DESCRIPTION
The UPC2721GV is a L-Band frequency converter manufactured using the NESAT III MMIC process. This product consists of a double balanced mixer, local oscillator, IF preamplifier, 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 amplifier designed for operation into a 50 load. NEC's stringent quality assurance and test procedures ensure the highest reliability and performance.
