The PS-85M4G-9B-SFF from Quantic PMI (Planar Monolithics) is a Digital Phase Shifter that operates from 0.085 to 4.0 GHz. It has the capability of phase-shifting from 0° to 360° with a phase-shift error of ±10°. This phase shifter has an insertion loss of less than 13 dB and a switching speed of less than 500 ns. It has a 9-bit TTL control with nine logic input lines that allow 512 discrete values of phase and an amplitude error of ± 1.0 dB. This phase shifter consists of an analog phase shifter and a digital-to-analog converter. It requires a DC supply of +15 V consuming 250 mA of current or -15 V consuming 20 mA of current. This phase shifter is available in a package that measures 4.95 x 3.38 x 1.00 inches and has SMA female connectors.
