General Description

SAC3309 covers 3.4 to 4.2 GHz as a 6-bit GaAs MMIC phase shifter die. It reaches 1 degree RMS phase error with 5.625 degree steps across 360 degrees, and insertion loss is 5.5 dB.

Over all states, amplitude ripple is about ±0.5 dB; worst case phase error falls between -5 and +2.5 degrees. Both ports measure 1.5:1 VSWR. Drive it with 0/+5 V logic and keep RF input under +18 dBm. The 3.8 x 1.24 x 0.1 mm die lands in upper S-band and C-band radar and SATCOM front ends.
