DESCRIPTION
The
µ
PC2723T is a silicon monolithic integrated circuit designed for miniature AGC amplifier. This amplifier realizes Auto
gain control with external control circuit. This IC operates up to 1.1 GHz and therefore is suitable for DBS tuner, mobile
telephone and other applications.
The
µ
PC2723T is manufactured using NEC’s 20 GHz f
T
NESAT™
III
silicon bipolar process. This process uses silicon
nitride passivation film and gold metallization wirings. These materials can protect the chips from external pollution and
prevent corrosion/migration. Thus, this IC has excellent performance, uniformity and reliability.

Functions and Explanation
Must be connected bypass capacitor (e.g. 1 500 pF) to minimize
ground impedance.
Must be connected to the system ground with minimum inductance.
Ground pattern on the board should be formed as wide as possible.
(Track length should be kept as short as possible)
Must be coupled with capacitor (e.g. 1 500 pF) for DC cut.
Supply voltage 5.0
±
0.5 V for operation. Must be connected bypass
capacitor (e.g. 1 500 pF) to minimize ground impedance.
Can be used for auto gain control. The control can be governed by
supply voltage to this pin. AGC performance can be adjustable by
R
AGC
value. (e.g. 15
Ω).
Input frequency from an external VCO output.
Must be coupled with capacitor (e.g. 1 500 pF).
