Functional Block Diagram
Description
M/A-COM’s MAAL-008091 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 MAAL-008091 also features flexible biasing to
control the current consumption vs. dynamic range
trade-off. The MAAL-008091 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 MAAL-008091 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 MAAL-008091 is fabricated using a low-cost
0.5-micron gate length GaAs process.
The
process features full passivation for increased
performance reliability.

Handling Procedures
Please observe the following precautions to avoid
damage:
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.
3. Exceeding any one or combination of these limits may cause
permanent damage to this device.
4. M/A-COM does not recommend sustained operation near
these survivability limits.
5. When pin #2 is used to increase current (see note 8).
6. Thermal resistance (θjc) = +88°C/W.

Recommended PCB Configuration
Cross Section View
Rev. V2
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.
