A 410-mW, 1.22-GHz downconverter in a dual-conversion tuner IC for OpenCable/spl trade/ applications

A 1.22-GHz Downconverter used in a dual-conversion tuner IC for OpenCable/spl trade/ applications is presented. Fabricated in a five-metal, 0.35-/spl mu/m, 27-GHz f/sub t/ SOI BiCMOS technology and consuming 124 mA from a 3.3-V supply, it downconverts the input to an IF of 44 MHz and achieves 26 dB gain, 23 dB gain control range, 5.1 dB NF, 33 dBmV P/sub 1dB/, 56 dBmV IIP/sub 3/, -72 dBc CTB, -60 dBc X-mod., and 30 dB image rejection.
