Description
M/A-COM’s MAALSS0025 is a high dynamic
range, low noise GaAs MMIC amplifier in a low
cost, surface mount package. It employs external
input matching to obtain optimum noise figure
performance and operating frequency flexibility.
The MAALSS0025 also features flexible biasing to
control the current consumption vs. dynamic range
trade-off. The MAALSS0025 can operate from any
supply voltage in the 3 V to 8 V range. Its current
can be controlled over a range of 20 mA to 80 mA
with an external resistor.
The MAALSS0025 is ideally suited for use where
low noise figure, high gain, high dynamic range,
and low power consumption are required. Typical
applications include receiver front ends in
CDMA450 base stations. It is also useful as a gain
block, buffer, driver, and IF amplifier in both fixed
and portable cellular and 450 MHz ISM
systems.
The MAALSS0025 is fabricated using a low-cost
0.5-micron gate length GaAs process.
The
process features full passivation for increased
performance reliability.

Handling Procedures
The following precautions should be observed to
avoid damage:
7. Pin 2 allows use of an external resistor to ground for
optional, higher current. For 20 mA operation, no resistor is
used.
For IDD ~ 40 mA, R2 = 43 ohms;
IDD ~ 60 mA, R2 = 15 ohms;
IDD ~ 80 mA, R2 = 10 ohms.
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
devices.

Recommended PCB Configuration
Cross Section View
The PCB dielectric between RF traces and RF ground
layers should be chosen to reduce RF discontinuities
between 50-ohm lines and package pins. M/A-COM
recommends an FR-4 dielectric thickness of 0.008” (0.20
mm) yielding a 50-ohm line width of 0.015” (0.38 mm).
The recommended RF metalization thickness is 1 ounce
copper.
