DESCRIPTION
NEC's UPC2747TB and UPC2748TB are Silicon RFIC's which
are manufactured using the NESAT III process. These devices
are suitable as buffer amplifiers for cellular radio and other
communication receivers. The UPC2747TB/48TB are pin com-
patible and have comparable performance as the larger
UPC2747T/48T, so they are suitable for use as a replacement
to help reduce system size. The IC's are housed in a 6 pin
super minimold or SOT-363 package.
NEC's stringent quality assurance and test procedures ensure
the highest reliability and performance.
• HIGH DENSITY SURFACE MOUNTING:
6 pin super minimold or SOT-363 package
• GAIN:
UPC2747TB: Gs = 12 dB TYP
UPC2748TB: Gs = 19 dB TYP
• NOISE FIGURE:
UPC2747TB: NF = 3.3 dB TYP
UPC2748TB: NF = 2.8 dB TYP
• SUPPLY VOLTAGE:
VCC = 2.7 to 3.3 V
FEATURES
Note:
1.The gain at fL is 3 dB down from the gain at 900 MHz.
2.The gain at fU is 3 dB down from the gain at 900 MHz.
