A powerful method for designing broadband varactor‐tuned negative resistance oscillators is presented. The CAD procedure stems from a novel way of employing Hilbert transform techniques. The method is capable of realistically taking into account the decisive factors governing oscillator performance and directly processes measured large‐signal data of the active device without relying on an approximate circuit model for the device. Device—circuit interactions at higher harmonic frequencies are not considered in the context. A transferred‐electron oscillator design example is used to illustrate the method.
