RF Design-9: RF LNA Design - Concept to Implementation

Loved it! Thank you!

Can I import BFP740FESD FET transistor in ADS,I am unable to that.

Hi Anurag, You are my inspiration and my hero as far concern about RF simulations and its explanation

No longer l will try to learn about RF engineering. I love RF and antenna. But there is 1.5 BILLION 😮 of Indian who are mostly study engineering 😢. India make biggest inflation of engineer in the world. I can painting very well. I will attend a grafic design department. Become something Indian can’t do. Every Europe become Indian recruiters to software developer. Master program is %80 of Indian. This is end of 😢 road for me.

I have Designed RF PA using ADS ...refreshed my memories regarding ADS . Thanks for Sharing

Hi Anurag, thanks for the great presentation. When you mention that at high frequency there are no inductors available, is it because of self resonance due to parasitic capacitance of inductors?

Thank you? Could you help please? You are said, that frequency is 2,4Ghz and lambda/4 line is 19.8mm? How is it possible if lamda for 2.4GHz is 0,125m? 0,125m/4=0,031m

thankiuuuuu, fromm VietNam with love, that's an amazing video

I cant download the workspace. Can yu provide the link for downloading the workspace?

Sir.. can You provide the link for AFT21170 PDK non linear model download ?

how to make lna for 2.4ghz step by step

It is really useful

Can we get this design of yours?

Sir, after I unzip the design kit and click ok when the dialog box appears if I want to add, there are no libraries or schematic added to my workspace. What should I do?

Great Explanation! I wanted to design the LAN by "hand" with some python scripts and smith chart but did not had the whole overview after reading books and application notes. With your explanation its much clearer now.

Sir,
I saw many videos all are well explained. thank you so much.

hi,
how can i get and import TSMC 180nm PDK in ADS

Hi..
thanks for this helpful video,... i have a question
if we are going to design a cmos amplifier with many transistors and resistors, etc...., how can I simulate it (with a model)

Thank you, Sir for this wonderful lecture and covering the complete design strategy of LNA. Unique to this content is the stability network design. Because in most texts on LNA design, impedance matching of the active device under unconditionally stable condition is shown and not the strategies on the stability network.
Therefore, you are right when you mentioned that this material is 'not available elsewhere' in the Introduction slide😀. Do let me know if this perspective is correct.

Sincerely,
naive MMIC designer

We're waiting for MMIC LNA design.

Lots of MMIC videos, any Front End non-MMIC videos?

Sir, Thank you for giving a wonderful lecture video. This helps very RF engineers and academicians to know LNA in detail. I am designing a Microstrip Isolator, can u help me with how to include ferrite magnetic materials in the design? Give some book references for the design.

thank you for video. sir i have one doubt that if i have a datasheet of gan HEMT and want to use in ads then you told we can use it through s2p. but i have doubt how to assign gate source and drain terminal to that box(snp) or how i understand which terminal is gate source drain (like there will 1 2 and ref terminal.).

Thanks Sir.

Very good initiative, really appreciate your efforts in sharing your knowledge

Sir, ATF-21170 is a NMOS or a PMOS device?

Nice video, can i get calculation of this lna design

Thanks a lot for this tutorial, I could not figure out how the 90deg and 50 Ohms became 1.1 width and 19.8 length. I have used LinkCalc and the result was 18.6 length and 1.07 width, ??

Can anyone suggest me a good book for LNA design?

hi sir....tutorials are very useful....i have doubt sir,....How to convert lumped element to microstrip.. inductor converted to microstrip and same as capacitor....

Sir, Your tutorials are very encouraging for new learners...!!
One small request, for upcoming videos, if possible please provide links in the description for previous video tutorials wherever you are mentioning it in the current tutorial..

Thank you sir

Sir can I please get to know what is the name of the template you use for s parameter simulation

Thank you

Thank you very much sir for sharing all these videos. Sir it would be very kind of you if you could make some videos on PIN Diode models.

Thank you sir! It is so much info and very clear. How did you pin pick class A operation point on the DCIV curve please?

I ask another question, i have to go back and forth with my design. i achived stability with my particular bias network and transistor but now my MAG is around -1.7 while it was around 20dB with the previous bias network (but unstable).. do you have a tutorial to design the network to optimize for gain with an stable system? thanks

Thank you so much! I need to listen to this again because there were many things pointed and it is totally worth the time spent. Much appreciated!

@Anurag Bhargava Dear Sir, I have gone through LNA tutorial 9-10 videos but it could not solve the problem. First, you used series resistance at the input and output sides separately. Then, you deactivated input resistance, and connected RC network towards the ground. The values were picked previously and there was no information for derivation. Best regards.

Thank you sir for such detailed videos on RF Circuit designing. I designed the LNA circuit mentioned in video but got "Warning detected by hpeesofsim during netlist flattening.
Resistor `A1.RSSP' is shorted." this as warning because of which results are not coming. KIndly help.

Hi Sir, thank you so much for these tutorial videos.
If I may, I have a question. Would you not need a T-junction component in the schematic when adding the radial stub at the time-mark 50:20? Thanks beforehand!

Hello, this very a good tutorial. I'm designing a low noise amplifier too and it's very difficult because I usually don't use ADS software. Do you also provide services for people who want to design and simulate LNA with ADS software? Thankyou..

Do it with AWR too. If possible

Hi Anurag, I hope you have time to write a book design Low Noise Amplifier, and Power Amplifier from A to Z . If you do that many people are happy for your helps. I will buy two books .Thank you for your tutorial.

Sir, how can I download these transistor kits for my ads?

Thank you very much for your tutorial LNA design. That helps me learn a lot.
