DESCRIPTION
1
The UPC8195K is a Silicon Microwave Monolithic Integrated
Circuit designed as a transmitter/TX section for W-CDMA.
The UPC8195K is a TX-IF IC including IF-AGC amplifier and
modulator. This IC is suitable for kit-use for W-CDMA IF
section.
This IC was developed using NEC's new ultra high seed
silicon bipolar process.
NEC's stringent quality assurance and test procedures ensure the highest reliability and perormance.
