Accuracy Study for a Moderate Production Quantity of Reciprocal Ferrite Phase Shifters

A moderate quantity of X-band dual-mode reciprocal, latching ferrite phase shifters has been built and tested in a computer-controlled station. Ensemble phase shift distributions and statistics have been investigated using stored test data. Variation with frequency is small over the design band, and the phase state dependent data show the effects of curve-fitting computed during testing.
