Re: RF Transformer
You could ask a similar question about nearly any parameter of electronical devices, that is not exactly specified by the
manufacturer. What answers do you expect?
It's practically impossible to specify any parameter exactly. If they do, they possibly have to measure it in production.
You'll notice however datasheet comments, that many parameters are given "by design" rather than actually measured. If
you are a practical man, you'll also know, that datasheet specification are not certainly correct. So again, what are you
actually asking for?
If the said imbalance parameter matters in your application, you should do at least this:
- determine the real variation for a number of samples
- try to understand the physical reasons causing this variation
- try to get inofficial statements from the manufacturer regarding expected variation
- as suggested by flatulent, plan means to correct larger variations (at least up to the specified limits), that may occur later in
production, hoping they won't be ever needed
