i totally agree with u. the best way to do it is put together the ckt prototype n try to optimize it on bench using different dioides with different recovery n transistion time. genesys new version 2004 has one additional module called as AMk (advanced modelling kit) using Verilog A. i...
u can also do it with network ana. just measure inserstion loss and return loss on smith chart. return loss will tell u the impedance of the line. if the rerunloss is as close as possible to center of the smith chart its a 50ohm line
wat do u mean wats the procedure take a look at microwave filter text by G.Matthaie and genesys has flter synthesis which gives u the layout ofthe filter. u cant learn everyhting form this msg board try exploring genesys
Re: what is the best substrate for a microstrip power divide
a good material at high freq is RT 5880 or materials from Taconic like RF-35. RT 5880 has low tand=0.00019 n is very stable at high freq works very well in Ku band.
many simaltion packages like ansoft designer, genesys have built in transmission line calculators whic give u the widht of 50ohm line or any impedance line at any given freq. or u can dload this rf calculator from www.milmega.co.uk
