[Amps] the dumb question of the month?

[Dan Sawyer <dansawyer@earthlink.net>]

All,

I am trying to figure out ferrite output transformers. This question is:

"What does the frequency response of a ferrite transformer look like?"

The output power transistors have been removed from an RF amp. When a 50 
Ohm swept signal is feed backward into the amp output - the signal at 
the collector exhibits a dip with frequency. Is this dip  the  resonant 
point of the output transformer??

Thanks,
Dan
