Design Combline filter

I want to design Design combline. I practised followed the A Practical Design of Lumped, Semi-Lumped and Microwave cavity Filters (Dhanasekharan_Natarajan'book) with Hfss Software but i don't know how to turning length of skew to achieve results? Please help me. I found the document :

Cavity filter - how to calculate coupling factors from S-parameter simulation?

Hello everyone, I am trying to design combline cavity filters according to Puglia 1 Puglia 2. I can calculate lowpass g-goefficients and coupling factors for my

simulation of a 3D cavity filter

HFSS can do the job of a 3D filter. But for 5 resonators, tuning is required. What kind of resonator configuration do you have? Is it combline? Waveguide? or something else?

VERY GOOD COLLECTION OF HFSS 10 PROJECTS

Hi All I'm looking for HFSS waveguide filter examples eg combline, interdigital, cavity etc Does anyone have working HFSS projects they are willing to share?? All the best Ody :)

Sparameter to Coupling Curve

could use some assistance or guidance on a filter design I am working on. We design our combline and cavity filter via a coupling matrix. The coupling between resonators are given in coupling bandwidths. A 2 port model is created in HFSS then we extract the sparameters from HFSS then import it into a circuit simulator. We lightly couple each port

Length calculations of interdigital and combline rod filters

hi to all, any one tell me that the length calculations for the both interdigital and combline round rod cavity filters are same or not?(becas it only depends on frequency ) thank you

How to calculate band width rejection in cavity filters?

hi, how to calculate band width rejection in cavity filters(combline &interdigital case )? thank you

Wall spacing for interdigital and combline filter

hi toall any one tell me that end wall spacing is same or different for both interdigital and combline filter?(this is in case of cavity filter with round rods as resonators) thank you in advance

What is meant by cross coupling in the cavity filter ?

hi waht is mean by cross coupling in the cavity filter ? and also any one the idea about the coupling band width in the cavity combline filter plz ans any 1. thank you

Q0 of cavity rezonator

It depends on what kind of resonator you have. Normally, metal cavity, such as combline resonator or an air coil inductor, has a higher unloaded Q at higher frequency, while dielectrics has a higher loss at higher frequency thus lower Q0. Hello I have Qo on cavity rezonator at frequency f1. what is the Qo at frequency f2? f

software to design cavity bandpass filters and duplexers

Hi, does anyone know of an appropriate software to simulate cavity filter and cavity duplexer response. I am curious if the software can tell us the cavity diameter and spacing in case of interdigital and combline cavity filters

Question about combline cavity diplexer design

Hi I am designing a combline cavity diplexer and I wonder if there is a way to align "tune" the resonators, and can I use power combiner at the output to see the response for the two filter at the same time I apriciate any help Cheers
