DESCRIPTION
The UPC2749T is a Silicon Monolithic integrated circuit which
is manufactured using the NESAT III process. The NESAT III
process produces transistors with fT approaching 20 GHz.
This amplifier was designed for buffer amplifier applications in
GPS and PCS applications. Operating on a 3 volt supply this
IC is ideally suited for hand-held, portable designs.
NEC's stringent quality assurance and test procedures as-
sure the highest reliability and performance.
