DESCRIPTION
The UPC8101GR is a Silicon Monolithic Integrated Circuit
(MMIC) which is manufactured using NEC's 20 GHz fT NESAT
III process. The Quadrature Modulator was designed for
digital mobile communications 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
up-converted outputs of the mixers are combined in a differential output amplifier. The resultant output signal is at frequency of fLO/2 + fI/Q. Buffers are provided at the LO, I and Q
inputs, and filtering is provided between the digital frequency
divider and the mixers. The device can be powered down by
grounding the Enable pin.
