The present invention relates to a negative group delay filter. Disclosed is a negative group delay filter which has a less sensitivity to a temperature change, an improved input/output return loss, and an extended bandwidth, by configuring a negative group delay circuit (NGDC), using a dispersed transmission line which has a signal attenuation characteristic of band stop filter (BSF), and negative group delay (NGD) time, in order to address problems regarding negative group delay (NGD) operating frequencies bandwidth, a huge insertion loss, and negative group delay time control, caused by previous inventions related to negative group delay circuit implemented by circuits using an idea of resonant circuit. |
