Abstract
Because of associated disadvantages of narrow-band off-chip radio-frequency (RF) filtering, a mixer-first receiver front-end designed to tolerate blockers with minimal gain compression and noise factor degradation is disclosed. The mixer-first receiver front-end includes two separate down-conversion paths that help to minimize added noise and voltage gain prior to baseband filtering, which are critical factors in eliminating narrow-band off-chip RF filtering.
