    Using SRD Spice model to design comb gen using HB analysis

    Re: comb 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...

    what is the popular technique designing high pass filter

    hi could u be more specific about ur specs like cutoff freq, stop band attenuation, pass band attenuation, size... once the specs are clear u can chose the material

    Hello ,about the 50 ohms microstrip !

    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

    About hairpin filter design and simulation

    hairpin-filter 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

    what is the best substrate for a microstrip power divider ?

    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.

    Microstripline Widths at given frequency

    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 in theior download section

    Does HFSS operate better on Intel HT or AMD ?

    Re: HFSS On HT or AMD i have similar config but i use 1Gb of RAM which is dual channel 2 sticks of 512 mB ram on 3.2HT n it works just fine
