Abstract
A power sensor that enables determination of the frequency of a microwave signal comprises a signal input that receives the microwave signal at a particular frequency, at least one sensor that produces a first and second output corresponding to the power of the microwave signal, and a means for coupling the signal input to the sensor so that the coupling means distinguishes the first output from the second output in order that the ratio of these outputs produces a unique value at the particular frequency.
