Hello,

There is a free tool from Nuhertz Filter solutions for Filter design...
& also a 30 days full version trial license also available it even as the dxf & sonnet export for Planar Hairpin resonator Transmissionline filters...

**broken link removed**

Then finally use the Sonnet Lite free version to validate, see here some examples

A 9th order Hairpin bandpass filter with 0.5 dB passband ripple is required for -60 dB stopband attenuation at 900 MHz (lower cutoff -10 % ) and 1540 MHz (upper cutoff +10 %).
