The SuperApex SAC3406ASPQ4 is a broadband 6-bit GaAs digital attenuator MMIC chip. Covering DC to 12GHz, the insertion loss is less than 2.5 dB typically. The attenuator bit values are 0.25dB, 0.5dB, 1dB, 2dB, 4dB and 8dB for a total attenuation of 15.75dB. Three TTL 0/+5V inputs are used to select each attenuation state.
