Sir, we are actually using rf waves which has high wavelength compared to uv waves ..then actually the antenna size is directly proportional to the wavelength ..why don't we use uv waves for communication so that the antenna size is small so we no need to design big antennas and not required space to place antenna..?

asli keren dosen ini cara nerangin nya

sangat membantu penjesan fundamental tentang PLL, mantap

I browsed these videos and I should say there's nothing specific other than just general RF information delivered with broke English. It may be useful for a mechanical engineer who wants to talk about RF stuff in a family gathering 😅

What if you’re under electronic torture (V2K/RNM/DEWs)

T is the noise temp of the antenna here?

isn't dBm a 1mW reference?

thank you!

Useless video. You can get alot more information about the design of LNA if you just Google it!

5:00 Hit my question right on the head. I appreciate this video so much

The video tells about stability and not about constant gain circles.🙃

Mosfet cross coupled oscillator good for regenerative receiver.

Thank you

Finally, someone answered the most fundamental question. Thanks alot

The best explanation that i could find. Dametun garm a lot 😁🙏

Very nice clarification thank u 🌹

از لهجت‌ فهمیدم ایرانی هستی.خسته نباشی تشکر.کاش حداقل برای ایرانی ام ارزش قائل میشدی زیرنویس فارسی میزاشتی

fabrication of short circuit stub on microstrip possible or not?

صفا بچا ایران . عالی

Thank you for answering an important question that is overlooked many other videos: why can't we just use the VCO or the reference oscillator itself without the feedback loop.

Nice

Hello, Your tutorials are very good. I too am designing a LNA with a HEMT transistor, which type of topology would you think would be the best fit for it? Thank you

Thoroughly explained! I watched 3 videos and asked chat GPT and didn't understand why we use PLL, when we have crystal clocks and power amplifiers.

So...basically Saw filter and notch filter do the same as band stop and band pass filter...only difference is build materials and size...but basically they do the same job? Damn..i've been googling my ass off to find the difference between saw and band pass filters..found scientific papers about the surface acoustic wave tech and its use in military and how it guides missles. None of the info i found just put it simple: "imagine a SAW filter like a bandpass filter..only think in semiconductors"..that would save saved me a lot of time. Same with SWR vs LOGMAG...much blah blah but in the end both tell the same info..just different ways..

Great Video, understood the concepts easily thanks to you.

Is this what is referred to as "Tuned Power Amplifiers"?

Great explanation! I finally understand PLL

Power efficiency formula is wrong

trash why not make useful content not click bait to sign up for your course

türk müsün la konusmandan cok öyle geldi

Awesome explanation 👏

not accurate information

It's no longer free in your website. it's paid courses.

Useless

Why do we have an Amplifier before the Loop Filter? Is it because without the amplifier, the average DC voltage produced by the Loop Filter will be lower than needed? Will VCO will receive lower DC control voltage than needed due to the nature of averaging?

What is the threshold frequency below which all frequencies are considered low in RF design and above which all frequencies are considered high in RF design?

Why don't we just use the reference oscillator to provide stable input signal? How is the reference oscillator not prone to temperature and noise effects?

Thanks a lot for this great video!

bullshit bro

Sir kindly if you have this transistor file for ads sent me i need CGH40006P

Interesting. So a phase detector doesn’t only detect that two signals are in phase, but also that they have the same frequency. • Equal frequency and equal phase angle: constant zero phase difference. • Equal frequency but different angle: non-zero but constant phase difference. • Different frequency: time-varying phase difference.

Sir. What happens when LO and RF frequencies are same?

Your voice is very unpleasant.

very useful

you fucking idiot, are you teaching something or selling a course , if you are selling then mention it already

i need code for s/p in matlab

Thank you so much for answering the question that has been bothering me for long .You just gained a subscriber !

🙏🌹🌹
