Description
M/A-COM’s MAALSS0042 is a high performance
GaAs MMIC low noise amplifier in a lead-free SOIC
8-lead surface mount plastic package.
The
MAALSS0042 employs a monolithic 3-stage selfbias design and a simple external matching network
to obtain minimum noise figure.

The MAALSS0042 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 the Global
Positioning System (GPS) market, as well as
standard gain blocks, buffer amps, driver amps, and
IF amps in both fixed and portable systems.
M/A-COM’S MAALSS0042 is fabricated using a
mature 0.5-micron gate length GaAs process. The
process features full passivation for increased
performance reliability.

3. Pins 1, 3, 4, 5, 7, and 8 must be RF and DC grounded (see
Recommended PCB Configuration).
4. Pin 2 is the RF input and must be connected to the simple
matching network shown in the Application Schematic.
5. Pin 6 is the RF output. VDD is also applied on Pin 6.
