This multi part video focuses on the critical design aspects of an RF Push-Pull amplifier. The example shown uses an IRF510 MOSFET transistor to explain impedance matching, biasing, amplifier classification, circuit stability, feedback, tuning, power output, harmonic distortion, and other important design characteristics. From this video, the viewer will gain an in-depth understanding of how to design, build, and test an RF power amplifier.

Thanks for sharing all step by step! Really appreciate your detailed explanation across the PA design

@Mark_KE8YCV 5 месяцев назад

Your presentation and explanations are as clean as your amps. Veteran machine system designer here but total RF rookie so I'm learning a ton. Thank you!

Thank you for an excellent set of videos on RF amplifier design and testing.

Excellent information, thorough and well presented. I just watched the entire amplifier series, and now think I can build a similar amp from scratch. That makes me smile, because understanding and working with RF are what ham radio is all about. Thank you.

Thanks a whole bunch for making all these videos and the work that you put into them; they are just great! Also, amazing what you can do with IRF510s, a real little 'trooper' of a device! I am planning to get into all this since I'm now retire so been collecting parts and equipment; just now need to fill-up on the theory. Again, really appreciate it and 73...

Excellent series! Subscribed for more of the same and similar.

@ashokjoshi7933 Год назад

Very nicely explained . Excellent guide for making a good PA, which am planning to make. Thanks sir.

Hi, I watched the whole series, thanks a lot for the good videos and the great summary of formulars. Is there a chance to get your slides as pdf? Greetings from Berlin, Germany

Great videos. I have just gone through a lot of your videos and found them interesting. I am not a communication guy but really interested in finding a working simple circuit (made at home) for RF control transmittier and receiver for one bit or 4 bits over a few km and how to design an amplifier and choose an antenna to make it tens of km. I hope you can share some designs or resources and better if you could go through some videos designing and testing them

@destro5738 7 месяцев назад

Excellent video series! I would like to ask what type of 4W preamplifier it is? Thanks!

@yoanndelacalle3304 8 месяцев назад

Hi, thank you very much for your videos. I built your amplifier, and now I need to set it up. I have juste 15W on the output but I do not use M43 material, so I will change my trasformer. Just a quick question, because I am so happy to understand a full video in English: where are you from? Thanl you again , 73

First row in the table - FB resistor should be rather infinity than zero ohms for 0% of feedback ;)

@RGB06084 Год назад

Well done sir! I enjoyed the series! Are those circuit boards available?

@rfmanchannel6915 Год назад

If I get enough requests, I will order some boards and post them on my web site for sale. rflinear-amplifiers.com

@ioannismanousakas3040 Год назад

Hi, thanks for the nice videos! Could you provide the sizes for the cores of the chokes and transformers? Thanks!

@rfmanchannel6915 Год назад

These cores at 1" x 1" material 43 binocular ferrites. They are available from Arrow.com. Regards

Do you have any scope waveforms of the drain voltages ?

@wookie54444 Год назад

What a great series thank you can you tell me where i can get a copy of the notes you show in the videos or can you sell me a copy a i would like to learn more and do some experimenting.

@10:53 The feedback resistors actually made the 3rd harmonic worse, not better, because the fundamental went down more than the 3rd harmonic did! If you had put markers on you would have seen this.
