Hi,

Can you use an RF Bipolar Power TRANSISTORS in an astable multivibrator circuit?

These have a higher operating frequency.

Like found here?

Thanks

 

I think so, but I wouldn't spend $40 for a transistor unless I knew how high the operating frequency needs to be.

 

It is an old aphorism in RF design that the best way to design an oscillator is to start with an amplifier. It doesn't even have to be a high gain amplifier.

Some of you old farts should take some time to compile a list of all the aphorisms that have stood the test of time into a single thread!

That way us young ones can learn a thing or two!

I have several to contribute, but the list would require somebody to manage it so it doesn't finish up cluttered with discussion and duplicates.

You can, but they aren't particularly fast in such an application. For fast switching you need a transistor optimized for switching, which is doped to reduce the storage time, such as the 2N2369. RF transistors don't have this doping and thus have a longer storage time, even though they are fast for RF applications operating in the linear region, where storage time is not a factor.

 

I will check out the 2N2369. Just what I needed.

Thanks
