Abstract
An analysis of the noise characteristics of the receiver based on a current-driven passive mixer is presented, taking into account the noise of the following blocks: the low-noise amplifier at input of the mixer, the mixer itself, and the transimpedance amplifier at output of the mixer. The noise at the output of the receiver, which is generated by the listed groups of noise sources, is analyzed. The noise figure of the receiver and its optimal (minimum) value are found taking into account the influence of parasitic capacitances of the switches of the mixer. The calculation results are confirmed by the simulation results.
