General Description

Working over 5 to 6 GHz, SAC3306Q5 is a GaAs MMIC 6-bit digital phase shifter in a 5 x 5 x 1.2 mm QFN. Its LSB is 5.625 degrees, RMS phase error is 3 degrees, and insertion loss comes in at 6 dB.

Match is a strong point here: input VSWR is 1.17:1 and output 1.12:1, which helps when several are cascaded. Amplitude shifts ±0.8 dB over the states, and control uses 0/+5 V logic. Typical sockets are C-band beamforming, EW and phase cancellation boards.
