Single Hybrid Junction Frequency Discriminator.
Abstract
A single hybrid junction discriminator is described for operation over a wide operating frequency range. The single hybrid discriminator uses a transmission line, phase shifters and fixed short circuits in providing a resonant cavity in the discriminator element to form a device that will measure near carrier frequency modulated noise on a carrier frequency. Only a minimum exchange of circuit components is required for changed carrier frequencies. With the phase shifter located in the signal channel, operation is a direct and easy process for quadrature detection. Component arrangement is critical to the operation of the single hybrid discriminator. The single hybrid discriminator is more sensitive than either the two hybrid or one hybrid and a directional coupler type discriminator because better useage is made of the available signal power.
