Method and system for multi-band transceiver front-end architecture with reduced switch insertion loss

Abstract:

Methods and systems for a multi-band transceiver front-end architecture with reduced insertion loss may comprise, in a transceiver comprising a first plurality of switches (each with a common terminal coupled to a transmit signal path), a second plurality of switches (each with a common terminal coupled to a receive signal path), and a plurality of communications links: operatively coupling the transmit signal path to one of the communications links using one of the first switches when the transceiver is in a transmit mode, and operatively coupling the receive signal path to one of the communications links using one of the second switches when the transceiver is in a receive mode. An off capacitance of at least one of the switches may be reduced utilizing an operatively coupled inductive element. The inductive element may comprise an inductor operatively coupled in series with the transmit signal path.
