3 V, SUPER MINIMOLD SILICON MMIC
WIDEBAND AMPLIFIER FOR MOBILE COMMUNICATIONS
DESCRIPTION
The
m
PC2745TB and
m
PC2746TB are silicon monolithic integrated circuits designed as buffer amplifier for mobile
communications. These ICs are packaged in super minimold package which is smaller than conventional minimold.
The
m
PC2745TB and
m
PC2746TB have each compatible pin connections and performance to
m
PC2745T/
m
PC2746T of conventional minimold version. So, in the case of reducing your system size,
m
PC2745TB/
m
PC2746TB
are suitable to replace from
m
PC2745T/
m
PC2746T.
These ICs are manufactured using NEC’s 20 GHz f

ä
III 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 IC have excellent performance, uniformity and reliability.
