DESCRIPTION
The UPC2748T 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 900 MHz receivers in cellular
and cordless telephone applications. Operating on a 3 volt
supply (1.8 volt minimum) this IC is ideally suited for handheld, portable designs.
