hairpin 1296mhz
I am ham radio YO3HCV and currently working on 1296 MHz transverter project .
I try to design some filters on FR-4 material but my knowledge in microstrip’s are so poor … on google I found some nice programs like Sonnet and Parfil but of course, not for free. Does any body know where to find a full version of these, or at least a functional demo ?!?
For example with Sonnet, when I try a hairpin filter, ask me to register…I register but program needs a lot of memory ?!?... and in demo I cannot do nothing but see his nice examples. And with Parfil, I cannot design on FR-4 …lol… the only demo it has…
Can anybody help ?
Best regards,
YO3HCV, Eddy
