VARIABLE GAIN AMPLIFIER SILICON MMIC
FOR TRANSMITTER AGC OF DIGITAL CELLULAR TELEPHONE
DESCRIPTION
The µPC8119T and µPC8120T are silicon monolithic integrated circuits designed as variable gain amplifier. Due to
100 MHz to 1.9 GHz operation, these ICs are suitable for RF transmitter AGC stage of digital cellular telephone. Two
types of gain control let users choose in accordance with system design. 3 V supply voltage and mini mold package
contribute to make system lower voltage, decreased space and fewer components.
The µPC8119T and µPC8120T are manufactured using NEC’s 20 GHz fT NESATTM 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
• Recommended operating frequency : f = 100 MHz to 1.92 GHz
• Supply voltage
: VCC = 2.7 to 3.3 V
• Low current consumption
: ICC = 11 mA TYP. @ VCC = 3.0 V
• Gain control voltage
: VAGC = 0.6 to 2.4 V (recommended)
• Two types of gain control
: µPC8119T = VAGC up vs. Gain down
µPC8120T = VAGC up vs. Gain up
• AGC control can be constructed by external control circuit.
• High-density surface mounting
(Forward control)
(Reverse control)
APPLICATIONS
• 1.9 GHz cordless telephone (PHS base-station and so on)
• 800 MHz to 900 MHz or 1.5 GHz Digital cellular telephone (PDC800M, PDC1.5G and so on)

Function and Applications
Internal Equivalent Circuit
RF input pin. This pin should be
coupled with capacitor (eg 1000
pF) for DC cut. This pin can be
input from 50 impedance signal
source without matching circuit.
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.
RF output pin. This pin is
designed as open collector of
high impedance.
This pin must be externally
equipped with matching circuits.

Supply voltage pin. This pin must
be externally equipped with low
pass filter (eg π type) in order to
suppress leakage from input pin.
This pin also must be equipped
with bypass capacitor (eg 1000
pF) to minimize ground
impedance.
Gain control pin. The relation
