I am having bit of trouble simulating coaxial resonators in ADS.

My resonator specifications are;
Size: 6x6
Impedance :6.02Ohm
Freqency: 460MHz
Er :98
Q :330
Plating : Silver

The values I entered on TLPSC;
Z : 6.93Ohm
L :0.648 in
K :98
A :1.2 dB/m
F :460MHz
TanD : 0.00
Mur :1
Tan M : 0.00
Sigma : 0

I have used the Transtech application guide to calculate this values. http://www.trans-techinc.com/appnotesPDFs/No1009.pdf Can some one confirms these are correct.

I am not getting enough notch depth in my simulation using the above TLPSC model.

No one else has this question

When I run a 2 port s-parameter simulation using your values the S21 notch @920 MHz is -60 dB which seems pretty respectful to me. If you still feel this is not enough I recommend revising the attenuation parameter. For example if I make A=0.12 dB/m the notch becomes -80 dB.

I hope this helps.
