The Integral Circuit of Windband High Frequency Quadrature Demodulator


M.S. Bychkov

The integrated microcircuit of the quadrature demodulator was designed on technology SiGe BiCMOS 0.25 um. The crystal's area is 2.3х1.2 mm2, the case is a MiniDIPP with 16 outputs. The input band is from 100 MHz to 6 GHz, the output band is from 0 to 1200 MHz. Two modes of a current’s consumption: for signals with a compression point close to -0,7 dBm and for rather powerful signals close to +5.5 dBm. The consumption is 0.9 W in the mode of the raised linearity and 0.43 W in the mode of the lowering consumption of a current. There are the special layout’s methods for reducing the amplitude and phase mismatches in channels I and Q.
