General Description

SAC3403 is a broadband 6-bit GaAs digital attenuator MMIC chip. Covering 8 to 12GHz, the insertion loss is less than 3.8 dB typically. The attenuator bit values are 0.5dB, 1dB, 2dB, 4dB, 8dB and 16dB for a total attenuation of 31.5dB. Three TTL 0/+5V inputs are used to select each attenuation state.

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