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.
