Description

M/A-COM’s AT-213 is a 4-bit, 1 dB step digital attenuator

in a hermetically sealed ceramic 16-lead surface mount

package. The AT-213 is ideally suited for use where high

accuracy, fast switching, very low power consumption and

low intermodulation products are required.

Typical

applications include dynamic range setting in a precision

receiver circuits and other gain/leveling control circuits.

Environmental screening is available. Contact the factory

for information.
