Compact Reflection-Type Phaser Using Quarter-Wavelength Transmission Line Resonators
Weiwei Liao, Qingfeng Zhang, Yifan Chen +1
A compact reflection-type phaser composed of quarter-wavelength transmission line resonators interconnected by alternating K- and J-inverters is proposed. A design method is also p…
Coupling Matrix Synthesis of Nonreciprocal Lossless Two-Port Networks using Gyrators and Inverters
Qingfeng Zhang, Toshiro Kodera, Shuai Ding +1
A coupling matrix technique is presented for the synthesis of nonreciprocal lossless two-port networks. This technique introduces complex inverters to build the nonreciprocal trans…
Planar Reflective Phaser and Synthesis for Radio Analog Signal Processing (R-ASP)
Lianfeng Zou, Qingfeng Zhang, Christophe Caloz
A planar reflective phaser based on an open-ended edge-coupled-line structure is proposed. This phaser is the first reported phaser that combines the benefits of high resolution, i…
Enhanced-SNR Impulse Radio Transceiver based on Phasers
Babak Nikfal, Qingfeng Zhang, Christophe Caloz
The concept of SNR enhancement in impulse radio transceivers based on phasers of opposite chirping slopes is introduced. It is shown that signal to-noise radio (SNR) enhancements b…
Hybrid-cascade Coupled-Line Phasers for High-resolution Radio-Analog Signal Processing
T. Paradis, S. Gupta, Q. Zhang +2
A hybrid-cascade (HC) coupled-line phaser configuration is presented to synthesize enhanced group delay responses for high-resolution Radio-Analog Signal Processing (R-ASP). Using…
Generalized Coupled-line All-Pass Phasers
Shulabh Gupta, Qingfeng Zhang, Lianfeng Zou +2
Generalized coupled-line all-pass phasers, based on transversally-cascaded (TC), longitudinally-cascaded (LC) and hybrid-cascaded (HC) coupled transmission line sections, are prese…
