General Description

   SAC3401 is a broadband 3-bit GaAs digital attenuator MMIC chip. Covering DC to 4 GHz, the insertion loss is less than 0.7 dB typically. The attenuator bit values are 0.3dB (LSB), 0.6dB, 1.2dB for a total attenuation of 2.1dB. Three TTL +5/-5V inputs are used to select each attenuation state.

The chip offers full passivation for increased reliability and moisture protection.
