1277444 Semi-conductor oscillators TELEFUNKEN PATENTVERWERTUNGS GmbH 7 July 1969 [19 July 1968] 34146/69 Heading H3T [Also in Division H1] An oscillatory pulse generator comprises a semi-conductor body H arranged to operate as an oscillator delivering microwave oscillations produced by the L.S.A. or Gunn effect, the body having a plurality of anodes A1-A8 surrounding a common cathode K, each anode being connected to the individual radiators of a multiradiator radar aerial array. The lengths of the paths between the cathode and the anodes or the doping of the material in these paths may be different so that oscillations at the anodes will have different phases suitable for connection to particular radiators. Phase shifters and amplitude controllers may be inserted in the path between anode and radiator. Intermediate electrodes may be present to control the frequencies of the oscillations and the device is mounted in a resonator which is tuned by capacity diodes. Triggering is effected by pulses from an independent source or fed back from the oscillator output. More complex structures may be provided by superposition of bodies.
