BIPOLAR ANALOG INTEGRATED CIRCUIT
PC8179TB
SILICON MMIC LOW CURRENT AMPLIFIER
FOR MOBILE COMMUNICATIONS
Document No. P14730EJ2V0DS00 (2nd edition)
Date Published August 2000 N CP(K)

DESCRIPTION
The
PC8179TB is a silicon monolithic integrated circuit designed as amplifier for mobile communications. This
IC can realize low current consumption with external chip inductor which can not be realized on internal 50
wideband matched IC. This low current amplifier operates on 3.0 V.
This IC is manufactured using NEC's 30 GHz f
max
UHS0 (Ultra High Speed Process) silicon bipolar process. This
process uses direct silicon nitride passivation film and gold electrodes. These materials can protect the chip surface
from pollution and prevent corrosion/migration. Thus, this IC has excellent performance, uniformity and reliability.

parts, when you need more isolation or gain. The application
herein, however, shows only examples, therefore the application can depend on your kit evaluation.

Function and Applications
Internal Equivalent Circuit
1
INPUT
-
1.09
Signal input pin. A internal
matching circuit, configured with
resisters, enables 50
connec-
tion over a wide band. This pin
must be coupled to signal source
with capacitor for DC cut.

GND
0
-
Ground pin. This pin should be
connected to system ground with
minimum inductance. Ground
pattern on the board should be
formed as wide as possible.
All the ground pins must be con-
nected together with wide ground
pattern to decrease impedance
defference.

OUTPUT

-
Signal output pin. This pin is de-
signed as collector output. Due
to the high impedance output,
this pin should be externally
equipped with LC matching
circuit to next stage. For L, a
size 1005 chip inductor can be
chosen.
6
V
CC
2.4 to 3.3
-
Power supply pin. This pin
should be externally equipped
with bypass capacitor to
minimize its impedance.
