Analog/Digital Ferrite Phase Shifter for Phased Array Antennas
IEEE Antennas and Wireless Propagation Letters, 2010A planar ferrite phase shifter is designed to exhibit simultaneous analog and digital phase tuning properties. Analog phase control is achieved by using an external magnetizing field, and digital phase change is realized by switching the phase shifter operation from microstrip to waveguide mode.

High Precision Digital Based 3.8GHz Phase Shifter
2015 IEEE 18th International Symposium on Design and Diagnostics of Electronic Circuits & Systems, 2015The paper reports a highly repeatable 10-bits 3.8 GHz phase shifter implemented in a standard 0.35 µm SiGe technology for high precision applications. The prototype principle of operations and design are thoroughly described and demonstrated. The generated 0.35° phase step exhibits a rms error lower than 0.32°, mainly determined by the PLL inserted in ...

Multicolor digital holography with an achromatic phase shifter
Optics Letters, 2002Multiwavelength recording and reconstruction of a three-dimensional object are realized by use of phase-shifting digital holography. Red, green, and blue lines emitted from a white-light He-Cd laser are used for one-step recording of the complex amplitude of the object with a color CCD camera, in which a phase shift is introduced with an achromatic ...

Instruments and Experimental Techniques, 2007
A digital phase shifter with linear phase-shift variations with a π/N step, where N is the overall division factor of used frequency dividers, is described. The device is easy to realize and intended to easily set and change a phase-shift step, carrying out the reverse (manual and automatic) phase change with a preset rate.
