Description
M/A-COM’s MAALSS0043 is a high dynamic
range, GaAs MMIC, low noise amplifier in a
lead-free SOIC-8, surface mount plastic package.
It employs external input matching to obtain
optimum noise figure performance and operating
frequency flexibility.

The MAALSS0043 also features flexible biasing to
control the current consumption vs. dynamic range
trade-off. The MAALSS0043 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 MAALSS0043 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 AMPS,
GSM, and ETACS base stations. It is also useful
as a gain block, buffer, driver, and IF amplifier in
both fixed and portable cellular and 900 MHz ISM
systems.
The MAALSS0043 is fabricated using a low-cost
0.5-micron gate length GaAs process.
The
process features full passivation for increased
performance reliability.

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

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.
