Beschreibung
Zusammenfassung:	A local oscillator device includes an oscillator module including a first inductive element and a capacitive element coupled in parallel with the inductive element. A frequency divider is coupled to the oscillator module for delivering a local oscillator signal. The local oscillator device includes an autotransformer including the first inductive element and two second inductive elements respectively coupled to the terminals of the first inductive element and to two output terminals of the autotransformer, the output terminals being further coupled to input terminals of the frequency divider.
