DESCRIPTION AND APPLICATIONS
The UPC2753GR is a frequency converter manufactured
with the NESAT III process. This product consists of an RF
input amplifier, Gilbert cell mixer, LO input buffer, IF amplifier
with AGC, external filter port, and IF output limiting amplifier.
This device was specifically designed for low cost GPS
recievers, mobile radios, and PCN applications.
NEC's stringent quality assurance and test procedures as-
sure the highest reliability and performance.

Notes:
1. Conversion Gain is -3 dB from Conversion Gain For fRF = 50 MHz.
2. Downconverter and AGC amplifier only.
3. PLO = -10 dBm.
4. Downconverter and IF amp may be operated separately.
Typical ICC for down converter is 5.5 mA (pin 15). Typical ICC for
IF amp is 1.4 mA (pin 14).
