The
μ
PC2771T is a silicon monolithic integrated circuit designed as the transmission PA’s driver for digital cellular
telephones. This +11.5 dBm P
1db
driver can get back-off to PA input level.
3 V supply operation is suitable for low voltage systems.
Due to the 50
cascadable and mini-mold package, this IC is suitable for high-density surface mounting.
The
μ
PC2771T is manufactured using NEC’s NESAT
TM
III silicon bipolar process (f
T
= 20 GHz). This process uses
a silicon nitride passivation film and gold electrodes. These materials protect the chip’s surface, prevent corrosion
and feature the low current and high-frequency characteristics transistors. Thus, this IC has excellent reliability and
electrical performance.
