ABSTRACT:
An oscillator circuit includes a resonant circuit having a capacitor and an inductor. The inductor has two main terminals, a center tap and two further taps disposed symmetrically relative to the center tap. The inductor is constructed as a U-shaped stripline in which the center tap is disposed at a turning point of the U-shaped stripline, the main terminals are disposed at ends of legs of the U-shaped stripline and the further taps are each located at the same distance from an end of a respective leg.
