DATA SHEET
BIPOLAR ANALOG INTEGRATED CIRCUITS
µPC2747TB, µPC2748TB
3 V, SUPER MINIMOLD SILICON MMIC
AMPLIFIER FOR MOBILE COMMUMICATIONS
DESCRIPTION
The µPC2747TB, µPC2748TB are silicon monolithic integrated circuits designed as amplifier for mobile
communications. These ICs are packaged in super minimold package which is smaller than conventional minimold.
The µPC2747TB, µPC2748TB have compatible pin connections and performance to µPC2747T, µPC2748T of
conventional minimold version. So, in the case of reducing your system size, µPC2747TB, µPC2748TB are suitable
to replace from µPC2747T, µPC2748T.
These ICs are manufactured using NEC’s 20 GHz fT NESATTM lll silicon bipolar process. This process uses silicon
nitride passivation film and gold electrodes. These materials can protect chip surface from external pollution and
prevent corrosion/migration. Thus, these ICs have excellent performance, uniformity and reliability.
FEATURES
• High-density surface mounting
• Supply voltage
• Noise figure
• Upper limit operating frequency
