Bandpass NGD function design for 5G microwave signal delay synchronization application

This paper introduces a design method of simple bandpass (BP) negative group delay (NGD) topology. The fundamental specifications BP NGD function are defined. passive topology consists parallel resistance associated with an open-ended microstrip stub. properties and characterization respect to the constituting stub parameters established. validations performed theoretical calculated simulated GD, transmission reflection coefficients. circuit can be useful for improvement phase linearity GD equalization future 5G microwave devices.
