It's been an eye-grabbing quote because no one is quite sure what it means. Was it a misstatement? Did she reach and grab for the wrong words? Or is Katy Perry making an allusion to Tesla's work with electricity?

Put very simply, "high frequency" typically refers to light, which is a high frequency manifestation of energy. Our most practical application of it is in the Tesla coil, that little piece of filament in a lightbulb that contains the energy and enables the neon and flourescent illumination commonly used today. Nikola Tesla parlayed this discovery into the wireless transmission of power, known now as radio waves. Set at a certain frequency (location on the dial), the coils magnify the signal.

It would appear that what Perry is implying is that she likes men who operate on a high frequency and/or amplify the energy the world throws at them. In short, larger than life is her type.
