Abstract :
A 1.22-GHz downconverter used in a dual-conversion tuner IC for OpenCable applications is presented. The downconverter is configured as an image-reject receiver and utilizes a trifilar transformer in conjunction with capacitively cross-coupled common-gate mixer input stages to achieve a large dynamic range with relatively low power consumption. Fabricated in a five-metal 0.35-μm, 27-GHz fT, silicon-on-insulator 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 noise figure, 33-dBmV P1dB, 56-dBmV IIP3, -72-dBc composite triple beat (CTB), -60-dBc cross-modulation, and 30-dB image rejection.
