Abstract
An oscillator operable in the gigaHertz range includes a transistor having an emitter coupled to a tank circuit and an additional feedback path coupling the tank circuit back to the base of the transistor. The inductive elements of the tank circuit are in printed foil form as is a transmission line that provides the additional feedback path. This arrangement improves the phase noise characteristics of the oscillator while extending its operating frequency range.
