General Description

SAC3402A is a 6-bit GaAs MMIC digital attenuator die for DC to 6 GHz, stepping in 0.5 dB increments up to 31.5 dB total. Insertion loss is 2.5 dB and RMS attenuation accuracy is 0.8 dB.

The bit weights are 0.5, 1, 2, 4, 8 and 16 dB, selected with 0/+5 V LVTTL logic. Both ports run 1.4 VSWR, input power is rated to +22 dBm, and the passivated die is 1.78 x 1.21 x 0.1 mm. It handles gain control in cellular infrastructure, EW receivers and test sets.
