The phrase "a function of the frequency of" is correct and usable in written English.
It can be used in contexts where you are discussing how one variable depends on or is influenced by the frequency of another variable.
Example: "The intensity of the signal is a function of the frequency of the input wave."
Alternatives: "dependent on the frequency of" or "related to the frequency of".
Z is a function of the frequency of the source of applied electromotive force.
Analysis of the harmonic components of the current has been carried out as a function of the frequency of the voltage perturbation signal.
The mutual impedance technique is based on the measurements, as a function of the frequency, of the quasi-electrostatic coupling between an emitter and two receivers separated from the emitted source by at least twice the local plasma Debye length.
Results for the transmission and reflection properties of such circuits (nanometric networks) are discussed, as a function of the frequency of the excitations and the physical or geometrical properties of the circuits.
The damping is formulated through the hydraulic resistance of the fluid path as a function of the frequency of flow oscillation and mean flow velocity for the laminar and turbulent flows.
