Description

M/A-COM’s AT-106-PIN is a GaAs FET 6-bit digital

attenuator with a 1 dB minimum step size and 50 dB

total attenuation. This attenuator and integral TTL

driver is in a hermetically sealed ceramic 24-lead

surface mount package. The AT-106-PIN is ideally

suited for use where accuracy, fast switching, very

low power consumption and low intermodulation

products are required. Typical applications include

dynamic range setting in precision receiver circuits

and other gain/leveling control circuits. Environ-

mental screening is available. Contact the factory

for information.

3. Exceeding any one or combination of these limits may cause

permanent damage to this device.

4. M/A-COM does not recommend sustained operation near

these survivability limits.

5. Standard CMOS TTL interface, latch-up will occur if logic

signal is applied prior to power supply

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.
