ABSTRACT:
An integrated circuit and method for receiving and transmitting signals of different frequency bands utilizes a switching device on a bypass current path to selectively route incoming and outgoing signals by circumventing a capacitive device on a receive signal path. The bypass current path is used to selectively conduct current through a variable resistance device on a transmit signal path to transmit or block signals through the variable resistance device.
