PARAMETRIC PERFORMANCE ANALYSIS OF RF MIXER

Suresh K.Rode, Gayatri M. Phade,Sandeep K. Shelke

This paper focuses on the design of radio-frequency (RF) mixers and their performance analysis, including a broad-band down converter mixer, an up converter mixer and a down converter mixer with high linearity. The basic mixer topology used in this report was the Gilbert cell mixer, which is the most popular active mixer topology used in modern communication systems. First, a broadband down converter mixer with variable conversion gain is designed using 0.350μm CMOS technology. The mixer worked from MHz to GHz, Frequency By changing the effective transistor size of the transconductor and the load, the mixer is able to work in three different modes with different conversion gain and power consumption. Second, an up and down converter mixer with sideband selection
