But, it is good to see them being available, so there still exists a market for them.

Good there is a place you can get them ....
The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.
