Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts. maniana Post subject: Harmonic Balance simulation Unread postPosted: Fri Mar 18, 2005 10:55 am Offline Lieutenant Joined: Fri Mar 18, 2005 10:47 am Posts: 1 Hi, I need to sumulate a mixer (Gilbert cell). When I run Harmonic Balance simulation everything is ok if I put different LO and RF frequencies. In my design I use LO=RF and I am interested in the DC component / performance of the mixer. The problem is that when LO=RF the simulator returns some rubbish results or nothing at all. I tried that on Agilent ADS and Microwave Office. Any idea what I am doing wrong? Is it some kind of limitation of the Harmonic Balance Simulation? How to overcome this problem? Thanks, Przemek Top Profile Guest Post subject: Unread postPosted: Sun Mar 20, 2005 9:48 am Assuming that tthe model you are using is OK ( non linear model), then you can try and increase the number of harmonics of the simulator, although this may not help since the expected output should be a DC signal with perhaps leakage tones from the RF and LO ports. Is the simulator giving you a convergence error? Posted 11/12/2012 | ||||||
