Wow, once again you present something I've read about, and struggled with, and with one simple comment you bring it all into clarity. I don't think I've found anyone who explained that the cartesian plot is transformed into the circular form of the smith chart. I've just seen the Smith chart presented as-is. Now, as I watch the video, I imagine how the transformations look back on the cartesian view, and everything is making sense!

In case of the transistor, the maximum power transfer law doesn’t apply. Usually we deal with signal voltage here. Therefore we try to extract (or drop across the transistor input port) the highest possible voltage. We should consider it as a voltage divider circuit. So, the transistor’s input impedance should be as high as possible. We don’t match impedances there.

Thank you for the video, it is darn near exactly what I was looking for. If I were to suggest adding things, it would be to give the part number of the transistor you are using, and to show how you got the base impedance. I looked at the datasheet for the transistor I want to use and low and behold it has a piece of a smith chart showing the resistive and reactive components at a few different frequencies. There seems to be a trend so I think it is safe to interpolate a bit at least between the marked points. Thank you again for the video.

Seems that would roughly equate to a base DC bias current of about 720 uA and that seems pretty high compared to what Im used to designing.

Hi, I wanted to ask - you said you measured the input impedance of the transistor, do you have a video showing how you did that? I know RF transistors the manufacturer usually provides the "S parameters" which kind of give you this info already but I'd be interested in knowing how to do it. Would it depend on the emitter current somewhat though I would think? Seems like it would be a combination of emitter current/beta and the input capacitance in some way.
@AllElectronicsChannel Жыл бұрын
Yep, it depended on the physical construction and biasing condition. Some manufacturers give the S parameters in the datasheet and in some cases you need to measure it using a VNA.

I get delivering maximum power via a complex conjugate matching network but I don't understand your explanation that it produces maximum voltage across the base emiter junction of the transistor. Max voltage would occur when the input impednace of the transistor is many times the output impedance of the source, ie impedance bridging as in audio systems. With impedance matching you are only going to get 1/2 of the source voltage across the transistor. So why not jack up the tranistor impedance to be 10 times or more of the soure impednace to impose more voltage across the transistor? After all the signal inteligence is the voltage waveform, then if you needed more current follow up with an emitter follower to amplfy the current ?

Hi man! I'm glad you make this comment. This is a common misconception that a lot of people do, I also did many years ago. You are right. But, all breaks a part when you realize that a real transistor has a finite impedance, that cannot be changed. So, the best you can do is to match the source to what the transistor impedance is.

@@AllElectronicsChannel Thanks for the reply, I am not getting it. For reference I have an Electrical engineering degree from an ABET acredited university, although my concentration was in controls, I have also been a manager for the last 10 years so I am rusty, I am also an extra class Ham licensee, hence the intrest in this topic. Take the CE configuration, the input resistance is a function of the biasing network and emitter juction (re) which is a function of the transistor Beta and temperature or another word, so basically Rin = R1//R2//re, it can be a little different if there is an Emitter resistor RE and or a bypass cap. But in general the input reisistance is many 1000s of ohms. None of these componets are frequency dependent so what is driving down the transistor impedance ? What is the high frequency model of the tranistor ?

Thanks for the answer. But there is another thing that I can't understand. You say that your source has 50 ohm of impedance but what about if I build a receiver from a schematic and they say that a piece of wire 35 cm will be an antenna and then there is a 10 pF capacitor and then a regeneratove receiver circuit so in that case how could I know the impedance of the source signal? What if it changes, sometimes I can have my transmitter closer or further or weaker signal but I have no idea what impedance actually I have from my simple wire antenna point of view 🤔 Maybe my signal is weakend by mismatch and I don't even know it. There are a lot of things that are not answeared in books :( But when I grab a bokk for University there are a lot of equations which are not very usefull right away. I mean they are important but they don't explain the natural behaviours of things , only an ideal world.
