DESCRIPTION
The UPC2721GV is a L-Band frequency converter manufac-
tured using the NESAT III MMIC process. This product con-
sists of a double balanced mixer, local oscillator, IF preampli-
fier, and constant voltage generator. It is available in a 8 pin
SSOP package. This device is designed for low cost cellular
radios, GPS receivers, PCS, and UHF TV tuner applications.
The UPC2721 output amplifier is a single-end push-pull ampli-
fier designed for operation into a 50 Ω load.
NEC's stringent quality assurance and test procedures ensure
the highest reliability and performance.
