PLEEEEEEEEASE NOTE the 7:28 mistake. ZL = 0 in a short circuit not Z0 (idem ZL=Infty in an open) Wonderful series by the way ❤!

[@robertodignoti3285]

Good job with this wonderful video. I want only highlight a mistake about the reflection coefficient. When you have an open circuit, the ZL=inf makes your Zo negligible and your reflection coefficient isn't zero, is about 1. On the oder hand the coeff is 0 when the Zo and ZL match (at 50 ohm for example).

Great learning experience. Thank-you. I am an RF tech, not an engineer, and have taken on re-tuning Codan C-Band amplifiers after replacing O/P FETs or repairing traces. Trial and error tuning really. These videos really help in understanding the underlying theory. Again, Thanks for this.

Loving these series! Keep on posting :)

[@robertbox5399]

This chap is amazing.

[@00xero]

I really love this

[@Sebastian-be8ez]

Excellent! Thanks

[@JuniGaspe]

clear explanation! thanks!

[@ozandogan948]

Great videos. Thx

From the Input Power point of view, it's internal impedance is important to avoid or control reflections problems.

[@myname49771]

Thank you very much for new knowledges and clear explanations. Would you answer on some questions please, sorry for my bad English. How to connect, in which point\points radius stub with Ground? By what wire width or probably by vias? The same questions about connections 7 quarter wave lengths in band pass filter?

What do you call 1/1000 of Zo? A millipedance?

[@YungPnut2404]

Videos have been amazing and very insightful to the world of RF PCBs. What resources would you recommend for learning the math behind all these concepts?

[@AltiumAcademy]

Hello Phil, David Pozar's textbook Microwave Engineering is a great resource. You can find it in digital formats or in print if you look online. We'll also be posting more videos on RF PCB design, so stay tuned!

Hi, greetings. I want design Flex PCB Antenna for GSM Frequency. Please make a brief note about layer Stack and Stubs Calculation. Thanks .

[@pcbdesign4495]

Greeting, are you going to post a real RF PCB design project using Altium Designer software soon ?

[@MuhammadAhsan-rr4js]

What about Grounded Wave guide Co planer vs Micro strip? Which is GND-SIG-GND vs SIG ? you did not explain!

[@AAFX-OM]

Why were you not my professor in college?

[@sharma_harsh]

Increase speed to 1.25x.. You're most welcome :)
