Abstract

1. A frequency divider for very short wavelength electro-magnetic waves, with an oscillator whose harmonics are synchronised and which has an amplifying semiconductor element (Tr), characterised in that there is inserted into the feedback path from the output to the input of the amplifier element (Tr) a line portion (K) connected in series with a coupling capacitor (CK ) and which is of such length (1), that in the case of the divided frequency the phase rotation of the fed-back oscillation is supplemented to a value of 360 degrees by the amplifier element (Tr), and there is inserted into the output circuit of the amplifier element (Tr) a series resonance circuit (L1, C1) whose resonant frequency lies approximately in the centre of the band of the divided frequency.
