Abstract
A front-end receiver includes a first mixer of a first channel, a second mixer of a second channel, and a switching circuit that is configured to select the first mixer or the second mixer during a particular time period. Upon being selected, one of the first mixer or the second mixer is configured to deliver a down-converted signal that down-converts a respective RF signal of either the first or second reception channel. As the tasks of down-conversion and multiplexing are combined at the mixer level, the first and second reception channels may share a baseband circuit while being able to provide a well-balanced metrics of channel isolation, low noise figure, and linearity.
