DESCRIPTION
NEC's UPC8194K is a Silicon Microwave Monolithic inte-
grated circuit designed as a receiver (RX) section for W-
CDMA. The UPC8194K is a RX-IF IC including IF-AGC
amplifier and demodulator. 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.
