DESCRIPTION
The UPC2745T is a Silicon Monolithic integrated circuit which
is manufactured using the NESAT III process. The NESAT III
process produces transistors with f
T
approaching 20 GHz.
This device is suitable as a buffer amplifier for cellular and
cordless telephone applications. Operating on a 3 volt supply
(1.8 volt minimum) this IC is ideally suited for hand-held,
portable designs.
NEC's stringent quality assurance and test procedures en-
sure the highest reliability and performance.
