General Description

Covering 2 to 3.2 GHz, SAC3312A is a GaAs MMIC 6-bit phase shifter die with 5.625° resolution over 360°. RMS phase error is 2° and insertion loss is 8 dB.

State-to-state amplitude variation is ±0.5 dB, and VSWR is 1.4 on input and output. It is driven by 0/+5 V logic levels and the die is 3.82 x 1.24 x 0.1 mm. With S-band coverage it slots into weather radar and SATCOM beamforming front ends, usually behind a gain stage to make up the 8 dB of loss.
