Description
M/A-COM’s MAAM12032 is a high performance GaAs
MMIC low noise amplifier in a low cost SOIC 8-lead
surface mount plastic package. The MAAM12032
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 MAAM12032 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 Systems and
Networks (PCS, PCN) markets, as well as standard gain
blocks, buffer amps, driver amps and IF amps in both
fixed and portable systems.
Ordering Information
M/A-COM’s MAAM12032 is fabricated using a mature
0.5-micron gate length GaAs process. The process
features full passivation for increased performance
reliability.
* If specific reel size is required, consult factory for part
number assignment.

Notes:
4. Pins 1, 4, 5 and 8 must be RF and DC grounded as shown.
5. 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).
6. 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 30- to 35-ohm chip
resistor (as shown in the Recommended PCB Configuration).
