The RF to IF section includes a frequency translated bandpass filter (FTBPF), an LNA, and a mixing section. The FTBPF includes a switching network and a complex baseband filter having an offset baseband filter response. The switching network is operable to frequency translate the offset baseband filter response to an RF frequency response such that the FTBPF filters the inbound RF signal by passing, substantially unattenuated, a desired RF signal component and by attenuating an image signal component and/or an undesired signal component. The LNA amplifies the filtered inbound RF signal and the mixing section mixes the amplified inbound RF signal with a local oscillation to produce an inbound IF signal. The IF to baseband section converts the inbound IF signal into an inbound symbol stream(s)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Saw-less receiver with offset RF frequency translated BPF","description":"A SAW-less receiver includes a front end module (FEM) interface module, an RF to IF section, and an IF to baseband section.
