Abstract: A wideband-tunable radio frequency (RF) receiver having a tunable RF bandpass filter (RF BPF) and passive mixer-first receiver (PMF-Rx) is disclosed. The tunable RF BPF and PMF-Rx operate synergistically, exploiting the intrinsic impedance translation property of the PMF-Rx, to suppress out-of-band interferers as well as in-band interferers at the receiver front end and thereby enhance the receiver's signal-to-noise ratio and overall dynamic range. In one embodiment of the invention the tunable RF BPF and PMF-Rx are independently tunable and afford the receiver the ability to reject or suppress interferers that might not otherwise be able to be rejected or suppressed.
