Abstract :
A single-chip dual-mode direct-conversion RF receiver with an improved method for increasing the IIP2 of the downconversion mixer is described. An improved IIP2 over the 2-MHz baseband channel is achieved. The 0.35-μm SiGe BiCMOS RF receiver achieves 3.2-dB NF and -13-dBm IIP3 in 2-GHz mode, and 7.4-dB NF and -17-dBm IIP3 in 5-GHz mode. The current consumption in 2-GHz mode is 29.6 mA and in 5-GHz mode 28.4 mA. The chip area is 5.1 mm2.
