circuit design software

From time to time, we will be adding application notes related to the use of the WaveMaker software, in the design of microwave and optoelectronic circuits.

Harmonic generation using a step recovery diode and a filter circuit.

In this example, we use the  WAVEFORM software to predict the waveform from a harmonic generator circuit, consisting of a silicon step recovery diode (SRD), followed by an edge coupled microstrip filter. The simplified circuit topology is as shown in the next screen image.
