Features
• Attenuation: 16.0 dB Steps to 32 dB
• Low DC Power Consumption
• Hermetic Surface Mount Package
• Integral TTL Driver
• 50 ohm Impedance
• Temperature Stability: ±0.18 dB from -55°C to
• Tape and Reel Packaging Available

Description
M/A-COM's AT-273-PIN 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-PIN is ideally suited for use where accuracy,
fast switching, very low power consumption and low
intermodulation products
applications include dynamic range setting in
precision receiver circuits and other gain/leveling
control
available. Contact the factory for information.
