Patent ID: 7729724

Claim:
A radio frequency (RF) front-end comprises: an antenna switch coupled to at least one antenna; a first receiver frequency band filter module having a first receiver frequency band pass region, wherein the antenna switch couples the first receiver frequency band filter module to the at least one antenna when a first inbound RF signal is received, wherein the first inbound RF signal is formatted in accordance with a first one of a plurality of protocols having a carrier frequency within the first receiver frequency band pass region, and wherein the first receiver frequency band filter module filters the first inbound RF signal to produce a first filtered inbound RF signal; a second receiver frequency band filter module having a second receiver frequency band pass region, wherein the antenna switch couples the second receiver frequency band filter module to the at least one antenna when a second inbound RF signal is received, wherein the second inbound RF signal is formatted in accordance with a second one of the plurality of protocols having a carrier frequency within the second receiver frequency band pass region, and wherein the second receiver frequency band filter module filters the second inbound RF signal to produce a second filtered inbound RF signal; a first transmitter frequency band filter module having a first transmit frequency band pass region, wherein, when enabled, the first transmitter frequency band filter module filters a first outbound RF signal to produce a first filtered outbound RF signal, wherein the first outbound RF signal is formatted in accordance with the first one of the plurality of protocols having a carrier frequency within the first transmit frequency band pass region; and a second transmitter frequency band filter module having a second transmit frequency band pass region, wherein, when enabled, the second transmitter frequency band filter module filters a second outbound RF signal to produce a second filtered outbound RF signal, wherein the second outbound RF signal is formatted in accordance with the second one of the plurality of protocols having a carrier frequency within the second transmit frequency band pass region and wherein the antenna switch couples the first or the second transmitter frequency band filter module to the at least one antenna in accordance with the enabling of the first or the second transmitter frequency band filter module.
