## Interdigital Bandpass Filter - Design procedure (Lancaster)

Hello, I am following the design example of an interdigital filter with symmetric coupled lines as given in microstrip filters for RF-Microwave Applications (Lancaster), page 141. I managed to calculate the characteristic impedances in even and odd-mode and, consequently, the coupling coefficients. My struggle is to calculate the spacing (...)

## Component for designing microstrip combline bandpass filter

I never cease to be amazed at the variety of filter topologies hiding within ADS... I haven't used this one before! I believe the one you're looking for is the "CMfilter" ( ), which hides in the "Passive circuit DG - microstrip circuits" component palette.

## Is it common to make microstrip bandpass filter elements thinner to overcome loose Er

Wh y do you think thinner would decrease effects of variation? Variation will still exists. But i hope that thinner coupled lines have a wider passband. Simulation shows that with some etching errors of 0.1mm with a line width of 1mm gives more than -10..-20dBm s21 attenuation (beacuse out of passband), and 0.4mm coupled line gives

## Can microstrip banpass filter sizes be halved for f/2 freq and work without cutting?

If bandpass filter for frequency F is successfully tuned, so PCB layout size after fabrication is final lenght that works without cutting or adding copper, can the same filter for halve F/2 or double F*2 frequency be made just by halving/doubling microstrip lengths in layout? Or there is a possibility, that this thing scales (...)

## Bandpass filter design approach

Accurate filters are not constructed with LC elements at that frequency due to their tolerances,standard values,temperature effects and non-ideal models.. Also, board and its prasitic effects will shift the filter characteristics. You can build a microstrip filters on a PCB boad by EM simulating and then doing optimization.
