The phrase "at frequency of" is correct and usable in written English.
It can be used when discussing the specific frequency at which something occurs or is measured, often in scientific or technical contexts.
Example: "The signal was transmitted at a frequency of 2.4 GHz."
Alternatives: "at a rate of" or "at a frequency of occurrence".
