Advances in the design of wideband receivers

To be practical wideband receivers must tolerate large out-of-band blockers which can desensitize the receiver through gain compression or reciprocal mixing with LO phase noise. This paper reviews how a new noise-cancelling receiver architecture - that utilises 3 important circuit innovations - mitigates gain compression without compromising noise figure. While the architecture is still susceptible to reciprocal mixing it is shown how a recently proposed reciprocal mixing cancelling technique (if incorporated into the receiver) can eliminate the need for a dramatic rise in LOGEN current.
