Description
M/A-COM’s AT-263-PIN is a GaAs FET 5-bit digital
attenuator with a 1 dB minimum step size and 31 dB
total attenuation. This attenuator and integral TTL
driver is in a hermetically sealed ceramic 16-lead
surface mount package. The AT-263-PIN 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.
mental screening is available. Contact the factory
for information.
