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. OSC collector (coupling) 3 IF AMP VCC 4 REG. MIX 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.
