摘要

Modern wideband receivers need to operate linearly in the presence of strong out-of-band blockers. In this article, we introduce a blocker-tolerant harmonic rejection (HR) receiver, which can suppress blockers at the local oscillator harmonics. The suppression is achieved by applying the HR in two stages, such that the first HR already occurs at the first gain-stage output. The proposed receiver a...
