Abstract: An oscillator arrangement is disclosed which is controllable in its frequency and which comprises a control input for frequency variation and a transformer output, whose frequency-determining oscillating circuit possesses, as a controllable reactive element, two varactor diodes which are connected in opposing fashion and whose capacitance largely represents the oscillating circuit capacitance. Two feedback oscillator circuits are combined to form a push-pull circuit in that the output terminals of the oscillator circuits are connected in respect of d.c. to a reference potential by way of a central tap of the primary winding of a common output transformer. In addition, the two varactor diodes are oppositely poled and interconnected in respect of d.c.
