Handling Procedures

Please observe the following precautions 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.

†

Reference Application Note M538 for lead-free solder reflow recommendations.

Meets JEDEC moisture sensitivity level 1 requirements.

Operating Instructions

The MAATSS0022 is designed to operate with 5 V

logic levels. The difference between +3 V and +5

V operation is minimal for small signal perform-

ance. IIP3, however, is a strong function of volt-

age. +3 V is the minimum voltage at which the

product will reliably operate.

The MAATSS0022 requires a parallel interface that

allows the user to enter a 5 bit digital word. Each

state increments the attenuation by 0.5 dB giving a

total range of 15.5 dB.

The MAATSS0022 is not internally DC blocked.

This means that the device requires DC blocking

capacitors on the RF1 and RF2 ports. M/A-COM

recommends 0.1 uF to allow for the entire fre-

quency range to be utilized.

Higher frequency

applications can use smaller value capacitors as

DC blocks.

parameter data can be found.
