Description
M/A-COM’s AT-213-PIN is a 4-bit, 1 dB step digital
attenuator in a hermetically sealed ceramic 16-lead
surface mount package. The AT-213-PIN is ideally
suited for use where high accuracy, fast switching,
very low power consumption and low intermodula-
tion products are required. Typical applications in-
clude dynamic range setting in a precision receiver
circuits and other gain/leveling control circuits. Envi-
ronmental screening is available. Contact the fac-
tory for information.
