DESCRIPTION
The UPC2726T is a Silicon RF Integrated Citrcuit which is
manufactured using the NESAT III process. The NESAT III
process produces transistors with f
T
approaching 20 GHz.
This amplifier was designed as a buffer amplifier for circuits
requiring differential inputs and outputs for increased common-
mode rejection.
NEC's stringent quality assurance and test procedures ensure
the highest reliability and performance.
