Generalized Coupled-Line All-Pass Phasers [PDF]
IEEE Transactions on Microwave Theory and Techniques, 2015 Generalized coupled-line all-pass phasers, based on transversally-cascaded (TC), longitudinally-cascaded (LC) and hybrid-cascaded (HC) coupled transmission line sections, are presented and demonstrated using analytical, full-wave and experimental results. It is shown that for N commensurate coupled-line sections, LC and TC phasers exhibit N group delay

Cross-Coupled Line Bandpass Filter Based on Modified Parallel-Coupled Line Structure
Jurnal Elektronika dan Telekomunikasi, 2022 This paper presents a study of a narrow bandwidth of the bandpass filter with a cross-coupled line structure. This structure was designed to have a good filter selectivity with the transmission zeros and a simple design.

Directional microwave coupled-line couplers with high lateral coupling level
Доклады Белорусского государственного университета информатики и радиоэлектроники, 2021 Classic сoupled-line couplers with a high lateral coupling level by type of directivity are counterdirectional. Restrictions on their synthesis are imposed by the gap between transmission lines, which must be extremely small (tens of microns), the ...

Wideband Highly-Selective Bandpass Filtering Branch-Line Coupler
IEEE Access, 2022 This paper presents a novel design of a wideband highly-selective bandpass filtering branch-line coupler (FBLC). By integrating a coupled microstrip line, and an open-ended stub at each port of a single-section BLC, bandpass filtering characteristics ...

Design of Quad-Band Rat-Race Coupler for GSM/WiMAX/WLAN/Satellite Applications [PDF]
Radioengineering, 2021 In this communication, a novel quad-band rat-race coupler (RRC) is developed for GSM/WiMAX/WLAN/Satellite applications. A conventional RRC is converted to exhibit quad-band operation by using a quad-band microstrip-line (QBML).

Low-Noise Voltage Controlled Oscillator with Coupled Microstrip Lines of Different Lengths
Известия высших учебных заведений России: Радиоэлектроника, 2020 Introduction. Coupled two- or three-wire microstrip lines are often used to reduce a phase noise of voltage-controlled oscillators (VCOs). Unfortunately, the phase noise was not optimized depending on the lengths of a three-wire coupled microstrip lines ...
