Digital Attenuator
15.5 dB, 5-Bit, TTL Driver, DC-2.0 GHz
Features
• Attenuation: 0.5 dB Steps to 15.5 dB
• Temperature Stability: ± 0.18 dB from –55°C
• Low DC Power Consumption
• Hermetic Surface Mount Package
• Integral TTL Driver
• 50 Ω Nominal Impedance

Description
M/A-COM’s AT-283-PIN is a GaAs FET 5-bit digital
attenuator with a 0.5 dB minimum step size and 15.5
dB total attenuation.
TTL driver is in a hermetically sealed ceramic 16
lead surface mount package.
ideally suited for use where accuracy, fast switching,
very low power consumption and low intermodula-
tion products are required. Typical applications in-
clude dynamic range setting in precision receiver
circuits and other gain/leveling control circuits. Envi-
ronmental screening is available. Contact the fac-
tory for information.
