DESCRIPTION
The UPC8194K is a Silicon Microwave Monolithic integrated
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.

Functions and Applications
15 VCC 2.7 to 3.3
(AGC,
REG.)
-
Supply voltage pin of AGC amplifier and
internal regulator.
16 IF_IN - 2.75 IF signal input pin.
This pin is input of AGC amplifier.
Balance input between 16, 17 pin.
Input frequency is 190 MHz.
17 IF_INb
-
2.75 IF signal input pin.
In the case of signal local input, this pin
must be decoupled with capacitor.
20 VPS
