Abstract:
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 frequency translated bandpass filter (FTBPF), an LNA, and a mixing section. The FTBPF includes a switching network and baseband impedances. The switching network is operable to frequency translate a baseband filter response to a first RF band frequency response and/or to a second RF frequency band response. The FTBPF filters the inbound RF signal to pass, substantially unattenuated, the first and/or second RF band signal components. The LNA amplifies the first and/or second filtered inbound RF signals and the mixing section mixes the first and/or second amplified inbound RF signals with a corresponding first and/or second local oscillation. The IF to baseband section converts the first and/or second inbound IF signals into first inbound symbol stream(s) and/or second inbound symbol stream(s).
