A Ka-band reflection-type analog electrically controlled phase shifter [PDF]

AIP Conference Proceedings, 2017
In order to modulate the phase of RF signal continuously, a new miniaturized Ka-band analog electrically controlled phase shifter is presented. The phase shifter based on 90°directional coupler and parallel variable capacitance diodes(VCD) achieves matching circuit and shift phase, the circuit can gain wide range phase shift by changing the bias ...

A 25-50 GHz Digitally Controlled Phase-Shifter

, 2022
This paper presents the design and the implementation of a phase shifter based on cascaded reflection type phase shifters (RTPS). The RTPSs are based on a 90° hybrid coupler and varactors digitally controlled. By cascading the RTPSs the phase shift range

A wideband 360° analog phase shifter design [PDF]

, 2009
This paper proposes a reflection-type wideband 360° analogue phase shifter. The phase shifter employs a branch-line coupler circuit to achieve a wideband operation and a varactor-diode circuit to achieve a wide phase-shift range.

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Attitudes of cancer patients toward ctDNA‐based liquid biopsy for follow‐up

Molecular Oncology, EarlyView.
This mixed‐methods study explored cancer patients' experiences, knowledge, and preferences regarding ctDNA‐based liquid biopsy for follow‐up. Awareness of ctDNA was low and recall of previous liquid biopsy was imperfect, yet acceptance was high.

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

FEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...
