A tunable balanced phase shifter with wide operating bandwidth
International Journal of Microwave and Wireless Technologies, 2023AbstractA wideband tunable balanced phase shifter is achieved by utilizing varactor-loaded coupled lines (VLCLs)-embedded multistage branch-line structure. The tunable phase shift with low in-band phase deviation is attributed to the regulation in phase shift of the VLCLs and the horizontal microstrip lines in series. The wideband differential-mode (DM)

Compact Tunable Phase Shifters on Screen-Printed BST for Balanced Phased Arrays
IEEE Transactions on Microwave Theory and Techniques, 2011Two designs for compact continuously tunable phase shifters are presented employing integrated ferroelectric varactors based on screen-printed barium-strontium-titanate thick film. The circuits are based on left-handed transmission-line topologies that allow to realize very compact modules.

Magnetic balanced phase shifter for polyphase supply
IEEE Transactions on Magnetics, 1974A novel method of balanced firing of thyristors used for polyphase supply is presented. The phase angles of the polyphase voltages are shifted simultaneously by controlling a phase shifter of a single phase. A simple feedback circuit including a saturable core and an integrator plays a key role in this balanced phase shifter.

An inductorless electrical-balance 360° phase shifter for 0.5–1.15GHz in 0.18μm CMOS
2015 10th European Microwave Integrated Circuits Conference (EuMIC), 2015This paper presents an integrated phase shifter based on electrical-balance operation. The phase shift of the circuit is set through the difference in impedance between two on-chip tunable impedances. Each impedance consists of a parallel combination of a tunable resistor and a tunable capacitor.

Balanced Wideband Phase Shifters With Wide Phase Shift Range and Good Common-Mode Suppression
IEEE Transactions on Microwave Theory and Techniques, 2019This paper proposes a class of balanced wideband phase shifters with wide phase shift range and good common-mode (CM) suppression. Both the balanced filtering units in the reference and main branches consist of horizontal half-wavelength branches and vertical quarter-wavelength loaded stubs but with dissimilar sizes.

Balanced Wideband Phase Shifters With Good Filtering Property and Common-Mode Suppression
IEEE Transactions on Microwave Theory and Techniques, 2019In this paper, a class of balanced wideband phase shifters with good filtering property and common-mode (CM) suppression is proposed, synthetically designed, and implemented. Unlike the conventional coupled-line reference branch one, the proposed balanced phase shifter has its T-shaped structure in both of main and reference branches, so as to achieve ...
