DESCRIPTION
The UPC2721 and UPC2722 are L-Band frequency convert-
ers 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 ampli-
fier designed for operation into a 50
鈩?/div>
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.
