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.

1 Input 0.81Signal input pin. An internal matching
0.82circuit, configured with resistors, enables
50 Ω connection over a wide bandwidth.
A multi-feedback circuit is designed to
cancel the deviations of hFE and resistance.
This pin must be coupled to the signal source
with a blocking capacitor.
4 Output 2.791Signal output pin. An internal matching
2.722circuit, configured with resistors, enables
50 Ω connection over a wide bandwidth.
This pin must be coupled to the output
load with a blocking capacitor.
6VCC 2.7 to 3.3 Power supply pin. This pin should be
externally equipped with a bypass capacitor
to minimize ground impedance.
2 GND 0 Ground pin. This pin should be connected
3 to system ground with minimum inductance.
5 Ground pattern on the board should be
formed as wide as possible. All the ground
pins must be connected together with wide
ground pattern to minimize impedance
difference.
