DESCRIPTION
NEC's UPC2798GR is a Silicon MMIC Downconverter manu-
factured with the NESAT?III silicon bipolar process. This
product consists of an input AGC amplifier, mixer, local oscil-
lator, and video amplifier. It is housed in a small 20 pin SSOP
package. The device is designed for use as an IF downconverter
for digital CATV settops and cable modems utilizing QAM
modulation.
NEC's stringent quality assurance and test procedures ensure
the highest reliability and performance.
ELECTRICAL CHARACTERISTICS (T A = 25 ° C, RF = 45 MHz, L O = 55 MHz, P LO = -10 dBm, unless otherwise specified)
