Description

M/A-COM’s MAAL-008624 is a high dynamic

range, low noise GaAs MMIC amplifier in a low

cost, surface mount package. It employs external

input matching to obtain optimum noise figure

performance and operatin g frequency flexibility.

The MAAL-008624 also features flexible biasing to

control the current consumption vs. dynamic range

trade-off. The MAAL-008624 can operate from any

supply voltage in the 3 V to 8 V range. Its current

can be controlled over a range of 20 mA to 80 mA

with an external resistor.

The MAAL-008624 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

CDMA450 base stations. It is also useful as a gain

block, buffer, driver, and IF amplifier in both fixed

and portable cellular and 450 MHz ISM

systems.

The MAAL-008624 is fabricated using a low-cost

0.5-micron gate length GaAs process. The

process features full passivation for increased

performance reliability.

Handling Procedures

The following precautions should be observed to

avoid damage:

Static Sensitivity

Gallium Arsenide Integrated Circuits are sensitive

to electrostatic discharge (ESD) and can be

damaged by static electricity. Proper ESD control

techniques should be used when handling these

devices.

Cross Section View

The PCB dielectric between RF traces and RF ground

layers should be chosen to reduce RF discontinuities

between 50-ohm lines and package pins. M/A-COM

recommends an FR-4 dielectric thickness of 0.008” (0.20

mm) yielding a 50-ohm line width of 0.015” (0.38 mm).

The recommended RF metalization thickness is 1 ounce

copper.
