Abstract : The patent describes a microstrip instantaneous frequency discriminator operable at frequencies above 18GHz. A first power divider divides the input signal into equal power outputs which are used as the inputs to second and third power dividers. One of the outputs from each of the second and third power dividers is used as the input to a 180 degree hybrid and the other output from each of the second and third power dividers is used as the inputs to a 90 degree hybrid. The outputs of the 90 degree hybrid and the 180 degree hybrid are subsequently processed to provide signals suitable for a visual polar display of the instantaneous frequency and power level of the input signal.
