ADS: Impedance Inverter K ?

Hello
Where i can find The Inverter Impedance K on ADS to design a circuit equivalent for a MICROWAVE band pass filter?

Thank you

I've never been able to find a K inverter block, when I want an ideal K inverter I build one from ideal capacitors or inductors, like so:

Where the characteristic impedance K is given by K = w*L where w is the angular frequency.

I make the inductance a variable equal to K/w so the value of K becomes frequency invariant (if you require that).

hello Kthackst
Thank you for your help
You can use The matrix ABCD (In ADS use :Chain)


Best regards
