DESCRIPTION
The UPC8125GR is a Silicon MMIC manufactured with the
NESAT III
TM
silicon bipolar process. The IC consists of a 1.8 -
2.0 GHz upconverter with AGC function and a 220 - 270 MHz IQ
modulator. The device operates over a wide 2.7 - 5.5 V supply
voltage range and features a power save function. The device
was specifically designed for digital mobile communication
applications such as 1900 MHz PCS and PHS handsets.
NEC's stringent quality assurance and test procedures ensure
the highest reliability and performance.
