Please do more topics on LNAs and RF. I love these videos. You are very talented and it really helps me learn more practical uses of things I vaguely know. If you could cover k-factor / stability topics that would be great to see!
Nice job ! I was also pretty amazed to see the bandwith and flatness of this amplifier when looking at the through hole resistors. Maybe they even use the inductance of the resistors as a RF choke. Pretty crazy to think about that the smd capacitors might have been brand new technology when this circuit has been built. Thanks for taking such an in depth look at it, there is a lot to learn on even such a "simple" design. The japanese engineers really knew what they were doing and how to use cheap components.
Top, top, top! I believe that with a master's and a doctorate you can be a great university professor! You have an unusual didactics to explain the projects and it proves it in practice.
3:03 I share your love for simple, elegant, low-tech, low-cost designs which achieve great performance through care, attention to detail, and hand-tuning.
I've been trying for years now to build a simple receiver and still no success. I hope you can explain how to me how to design a front end. specifically how best to couple to the tank circuit. I mean, the tank is high impedance, at least 5k ohm (measured) common base is very low impedance, even common collector at RF has a low impedance. If i have the tank in the collector circuit then I'd have too much gain in the front end and the miller effect becomes an issue ... basically, do you have, or could you please make a video, describing good practice for a front end? antenna, tuned circuit etc... i know it's a lot to ask but i've been trying for so long with no success
@@AllElectronicsChannel bueno.. entonces voy a intentar: bias el transistor con 12mA, couple el antena al emitor, tank en el collector, y lower tap el tank para couple al proximo stage.... gracias!
Gregory, podrias hacer una guia de como diseñar lineas de transmision con strips? y filtros de banda con PCBs? desde ya muchas gracias!!! y adelante con tu canal!!! Un gran saludo desde Mendoza FF57nc

After 4 years of Electronics Engineering I finally understand this stuff and it's amazing
in the 80's satellite dishes used an LNA as a probe. very similar to the one in your..Great video very good content.

Thanks my friend!
You're welcome

I like your spirit.
Great video as usual!
I'm glad you think so!
hi grey, can you please make a video about mixer (about the basic)? thx
Great.. Keep going.. your way of explaining things is mazing..!
Thanks!!
como siempre, un capo Gregory!
gracias!!

Little tip: you can couple the transistor in a lower tap on the inductor, a lower tap will have lower impedance 😏

@@coffeecuppepsi Nice!! good luck!
@@AllElectronicsChannel Amigo!!!! Looks like it worked, now I'll try to add a second amplification stage ! Muchisimas gracias

Hi Leo! You will not believe.. I bought a bunch of vacuum tubes.. 😂😂😂 what are we going to create?
Very cool
