Abstract: The disclosed invention relates to a transceiver system having a bypass signal path that enables low power consumption. The transceiver system has transmission path and a reception path. The transmission path provides a signal from a transmission chain to an antenna for wireless transmission. The reception path provides a signal from the antenna to a reception chain. A duplex filter that provides isolation between the transmission and reception paths is connected between the antenna and the transmission and reception paths. A bypass signal path selectively exchanges signals between the transmission chain and the antenna along a conductive path that bypasses the duplex filter. By using the bypass signal path to selectively exchange signals between the transmission chain and the antenna the insertion loss of the duplex filter can be mitigated, allowing for the transceiver system to operate at a lower power.
