Abstract :
A high-linearity SiGe monolithic downconversion mixer for 5-6 GHz wireless applications is implemented. The mixer offers a high-linearity thanks to taking the MIROMIXER topology with an inductive degeneration transconductance stage. IM3 products are largely cancelled so as to exhibit the state-of-the-art high input IP3. The performances of the mixer are 5.8 dBm input IP3, -7 dBm 1-dB compression point, 6.8 dB conversion power gain and 12.9 dB noise figure, respectively. Its power consumption is only 8.7 mW from a single 3 V power supply. The chip size is 991×989 μm2.
