Three problems encountered in latched digital phase shifters controlled by partial magnetization, are dealt with. 1 The efficiency of flux transfer and the possibility to add flux bits. Experimental data and a theory in agreement with these data are presented. 2 The control of rf-fields in a ferrite loaded guide to achieve a a high differential phase shift per loss, and b a linear relation between differential phase shift and transferred flux First results obtained with slab line and waveguide type phase shifters are given. Models to analyze the possible modes in these devices are discussed. 3 The onset of non-linear losses at a certain magnetic rf-field strength. In a coaxial line completely filled with ferrite a TEM mode exists. The magnetic field can easily be calculated from the incident power. Threshold field strengths are given for various ferrites.
