Building a Wilkinson Splitter/Combiner [RF Circuit Design]

[@w2aew]

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.

@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.

[@colemanhugh6317]

@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

Great!

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. Regards from UK Antonio

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.

Hi Sebastian, Nice video. I have question on high isolation at 1Mhz to 100 Mhz, how to calculate the values

[@vijaybaleja6220]

I am unable to find the name of channel for inductor you said . would you pls write here

[@meteo091]

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

[@stefanhummelink3662]

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.

Normalized with respect to what? 6:54. and how would that take 3 hours to solve for L. :P

[@marcelloih]

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.
