DESCRIPTION
NEC's UPC8191K is a Silicon Microwave Monolithic Inte-
grated Circuit designed as a transmitter/TX section for W-
CDMA. The UPC8191K 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 en-
sure the highest reliability and perormance.
