DESCRIPTION AND APPLICATIONS
The UPC8116GR is a Si MMIC Wideband IF Receiver IC
manufactured with the NESAT III silicon bipolar process. The
IC consists of a mixer, on-chip oscillator, IF amplifier, limiter
amplifier, OP amp, and built-in RSSI and power save func-
tions. The device operates over a wide 2.7 to 5.5 V supply
voltage range while drawing only 4 mA at 3 V. It is housed in
a small 20 pin SSOP package. The device was specifically
designed for use in low cost automotive keyless entry receiv-
ers, wireless security systems, UHF remote control, and other
low power Part 15 applications.
NEC's stringent quality assurance and test procedures assure
the highest reliability and performance.
