Description
M/A-COM’s MAAM12031 is a high performance
GaAs MMIC low noise amplifier in a low cost SOIC
8-lead surface mount package. The MAAM12031
employs a fully monolithic design which eliminates
the need for external tuning networks. It can be
biased using 3 or 5 volt supplies and has an option
for biasing at higher currents for increased dynamic
range.

The MAAM12031 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
Japanese Personal Handy Phone Service (PHS),
Private Branch Exchange (PBX) and Personal
Communications and Networks (PCS, PCN)
markets, as well as standard gain blocks, buffer
amps, driver amps and IF amps in both fixed and
portable systems.

M/A-COM’s MAAM12031 is fabricated using a
mature 0.5-micron gate length GaAs process. The
process features full passivation for increased
performance reliability.
Ground
1. Pins 1, 4, 5 and 8 must be RF and DC grounded as shown.
2. Pin 3 is the RF input, pin 6 is the RF output. VDD is
applied on pin 7. This pin must be bypassed with a 500 pF
surface mount MLC capacitor, mounted as close as
possible to pin 7, and RF decoupled with a chip inductor
having a minimum value of 15 nH (as shown in the
Recommended PCB Configuration).
Ordering Information
3. Pin 2 allows use of an external resistor to ground for
optional, higher current bias. For nominal current
operation no resistor is used. For optional 20 mA current
operation, connect a 35 to 40 ohm chip resistor (as show in
the Recommended PCB Configuration).
