state to cause the series-shunt PIN diode switch to propagate at least the first carrier which is transmitted via the series PIN diode to at least a first antenna.
