The UPC2708T and UPC2711T are Silicon Monolithic inte-
grated circuits manufactured using the NESAT III process.
These devices are suitable as buffer amplifiers for wide-band
applications. They are designed for low cost gain stages in
cellular radios, GPS receivers, DBS tuners, PCN, and test/
measurement equipment.
NEC's stringent quality assurance and test procedures en-
sure the highest reliability and performance.
