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 21):
A multi-band radio frequency (RF) front-end circuit comprising:\n a first antenna port coupled to a first antenna; a second antenna port coupled to a second antenna; first RF circuitry comprising:\n a first transmit filter configured to pass an RF transmit signal in an RF transmit band; and \n a plurality of primary receive filters configured to pass the RF receive signal in one or more primary RF receive bands; \n second RF circuitry comprising:\n a plurality of receive filters configured to pass an RF receive signal in a plurality of RF receive bands; and \n at least one second transmit filter configured to pass the RF transmit signal in a second RF transmit band different from the RF transmit band; and \n control circuitry configured to:\n couple the first transmit filter to the first antenna port to transmit the RF transmit signal in the RF transmit band, wherein the RF transmit signal transmitted from the first antenna port is presented at the second antenna port as an interference signal in the RF transmit band; \n expand a bandpass bandwidth of a selected receive filter among the plurality of receive filters to include at least a portion of the RF transmit band; \n couple the selected receive filter between the second antenna port and an input impedance to form an interference signal path from the second antenna port to a ground; and \n adjust the input impedance to shunt the interference signal from the second antenna port to the ground.
