Description
M/A-COM’s AT-232-PIN is a GaAs FET 4-bit digital
attenuator with a 2 dB minimum step size and 30 dB
total attenuation. This attenuator is in a hermetically
sealed ceramic 16-lead surface mount package. The
AT-232-PIN is ideally suited for use where accuracy,
fast switching, very low power consumption and low
intermodulation products are required. Typical appli-
cations include dynamic range setting in precision
receiver circuits and other gain/leveling control cir-
cuits. Environmental screening is available. Contact
the factory for information.
