A portable computing device includes an FEM, a SAW-less receiver, a SAW-less transmitter, and a baseband processing unit. The FEM isolates one or more outbound RF signals from one or more inbound RF signals. The SAW-less receiver converts the one or more inbound RF signals into one or more inbound intermediate frequency (IF) signals by frequency translating a baseband filter response to an IF filter response and/or an RF filter response. The SAW-less receiver filters the inbound RF signal(s) in accordance with the RF filter response and/or filters the inbound IF signal(s) in accordance with the IF filter response. The SAW-less transceiver then converts the inbound IF signals(s) into inbound symbol stream(s). The SAW-less transmitter converts outbound symbol streams(s) into the outbound RF signal(s). The baseband processing unit converts outbound data into the outbound symbol stream(s) and convert the inbound symbol stream(s) into inbound data. |
