Title: how to run qpss for mixer+divide by 2
Post by silentgun on Mar 29^th, 2008, 8:06am

hi, all
I recently design mixer. for accuracy I added LO circuit associated with mixer which included divide by 2 and LO buffer.
when running qpss, I met problem.
For LO frequency 200M, vco frequency would be 400M.
but in qpss settingup form, 200M component was not available.
how could I get the downconverted frequency which should equal fin-200M

thanks

Set "freqdivide" parameter as two.
