This paper introduces a design of bandpass NGD circuit with 3.6-GHz centre frequency. The NGD passive topology consists of parallel resistance associated with an open-ended microstrip stub. The S-matrix and group delay (GD) model of the topology are established. A microstrip proof of concept is designed and simulated to validate the theoretical approach. The simulated circuit operates with -0.34 ns NGD around 3.6 GHz centre frequency over 0.32 GHz bandwidth and only 3 dB attenuation loss. This NGD circuit can be useful for the improvement of phase linearity and GD equalization of future 5G microwave devices.
