DESCRIPTION
1
NEC's UPC8194K is a Silicon Microwave Monolithic integrated circuit designed as a receiver (RX) section for WCDMA. The UPC8194K is a RX-IF IC including IF-AGC
amplifier and demodulator. This IC is suitable for kit-use for WCDMA 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.
