Description

M/A-COM’s MAAM12021 is a high performance

GaAs MMIC low noise amplifier in a low cost SOIC

8-lead surface mount 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.

3. Pins 1, 4, 5 and 8 must be RF and DC grounded as shown.

4. 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).

5. 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).
