Functional Block Diagram
Description
M/A-COM’s MAALSS0048 is a high dynamic range,
GaAs MMIC, low noise amplifier in a lead-free,
SOT-26 miniature surface mount, plastic package.
It employs external input matching to obtain
optimum noise figure performance and operating
frequency flexibility.
The MAALSS0048 also features flexible biasing to
control the current consumption vs. dynamic range
trade-off. The MAALSS0048 can operate from any
positive supply voltage in the 3 V to 8 V range. Its
current can be controlled over a range of 3 mA to 20
mA with an external resistor.
The MAALSS0048 is ideally suited for use where
low noise figure, high gain, high dynamic range, and
low power consumption are required.
Typical
applications included receiver front ends in PDC,
DCS-1800, DCS-1900 and other PCN/PCS
applications. It is also useful as a gain block, buffer,
driver, and IF amplifier in both fixed or portable PDC
and PCN/PCS systems.
The MAALSS0048 is fabricated using a low-cost
0.5-micron gate length GaAs process. The process
features full passivation for increased performance
and reliability. The MAALSS0048 is 100% RF
tested to ensure performance specification
compliance.

†
Reference Application Note M538 for lead-free solder reflow
recommendations.
Meets JEDEC moisture sensitivity level 1 requirements.
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.

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 di-
electric 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.
