Impedance Inverters (K) or Admittance Inveters (J)

In designing filter, normally we will have couplings such as Impedance Inverters (K) or Admittance Inveters (J). How to realise these Ks or Js in practical? Thank you

You can realize J or K inverters using capacitive gaps or coupled lines or simply lampda/4 T.Ls .

For more information please refer to Microwave Engineering 2nd edition chapter 8,pages 469 474-485 490-493 .

Dear ieropsaltic, thanks for the advice. Since i am going to realise my design into co-axial resonator filter, is it i'm able using the same method as per mentioned by Pozar? Do you have any info regarding coaxial resonator filter design? thks again
