UPC2721GV

SILICON MMIC UPC2721GV L BAND DOWNCONVERTER FEATURES • WIDE BAND OPERATION UP TO 2.5 GHz • INTERNAL BALANCED AMPLIFIER FOR VCO • SINGLE ENDED PUSH-PULL IF AMPLIFIER • 5 V SINGLE SUPPLY VOLTAGE: ICC = 30 to 35 mA • LOW CURRENT DISSIPATION • TAPE AND REEL PACKAGING OPTION AVAILABLE OSC base (feedback) 2 OSC BUFFER INTERNAL BLOCK DIAGRAM OSC base (bypass) 1 OSC 8 RFIN1 7 RFIN2 (bypass) 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 Ω load. NEC's stringent quality assurance and test procedures ensure the highest reliability and performance. OSC collector (coupling) 3 6 GND IF AMP VCC 4 REG.
