DESCRIPTION

The UPC8125GR is a Silicon MMIC manufactured with the

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.
