Description

M/A-COM’s AT20-0106 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 ceramic 24-lead surface mount pack- age. The AT20-0106 is ideally suited for use where accuracy, fast switching, low power consumption and low intermodulation products are required. Typi- cal applications include dynamic range setting in precision receiver circuits and other gain/ leveling control circuits. Available with enhanced performance as fully hermetic version. Environmen- tally screenable as P/N AT-106-PIN.

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.
