DESCRIPTION
The UPC8101GR is a Silicon Monolithic Integrated Circuit (MMIC) which is manufactured using NEC's 20 GHz f T NESAT III process. The Quadrature Modulator was designed for digital mobile munications in general, and the CT2 band requirements in particular. Operating on DC bias voltages as low as 2.7 volts, this IC is ideal for handheld/portable designs. The UPC8101GR takes an external LO signal, and digitally divides its frequency by two to generate the quadrature LO required for the dual internal mixer circuits. These mixers also receive external in-phase (I) and quadrature (Q) signals. The...
