Digital Attenuator
MACOM'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 are required. Typical
applications include dynamic range setting in
precision receiver circuits and other gain/leveling
control circuits. Environmental screening is
available. Contact the factory for information.
