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.
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.
Electrical Specifications: T
1. All specifications apply when operated with bias voltages of +5V for Vcc and –5.0V for Vee.
2. This attenuator is guaranteed monotonic.
