A 37–40 GHz 6-Bits Switched-Filter Phase Shifter Using 150 nm GaN HEMT [PDF]
Nanomaterials, 2023 In this paper, we present a 6-bit phase shifter designed and fabricated using the 150 nm GaN HEMT process. The designed phase shifter operates within the n260 (37~40 GHz) band, as specified in the 5G NR standard, and employs the structure of a switched ...

Reconfigurable Josephson Phase Shifter. [PDF]
Nano Lett, 2021 Phase shifter is one of the key elements of quantum electronics. In order to facilitate operation and avoid decoherence, it has to be reconfigurable, persistent, and nondissipative. In this work, we demonstrate prototypes of such devices in which a Josephson phase shift is generated by coreless superconducting vortices.

An 8–18 GHz 90° Switched T-Type Phase Shifter [PDF]
Micromachines, 2023 This paper proposes a novel 8–18 GHz 90° switched T-type phase shifter (TPS). In contrast to the conventional TPS, the proposed TPS adds a compensation capacitance to greatly enhance the phase shifting capacity.

A Frequency-Independent Phase Shifter
Acoustics, 2023 In this paper, we utilise optimization methods to determine a frequency-independent phase shift such that two phase-shifted versions of a signal can be summed and the resulting amplitude spectrum is unchanged.

Design of Phase Shifters with Enhanced Selectivity and Miniaturized Size Using D-CRLH Resonator
International Journal of Antennas and Propagation, 2023 This paper proposes and demonstrates a novel filtering phase shifter with a compact size and good frequency selectivity using two dual composite right/left-handed (D-CRLH) resonators. Firstly, the study analyzes the D-CRLH structure to gain insights into

Long-Time Correlations in Single-Neutron Interferometry Data [PDF]
, 2020 We present a detailed analysis of the time series of time-stamped neutron counts obtained by single-neutron interferometry. The neutron counting statistics display the usual Poissonian behavior, but the variance of the neutron counts does not.
