Description
M/A-COM's AT-273 is a GaAs FET digital attenuator
with a 16.0 dB minimum step size and a 32 dB total
attenuation range. This attenuator and integral TTL driver
is in a hermetically sealed ceramic 16-lead surface mount
package. The AT-273 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.
Environmental screening is available. Contact the factory
for information.
