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 nonlinearly on some substrate? I do not worry about losses too much, but about center frequency.
