PRODUCT DESCRIPTION
S24 Package
SOT-89
The AGB3301 is one of a series of GaAs MESFET
amplifiers designed for use in applications
requiring high linearity, low noise and low distortion.
With a high output IP3, low noise figure and wide
band operation, the AGB3301 is ideal for 50W
wireless infrastructure applications such as Cellular
Base Stations, MMDS, and WLL. Offered in a low
cost SOT-89 surface mount package, the AGB3301
requires a single +5V to +9V supply, and typically
consumes less than 1 Watt of power.

AGB3301
Bias Circuit
A schematic of the basic, unmatched bias circuit for
the AGB Series Gain Blocks is shown in Figure 33.
The RF input and output terminations are 50W.
Inductor L1 provides DC power from VSUPPLY and
serves as an RF choke to maintain desired AC
performance. The input capacitor C1 and output
capacitor C2 are RF blocks that isolate DC current
from adjacent circuits. Capacitor C3 is used as an
RF bypass that minimizes noise from the supply.
In some applications, a feedback resistor R1 may
be added in series with L1, as shown in Figure 34,
for improved stability or to serve as a voltage drop for
operation from higher supply voltages.
Matching for RF Performance
The AGB3301 Gain Block amplifier can be used in
many fixed wireless frequency bands, such as the
824-894 MHz U.S. cellular bands, the 1850-1990 MHz
PCS band, the 880-960 MHz GSM band, the 24002500 MHz ISM band, and the 2500-2686 MHz MMDS
band. Reactive matching circuits may be designed

The evaluation board is 1.0” square, and is
fabricated on 0.031” thick FR-4 material. Figures 35
and 36 show the via hole locations and the layout
pattern on both sides of the evaluation board. The
vias have a 0.010” diameter and are plated through.
ESD Sensitivity
Electrostatic discharges can cause permanent
damage to this device. Electrostatic discharges
accumulate on test equipment and the human body,
and can discharge without detection. Although the
AGB3301 has some internal ESD protection, proper
precautions and handling are strongly
recommended. Refer to the ANADIGICS application
note on ESD precautions.

Evaluation Boards
A versatile evaluation board that enables users to
