DESCRIPTION
The UPC8125GR is a Silicon MMIC manufactured with the NESAT IIITM 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.
