| 3 V, 900 MHz LOW NOISE SI MMIC AMPLIFIER FEATURES * 2.8 dB NOISE FIGURE * LOW VOLTAGE - LOW CURRENT: 6 mA at 3 V * LOW POWER CONSUMPTION: 18 mW TYP 18 20 GS UPC2748T NOISE FIGURE AND GAIN vs. FREQUENCY VCC = 3.0 V, ICC = 6mA 4.0 3.5 DESCRIPTION The UPC2748T is a Silicon Monolithic integrated circuit which is manufactured using the NESAT III process. The NESAT III process produces transistors with fT approaching 20 GHz. This amplifier was designed for 900 MHz receivers in cellular and cordless telephone applications. Operating on a 3 volt supply (1.8 volt minimum) this IC is ideally suited for handheld, portable designs. NEC's stringent quality assurance and test procedures ensure the highest reliability and performance.
