Phase shifters are used in conjunction with Linear Feedback Shift Registers and Cellular Automata in order to impose sufficient channel separations on the bit sequences produced by their successive cells. The aim is to reduce structural correlations and/or linear dependencies that are problematic for pseudorandom and pseudoexhaustive built-in test ...

Arbitrary phase shifters with decreasing phase
2015 38th International Conference on Telecommunications and Signal Processing (TSP), 2015This paper describes a new class of the versatile network elements for analog signal processing; two-ports with frequency dependent phase shift which starts with arbitrary value and tends towards different but still arbitrary value. Speaking in terms of the complex frequency response plotted in polar coordinates the characteristics can connect any two ...

Phase shifters for dielectric guides
IEE Proceedings H Microwaves, Antennas and Propagation, 1991A phase shifter has been designed to give a constant phase over the octave bandwidth 70-140 GHz in dielectric guide. The phase shifter was designed for use in a multistate reflectometer in dielectric guide, though other applications are possible. The multistate reflectometer required two less power meters than a previous six-port reflectometer.

Monolithic Phase Shifter Study
1987Abstract : Modeling and testing of monolithic coplanar waveguide (CPW) phase shifters using both optical and Schottky-contact control techniques have been performed. Simulation work on a periodically illuminated structure has been completed, showing that some improvement in performance may be possible, although with a reduction in frequency bandwidth ...

IEEE Transactions on Microwave Theory and Techniques, 2007
A method with clear guidelines is presented to design compact planar phase shifters; with ultra-wideband (UWB) characteristics. The proposed method exploits broadside coupling between top and bottom elliptical microstrip patches via an elliptical slot located in the mid layer, which forms the ground plane.

Broadband Fixed Phase Shifters
IEEE Microwave and Wireless Components Letters, 2011A method to design planar and compact phase shifters with broadband characteristics is presented. It utilizes broadside-coupled microstrip-coplanar waveguide, and thus the proposed devices can be fabricated using the simple and cheap double-side printed circuit boards. The method is used to design 60° and 90° phase shifters.
