fundamental frequency problem in HB

yefJ over 6 years ago

Hello, i have tried to simulate a mixer with LO=303ps=3.3GHz Vpulse RF=6.6GHz VSIN as shown bellow.

and i defined HB to see the combinations of these tones, but it says "The source V6 couldn't find matched freq"

The HB definition , the error and the full the attached full LOG are shown bellow.
Where did i go wrong?
Thanks

Hardly surprising, because 1/303p is not 3.3G. It's slightly above that and so they are not going to match. Enter the frequency on the hb form as 1/303p rather than 3.3G - i.e. make it compute 1 over the actual period of the pulse source - then they will match.

Regards,

Andrew.
