is there any trade off between power and frequency?

No. The two are totally independent quantities.
The question you posed is really not well posed in the abstract; one can conceive of numerous situations where there is a "trade off between power and frequency" but only because of the specifics of the problem. For example:
a In human hearing as one ages, higher audio frequency hearing loss is common and one needs to have those higher frequency components amplified more in a hearing aid.
b) In radio frequency propagation in free space, the attenuation is proportional to the square of the carrier frequency -everything else being equal- and one has to use more power at the higher frequencies to "close the link". In practice however, this is not so because at higher RF frequencies one gets more "gain" from a given size parabolic reflector dish at the antenna.
But in your general abstract question, there is no trade off between power an frequency.
