Hello edaboard community,
I am desingning a simple matching network and I have a few questions about the implementation of it on a PCB. The matching network consists of a few passive components, transmisison lines and vias. I am confused whether to use solder resist or not. Do they actually effect the characteristic impedance of the transmission lines? I have read a lot about microstrip transmisison line none of them talks about the effect of the solder resist. By the way the matching network is designed to work at 2.4GHz. Does anyone know solder resist has any significant effect on the frequency characteristics on circuit?
