Title: interstage transformers
Post by: KB8OYR on August 20, 2013, 08:02:55 PM
The ARRL Handbook cites many examples of broadband transformers to transfer power from one stage to the succeeding one.  It is stressed that the primary winding must present 4 times the inductive reactance of the preceding stage.  But my question is:  must the secondary winding also present 4 times the inductive reactance of the base impedance of the following stage or the ACTUAL inductive reactance of the base impedance of the following stage?

By now I'm embarrassed that I've enquired and I'm sorry for your time collectively.  Like I learned back in Sunday School.   "You're welcome as long as you don't ask questions, young man."

Indeed, you are always welcome here, questions or not 8). 

What you have asked is beyond the scope of most of us here, hence no replies :-X.

First off, one needs to clarify at what frequency your transformer is operating at; AF or RF.

There are some very highly versed technical minds on another forum, www.amfone.net.

I'd take my question there and be ready for an onslaught of diatribe :o.
