Time-Domain Modelling of Solid State RF Receiver Protection Systems

We investigate the effects of switching the state of a PIN diode from insulating to conducting as a component within a Solid-State Receiver Protection (SSRP) system. The investigation follows a component adding process, ultimately arriving at a full configuration of a metallic post insulated from the waveguide by two dielectric blocks in the Off-state, which is then connected at one end in the On-state. The effects of the diameter of the post are also studied. The S-parameters of the system are calculated from the voltage and current transmission line observations sampled directly with a single time-domain numerical method based upon an unstructured mesh.
