Anyone know which is better on cavity filter design? I wonder the well-known company major in cavity filter use which,or some other software else?
Hi all , I'm looking for the design formulas for a cavity filter . I want to build a cavity filter for 408MHz for radio astronomy purpose . The idea is to place an adjustable tube inside another tube and working with coupling loops to form a cavity filter, just like (...)
A very good tool for cavity filter design is MWWizard from Mician. bye
For cavity filter design, now we only first simulate single cavity's resonance frequency, then caculate the coupling coefficient that determine the ires'width. I have seen some papers that introduce full cavity filter simulation using HFSS and CST,but I can't grasp the main idear, Can (...)
hi! everybody, I have cst and hfss.I want to design a microwave cavity filter,but I don't know which is better,cst or hfss?who can give me some suggest
A cavity filter used the cavity to provide a resonance, determined by the resonant mode in the closed filter. I'd start by looking at 1-Coupled resonator filter design. THis is older stuff, the relevant papers are probably from the 60's. 2-Coupling energy into and out of the (...)
hi, How to design a cavity filter? what are those waveguide cavity filters, coaxial cavity filters..... etc., if any Books for a learner to design and if any tutorials to do simulations using HFSS/CST MICROwave on this, helps a lot..... thanking (...)
dear sirs, I am now tring to design dielectric filters of about 2 G.with the bandwidth of 15MHz. the dielectric resonator's dimension is 40mm*40mm*33mm.and a dielectirc disc with height of 11 and diameter of 28mm is placed in the center. A hard foam is taken as a substrate with the same heght as the disc. but as a result, four D
I calculated the size of a TE101 mode caivty.and calculated the coupling coef between two identical cavities(2mm thick iris).then using the direct coupled method to got the size.but because the coupling coef is not very accuate so the simulated resoponse of the design is very poor.nearly cant see the filtering figure.I hope to use screws to tune
hi! I wanted to design a cavity filter.I had drafted the 3D model.(you can see the attachment of the post).First,I needed only design a fixed frequency filter.but later,my boss told me I must think more for redesigning it as a tunable filter.I planed to use a (...)
hi, i want to design a bandpass filter with round rods can any body help me to by sending design equations completely. thanks in advance
hi to all, i have to design cavity filter ............. but i dont know the info about these filters can any one guide me to do this plz thank you
You make the cavity and tuning screw out of materials with different coefficients of expansion. As one drifts one way over temperature, the other brings it back.
How many resonators do your 3D object has as a cavity filter?
If you have placed this cavity filter before LNA, the Noise Figure will be increased by the insertion loss of this cavity filter.Let say the insertion loss is 2 dB, overall Noise Figure of the system will start from 2dB.If you take the other receiving block into account, this Noise Figure will much higher.This is the error (...)
