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 an RF frequency translated bandpass filter (FTBPF), an LNA, and a mixing section. The RF FTBPF frequency translates a baseband filter response to an RF filter response and filters an inbound RF signal in accordance with the RF filter response, wherein the inbound RF signal includes a loss error due to switching loss and/or inductor loss. The RF FTBPF also compensates the loss error based on a negative resistance. The LNA amplifies the compensated inbound RF signal and the mixing section mixes the amplified inbound RF signal with a local oscillation to produce an inbound IF signal. The receiver IF to baseband section converts the inbound IF signal into one or more inbound symbol streams.
A surface acoustic wave (SAW)-less receiver comprises:
A radio frequency (RF) to intermediate frequency (IF) receiver section comprises:
