PC2749TB
3 V, SUPER MINIMOLD SILICON MMIC
WIDEBAND AMPLIFIER
FOR MOBILE COMMUNICATIONS
DESCRIPTION
The
µ
PC2749TB is a silicon monolithic integrated circuit designed as amplifier for mobile communications. This
IC is packaged in super minimold package which is smaller than conventional minimold.
The
µ
PC2749TB has compatible pin connections and performance to
µ
PC2749T of conventional minimold
version. So, in the case of reducing your system size,
µ
PC2749TB is suitable to replace from
µ
PC2749T.
This IC is manufactured using NEC’s 20 GHz f
T
NESAT
TM
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, this IC has excellent performance, uniformity and reliability.

Function and Applications
Internal Equivalent Circuit
INPUT
0.82
Signal input pin. A internal
matching circuit, configured
with resistors, enables 50
Ω
connection over a wide band.
This pin must be coupled to
signal source with capacitor
for DC cut.
Signal output pin. A internal
matching circuit, configured
with resistors, enables 50
Ω
connection over a wide band.
This pin must be coupled to
next stage with capacitor for
DC cut.
Power supply pin. This pin
should be externally equipped
with bypass capacity to
minimize ground impedance.
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
connected together with wide
ground pattern to decrease
impedance difference.

CAPACITORS FOR THE V
CC
, INPUT AND OUTPUT PINS
1 000 pF capacitors are recommendable as bypass capacitor for V
CC
pin and coupling capacitors for input/output
pins.
Bypass capacitor for V
CC
pin is intended to minimize V
CC
pin’s ground impedance. Therefore, stable bias can be
supplied against V
CC
fluctuation.
Coupling capacitors for input/output pins are intended to minimize RF serial impedance and cut DC.
To get a flat gain from 100 MHz up, 1 000 pF capacitors are assembled on the test circuit. [Actually, 1 000 pF
capacitors give flat gain at least 10 MHz. In the case of under 10 MHz operation, increase the value of coupling
capacitor such as 2 200 pF. Because the coupling capacitors are determined by the equation of C = 1/(2
πfZs).]
