RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Question about µWave's fcmax - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. If the folks at phpBB would release a version with integrated sign-in from the major social media platforms, I would resurrect the RF Cafe Forums, but until then it is probably not worth the effort. Regardless, there are still lots of great posts in the archive that ware worth looking at.

Below are the old forum threads, including responses to the original posts.

When I simulate a combline fiter in µWave
cutoff freqency=20ghz, errors occurred and information displayed as below:

ERROR 1: Internal error in project [Combline.circuit_1]: Error for structure spres_31: critical order is exceeded by 166.66666667%
INFO in project [Combline.circuit_1]: Structure can be analyzed up to fcmax = 12.00000GHz
ERROR 1: Internal error in project [Combline.circuit_1]: *==> Execution Terminated!
ERROR 1: Internal error in project [Combline.circuit_1]: Error in subroutine destroy_qres: unable to (de)allocate memory
Program terminated with an error! ---Error occurred at f=1.800000 GHz [1.point]! Calculation time (0:00:00)

In order to get precise results, how can I modify the "fcmax" ?
Thanks in advance!
