Abstract :
A new proposed CAD method for the design of broadband microwave planar square law diode detectors is presented. In this method, the proposed broadband (low-Q) short circuit passive networks are used to contribute in diode matching. This method produces diode detectors with low VSWR over the useful broad bandwidth without using diode biasing (self bias) and without using resistance in the diode matching network. Examples of broadband square law Schottky barrier diode detectors designed using this method with their analysis are presented. These detectors have suitable topologies for realization using microstrip line or any other planar technology
