General Description

SAC3404 is a broadband 2-bit GaAs digital attenuator MMIC chip. Covering DC to 12GHz, the insertion loss is less than 2.2dB typically. The attenuator bit values are 10dB and 20dB for a total attenuation of 30dB. Three TTL 0/+5V inputs are used to select each attenuation state.

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