A SAW-less receiver includes an FEM interface module, an RF to IF receiver section, and a receiver IF to baseband section. The RF to IF receiver section includes a mixing module, a mixed buffer section, and a frequency translated BPF (FTBPF) circuit module. The mixing module converts an inbound RF signal into an in-phase (I) mixed signal and a quadrature (Q) mixed signal. The mixed buffer section filters and buffers the I mixed signal and filter and buffer the Q mixed signal. The FTBPF circuit module frequency translates a baseband filter response to an IF filter response such that the FTBPF circuit module filters undesired signal components of the IF I signal and the IF Q signal to produce an inbound IF signal. The receiver IF to baseband section converts the inbound IF signal into one or more inbound symbol streams.
