General Description

SAC3308 brings 6-bit digital phase control to Ku-band: it is a GaAs MMIC die covering 14 to 18 GHz with a 5.625 degree LSB. RMS phase error is 3 degrees and insertion loss is 10 dB.

Amplitude stays within ±0.5 dB across the 360 degree range, and peak phase error spans -7 to +2 degrees. VSWR is 1.7:1 in, 1.5:1 out. It uses 0/+5 V control and measures 3.8 x 1.24 x 0.1 mm. In Ku-band SATCOM and radar beamformers, plan a gain stage to cover the 10 dB loss.
