Abstract:
Embodiments of the disclosure include a multi-band radio frequency (RF) front-end circuit. When a first antenna transmits an RF transmit signal in an RF transmit band, a second antenna may receive the RF transmit signal as an interference signal. The multi-band RF front-end circuit includes multiple receive filters for receiving an RF receive signal in multiple RF receive bands. A selected receive filter among the multiple receive filters is opportunistically reconfigured to help suppress the interference signal. Specifically, a bandpass bandwidth of the selected receive filter is expanded to include at least a portion of the RF spectrum of the interference signal. By doing so, it is possible to shunt the interference signal to a ground through the selected receive filter. As a result, it is possible to reduce an adverse impact of the interference signal to improve RF performance of the multi-band RF front-end circuit.

Claim (Index 17):
The multi-band RF front-end circuit of  claim 1  wherein:\n the first RF circuitry comprises a long-term evolution (LTE) band  1  transmit filter configured to pass the RF transmit signal in LTE uplink band  1 ; \n the second RF circuitry comprises an LTE band  25  receive filter configured to pass the RF receive signal in LTE downlink band  25 ; and \n the control circuitry is further configured to:\n expand the bandpass bandwidth of the LTE band  25  receive filter to include at least a portion of the LTE uplink band  1 ; and \n couple the LTE band  25  receive filter between the second antenna port and the input impedance to form the interference signal path to shunt the interference signal from the second antenna port to the ground.
