Nice video, Sebastian. Thanks for the mention - here's the link to the Toroid winding video:
How to wind a toroid inductor | A quick tutorial
Next, show us how to make a more broadbanded Wilkinson splitter.
The next video on the Wilkinson will probably be on the stripline Wilkinson in the GHz range. There we can do a little game with an intermediate input frequency and another 1/4 wave transformer to get teh bandwidth up. So stay tuned!
I dont mean to be so off topic but does someone know of a method to log back into an instagram account..?
I was dumb forgot the account password. I would love any tricks you can offer me.
@Coleman Hugh Instablaster ;)
@Karsyn Anders Thanks so much for your reply. I found the site through google and Im waiting for the hacking stuff atm.
I see it takes a while so I will reply here later when my account password hopefully is recovered.
@Karsyn Anders it did the trick and I now got access to my account again. Im so happy!
Thanks so much you really help me out :D
truly appreciate this. helped me understand more whats going on! thanks for sharing
Nice tutorial Sebastian, the first video I see from you. I would have liked to see a bit more on the importance of the resistor in the Wilkinson splitter / combiner. As a combiner, it becomes a critical component: the power dissipation capability of the resistor limits the maximum power of the device.
I'll go and watch now a few more of your videos.

Antonio Savila Thanks!
Hello - thank You for this video. Quick little note: winding on the left core is placed much closer to the PCB, so the parasitic capacitance on that part of the wilkinson splitter/combiner would be bigger then on the other side. I wonder if it would affect it's performance in 28 MHz range.
thank you
Hi Sebastian, Nice video. I have question on high isolation at 1Mhz to 100 Mhz, how to calculate the values
Hi Sebastian ! Thank you for the great video ! just a question ... why the XL need to be 1.41 x 50 ohm ?? ( or say: sqr(2) x 50ohm ) ?? May you explain me please ? Maybe I forgot the principles of electronics ... regards de HB9RXC Pietro
meteo091 hi, look at how microstrip Wilkinsons are designed. Basically the inductor shall transform the 100 ohm isolation resistor impedance to 50 ohm which is done by a quarter lambda transformer (in mstrip) with characteristic line impedance typically calculated by: sqrt(Z1*Z2)=sqrt((Z0)*(2*Z0))=sqrt(50*100)=70.7Ohm.
I am unable to find the name of channel for inductor you said . would you pls write here
Hello my friend
Can you help me calculate the coil and capacitor for 98Mhz?
The Coil if possible I pass in numbers of turns, measurement of the wire and diameter.
I tried to use his explanations, but since my mathematics is not very advanced, I could not calculate.
I await your valuable help
Thank you very much.
Wow
Normalized with respect to what? 6:54. and how would that take 3 hours to solve for L. :P
