PC8102T
RF AMPLIFIER IC FOR 150 MHz TO 330 MHz PAGER SYSTEM
DESCRIPTION
µ
PC8102T is a silicon monolisic integrated circuit designed as RF amplifier for 150 MHz to 330 MHz pager system.
Due to 1 V supply voltage, this IC is suitable for low voltage pager system. The package is a 6 pin mini mold suitable
for high-density surface mounting.
This IC is manufactured using NEC’s 20 GHz f
T
NESAT
TM
III silicon bipolar process. This process uses silicon
nitride passivation film and gold electrodes. These materials contribute excellent DC, AC performance. Thus, this
process is utilized for 1 V voltage IC.

INPUT
RF signal input pin. This pin
should be externally equipped
with matching circuit in accord-
ance with desired frequency.
This ground pin must be
connected to the system ground
with minimum inductance.
Ground pattern on the board
should be formed as wide as
possible. Track length should
be kept as short as possible.
Amplified signal output pin.
This pin should be externally
equipped with matching circuit
in accordance with desired
frequency.
