–15 dBm INPUT, VARIABLE GAIN AMPLIFIER SILICON MMIC
FOR TRANSMITTER AGC OF DIGITAL CELLULAR TELEPHONE
BIPOLAR ANALOG INTEGRATED CIRCUITS
DESCRIPTION
The
µ
PC8130TA and
µ
PC8131TA are silicon monolithic integrated circuits designed as variable gain amplifier.
Due to 800 MHz to 1.5 GHz operation, these ICs are suitable for RF transmitter AGC stage of digital cellular
telephone. These ICs are lower distortion than conventional
µ
PC8119T and
µ
PC8120T so that –15 dBm input level
can be applied. These ICs also available in two types of gain control so you can choose either IC in accordance with
your system design. 3 V supply voltage and minimold package contribute to make your system lower voltage,
decreased space and fewer components.
The
µ
PC8130TA and
µ
PC8131TA are 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.
FEATURES

Function and Applications
Internal Equivalent Circuit
RF input pin. This pin should be
coupled with capacitor (eg 1000 pF)
for DC cut. Input return loss can be
improved with external impedance
matching circuit.
Ground pin. This pin should be
connected to system ground with
minimum inductance. Ground patt-
ern on the board should be formed
as wide as possible. Ground pins
must be connected together with
wide ground pattern to decrease
impedance difference.
RF output pin. This pin is designed
as open collector of high impedance.
This pin must be externally equipped
with matching circuits.
