Low Cost SOIC 8 Plastic Package
Description
M/A-COM’s MAAM12021 is a high performance GaAs
MMIC low noise amplifier in a low cost SOIC 8-lead surface mount plastic package. The MAAM12021 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 MAAM12021 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) and Japanese Personal Digital Cellular
(PDC-1500) markets, as well as standard gain blocks,
buffer amps, driver amps and IF amps in both fixed and
portable systems.
M/A-COM’s MAAM12021 is fabricated using a mature
0.5-micron gate length GaAs process. The process features full passivation for increased performance reliability.

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. VDDis 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 35- to 40-ohm
chip resistor (as shown in the Recommended PCB Configuration).
