Abstract :
This paper describes an integrated tuner for cable telephony in a 0.35 μm, 27 GHz SOI BiCMOS technology. The IC integrates a complete dual-conversion signal path including upconverter, downconverter, variable-gain amplifier, LO synthesizers with fully integrated voltage-controlled oscillators, gain control circuitry, as well as digital calibration and interface circuits. It accepts signals in the 200-880 MHz band and produces a 44 MHz IF. Drawing 168 mA from a 3 V supply, the tuner system has a worst case noise factor of 7.3 dB, system phase noise below -78 dBc/Hz at a 10 kHz offset, spurs below -42 dBc for 137 5 dBmV input channels, a gain of 60 dB, and gain control range of 68 dB. The 13 mm2 IC meets specifications across an outdoor temperature range of -40°C to 100°C in production lots.
