PC2709TB
5 V, SUPER MINIMOLD SILICON MMIC
MEDIUM OUTPUT POWER AMPLIFIER
DESCRIPTION
The PC2709TB is a silicon monolithic integrated circuits designed as 1st IF amplifier for DBS tuners. This IC is
packaged in super minimold package which is smaller than conventional minimold.
The
PC2709TB has compatible pin connections and performance to
PC2709T of conventional minimold
version. So, in the case of reducing your system size, PC2709TB is suitable to replace from PC2709T.
These IC is manufactured using NEC’s 20 GHz f
T
NESAT™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, this IC has excellent performance, uniformity and reliability.

Function and Applications
Internal Equivalent Circuit
Signal input pin. A internal
matching circuit, configured with
resistors, enables 50 connec-
tion over a wide band.
A multi-feedback circuit is de-
signed to cancel the deviations of
h
FE
and resistance.
This pin must be coupled to sig-
nal source with capacitor for DC
cut.
Signal output pin. The inductor
must be attached between V
CC
and output pins to supply current
to the internal output transistors.

CC
Power supply pin, which biases
the internal input transistor.
This pin should be externally
equipped with bypass capacitor
to minimize its 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 con-
nected together with wide ground
pattern to decrease impedance
defference.
