Abstract
A delay line frequency discriminator having application to microwave equipment and particularly used for stabilizing an oscillator, including a first coupler supplied by the oscillator and connected to a second coupler by means of two electromagnetic transmission lines, wherein one of the transmission lines introduces a delay time .tau. compared with the other line. The second coupler delivers a sum signal which is the stabilized output signal of the oscillator and a difference signal to a third coupler which is also fed with a sampled portion of the output signal of the oscillator and supplies the oscillator via a detector and an amplifier.
