Dear friends,
I've downloaded and tried to install all the versions available from PDL-2.4.1 to PDL-2.4.3 in Windows XP but none of them successful.

Could anyone who successfully installed it on your PC using the same OS share with me your experience...
s-parameters mom
Dear Jian:
Thanks a lot for your information. Is your thesis named as "Electromagnetic Modeling of Microstrip Circuit Discontinuities and Antennas of Arbitrary Shape" ?
Really unfortunate that I googled for it in vain for quite a long time.
Again. Thank you just the same...
how to calculate s parameters
EM solvers like HFSS, CST MWS, IE3D, ADS Momentum etc can easily calculate multi-port S-parameters over a large frequency range. Does anyone implemented or knows the detailed similar algorithms to extract the S-parameter using some numerical methods like RWG based...
Dear all:
I've tried to google for the LED(plastic optical fiber light sources) modeling methods or spice models in the past few days and found nothing useful. If you have relevant information or experience, would you please kindly share with me?
BTW: I'm trying to find some peripheral/line...
Hi,
Anyone here can help to answer my questions regarding "password" and "gap" I raised in my last post? (just one-level above this post).
Thank you in advance.
Best regards,
skin effect rdc
Hi, rautio:
Yeah! I do agree with you that this kind of explanation is kind of "unconventional" if it is really the case and the developer of this tool do not consider it as a "bug". Actually I contacted their support engineer and they do not give me a good answer at that time...
Hi, francx:
According to my understanding,when people deal with experiment data by pre-processing the data with a scale of log, they make nonlinear data linear to facilitate analysis. Regarding the BER-sensitivity theoretical background, kindly search the maxiam website **broken link removed**...
pure ac resistance
Hi, Rautio:
I totally agree with you that the real-life(phycially true) R(ac) is not separable for a specified object. The reason I quote "Rdc+Rac" considered as R(ac) by someone is only a way to facilitate the understanding from a pure "mathmatica" point of view. Just like...
effect of resistance in ac
Dear all:
I've ever encountered the same problem long time ago when I used the Q3D version 5 to extract RLC of a 3D structure. It gives me Rac<Rdc which is physically not true. Till today, I still can not understand why is that so if it's not a bug of the software...
Dear all:
Out of curiosity, I registered and downloaded the design kit. However, I found that a password is needed to access the designer project. Anyone knows what is that? If I do not use the foundary of UMC but have the commercial license of both HFSS and Designer, who should I approach for...
Hi, magneto_cool:
Your suspect is right as the reported Q factor of spiral inductors on Si substrate with inductor value of several nH is absolute less than 20 even with a lot of Q-boost techniques included(such as thicker metal, etched substrate, high-resistivity substrate etc).
Your...

Hi, IanP:
Thanks a lot for your help!
It would be better if you can give more details on this figure such as suitable parts(part number) of the transistor.
Actually, after intesive searching on the Internet, I also found similar circuits that used Philips BSNxx series...
