What an excellent presentation... Really clear and tells the viewer how he things through the design. Why could my college professors not be this clear???? Very good....

Easy to follow with practical equipment application. Kudos

Very clear and intuitive explanation. Thank you very much

Grate Video, and no complains about the Drawings.

this video is really rad dude thank you

You have a easy way to speack about complex issues... Even my self that dont speack english very well could understand your ideas... (ofcourse i repeated the videos a lot of times.. lol) Congratulatios guy!

Very helpful videos. Keep it up.

Many thanks, did most of my project using this

Late to the show but of course, enjoyed it just the same. Very interesting. My brain is playing catchup. Thank you 👍😁 SUBBED! ❤

Thanks for that. I learned something here.

Very informative. Great teaching skills, thank you! 73 de YO6SSW

Hi Sebastian, I've just noticed that your back to making videos and I have just watched your white board tutorials on the Wilkinson splitters again. I found that watching them again 6-9 months later that things very quickly fell into place, enough that I picked up on some important points that I had missed first time around. (Probably concentrating on the maths too much rather than the concepts) Your comments on the wave travel time to achieve the 180 degree phase shift really nailed for me one more aspect of transmission lines which I'm very shaky on at best. Any time you feel that you wish to expand on the "aside" of using and intermediate frequency and a second 1/4 wave transmission line to increase the bandwidth, I for one will be very happy to watch and learn. Thanks very much for the lessons... Rubin

Thank you

Life saver

Sebastian, Good teaching! Question: I ran an ADS model for a 2way Wilkinson combiner with 0dBm 0deg on each leg and output was +3dBm. Can you explain why when I either open or short one of the combiner inputs my output power goes to -3dBm? Also, is there a similar equation for an N way combiner as there is for an N-way splitter, that is, like dB=10log(1/N) ? thanks

thank you

thanks a lot

Sebastian, Very good explanation. I have one question for you. I was reading one of the text books and could not understand how the S-parameter matrix elements are obtained for these power dividers. So, could you please make a video or even give an explanation about the S-parameter matrix explanation for resistive and Wilkinson power divider ? Regards, Vinay Hegde

Hi, I'm trying to matching or coupling impedance between the transmission line and an antenna in an AM transmission, how I can use the Wilkinson Bridge to achieve this? Can you help me?

People with fabulous equipment make me feel like disappearing!

Hi, Excellent video. I learned something here! Although I was confused with the tear down portion of the video. Why were you surprised to find 2 inductors in the splitter? Your white board diagram did show 2 pi networks each with an inductor. Thanks

9:24 ''Once again, you can clearly see why I had an F in all arts related classes''... Lol

do you know something about power divider topology? 0-180° fot

how to design radial power combiner on IE3D software. from where i can get thoses files. need some help for my project.

Hi KF5OBS, I think the signals traveling total lamda/2 distance is actually 360 degree not 180 degree. So the signals from port2 to port3 are in in phase not out of phase. as wilkinson dividers are equal magnitude and equal phase on the output ports. As lamda/2 is equal to 360 degree as because in smith chart it accounts both transmitted and reflected wave which is total 360 degree. Please shed some light on it. Thanks.

Is there a way to use the traces to minimize parasitics of the resistor? literally assuming 0.5pF parallel capacitance and it reduces my isolation from 20dB to 11dB. I'm operating in the S band (2-4GHz), and my resistor is resonating at 2.5GHz. Based off the theory... I could select a resistor value (assuming capacitance is the same) so that I get 2*Zo impedance at my desired frequency. of course this would result in a narrow band wilkinson, but my application is also narrow band

what happens is one of the input port is left unconnected or unterminated? How much signal will reflect back?

11:50 I would never think that those two capacitors are parallel

I wish someone would explain this with resistors every antenna uses a 50ohm load so when you try to throw all the mumbo jumbo in it just doesn't make any sense or just say what is needed to make one

The math is still a complete mystery some examples would be nice 108mhz is the goal... I would like to upgrade all of my transmitters to Wilkinson combiners but I cannot figure out the math and I'm currently using resistive combiners...

Hi! Thanks for the Wilkinson article. I have a couple of questions. First, suppose I need much narrower bandwidth...say...the FM Broadcast Band. 88-108 MHz. I need really good port isolation above 150 MHz (40 dB). Can I achieve that with an 8 port design? How do I calculate the value for C and L? Thanks!
