## design a bandpass filter (4.4-5Ghz) with DGS

Hello! I´d like to design a bandpass filter (4.4-5Ghz) with DGS. I´ve read some papers about DGS. In none paper i´ve found how to calculate the dimensions for the DGS. Are they only guessed and simultated or is it possible to calculate them easily? I´m not looking for an accomplished design - I wan´t to recognize how to (...)

## Looking for a waveguide filter book (illustrating design of)

Hi, I am interested in learning more about designing a microwave cavity filter that utilizes a structure quite similar to a commonly found waveguide band pass filter using shunt inductance coupling (to couple resonators) (see and ). However, the structure I am interested in also contains a post centered between the coupling irises with

## Complex bandpass filter design

I will design complex bandpass filter(Active RC filter). Usually, I use filter Solution Program for designing filter. But, I can't find complex filter in filter Solution Program . Please let me know how to design it. (...)

## Process variation for a complex bandpass filter

Hi! I am doing a design of a complex bandpass filter. But the variation of the process is a big question. And i can't find the solution. Thanks in advance! Added after 2 minutes: oh, the filter structure of my design is active RC.

## Cavity bandpass Filter design

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 in advance

## lengths in bandpass filter

If you are talking about microstrip interdigital filter (this is smallest and least expensive realization), then 0.402" is good length for such filter. I include screen shoot from quick design that shows all dimension and S21 and S11 plots. This is schematic simulation only. EM simulation will provide response shifted down about 10% in (...)

## dielectric or strip line

hi to all i want to design a bandpass filter in c band( IEEE) i.e 4 to 5 ghz what type of filter is suitable either dielectric resonator filter or stripline filter. can i design with microstrip lines for this purpose, any replies plz thank you u can do it in both (...)

## need free links for the filter

hi i want to design combline bandpass filter with round rods is there any free software links for this plz post here thank you

## designing a bandpass loww freq. filter

The frequency is low. It sounds to me that your BPF design is used in ADSL / VDSL. Right? You can reference to some filter design book.

## Designing a capacitor-top coupled bandpass filter

Hello I am new here and I hope to get help for my assignment: Question ? design a Chebyshev three-resonator, capacitor top-coupled, constant-k bandpass filter centered at 1MHz, with 1 dB ripple and a 100kHz, 3 dB bandwidth. The source and load resistors are 1.5kΩ and available inductors have a quality factor of 60. We just

## choise of analog filter: system level design

hello all, In big chain system level design where RF BPF, IF BPF, and LPF are required. What is the choise of filter? which filter I should select for my design? which on is good for Bluetooth and WLAN and WCDMA? which is good choise butterworth or chebyshev?

Hello mallelauma, Attached are the requested documents on Combline filter design... design Equations for Tapped Round Rod Combline and Interdigital bandpass filters ---manju---

## round rod cavity filter design

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

## How to be RF designer??? tips plz help

Hehe, i see someone is developing RF circuits in the home shack. Just a little comment: Amplifier 2 Ghz ... very crappy design bandpass filter 780 MHz ... sloppy, but might even work okay Lowpass filter 400 MHz ... very crappy design

## Sigma Delta converter : NTF synthesis

Hi... I used the Schreier Sigma Delta toolbox to design my NTF of order 3... How do I realize the loop filter in an easily implementable way!!! I mean without using CIFF or CIFB architectures..? Moreover, I am trying to do the bandpass modulator for GSM as well with order 4... In which case, my sampling frequency is four times 70M (...)
