W-Band, 75 – 110 GHz, Direct-Reading Precision Phase Shifter

528W/387, Accuracy ±5°, Insertion Loss 2.0dB, Power Handling 0.6 Watts


Mi-Wave’s 528 Series Direct-reading Phase Shifters provide highly accurate measurement of phase shift over each full waveguide band from 26.5 to 170.0 GHz. They feature low VSWR, low insertion loss, and low insertion-loss variation due to the rotation of the phasing section.

The 528 Series Direct-reading Phase shifters offer a convenient, frequency insensitive method of measuring phase shift. These devices are useful in waveguide systems where the phase and amplitude must be measured or adjusted independently. Typical applications include bridge circuits, phased arrays, and interferometers.
