SILICON MMIC 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 base (bypass) 1 UPC2721GR UPC2722GR INTERNAL BLOCK DIAGRAM 8 OSC 7 OSC BUFFER RFIN1 RFIN2 (bypass) DESCRIPTION The UPC2721 and UPC2722 are L-Band frequency converters manufactured using the NESAT III MMIC process. These products consist of a double balanced mixer, local oscillator, IF preamplifier, and constant voltage generator. These devices are 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. The UPC2722 output amplifier is the collector of one side of a balanced amplifier pair and operates best into a high impedance load. The absence of capacitive coupling in the UPC2722 permits better performance at IF frequencies below 25 MHz. 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.
