Abstract
An oscillator circuit for generating signals with a predetermined oscillator frequency is provided. The oscillator circuit has at least one resonator and at least one load impedance connected to the resonator. The oscillator circuit may be fully automatically trimmed and economically produced and, moreover, is of an improved quality wherein the load impedance comprises at least one structure which may be machined by means of high-energy radiation to trim the resonant characteristics of the oscillator circuit.
