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 :
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
How many resonators do your 3D object has as a cavity filter?

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
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
hi, how to calculate band width rejection in cavity filters(combline &interdigital case )? thank you
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
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
combline filters are transmission line filters. cavity filters are totally hollow areas enclosed by metal and have standing wave patterns. Power is coupled in and out by irises in the case of waveguides and electric or magnetic probes in the case of coaxes.
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
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
Hi,all! Merry Christmas! I now have troubles in designing a hopping was made of a fixed combline cavity and a capacitors matrix which fixed at the end of the bar.Each branch of the matrix will decide an available center frequency of the filter.Each branch is mainly made of a PIN diode and a high Q capacitor. Now, Mr Problem come
Not sure if you meant coaxial combline filters or empty cavity type. They are almost always used interchangebly. Either case, the example presented using HFSS should help.
I want to know the difference at performance and phyical size between combline resonators with ground plane between resonator posts and reactangular cavity resonators without resonator posts in the cavity. Thanks!
