Computer Simulations and Experimental Investigation of the Heterodyne Employing Printed Circuit Board With an Increased Resistance to Electrostatic Discharges

Abstract—We have  performed computer simulations and experimental studies of characteristics of a standard analog device—the heterodyne employing a printed circuit board (PCB)  made from a composite dielectric with a controlled dark conductivity. Simulation results show that an increased conductivity of the PCB smaller than 2 × 10^7 Ohm^1 · m^1 has almost no effect  on the operating characteristics of a heterodyne operating in the frequency range of 9–37 MHz, which are in a good agreement with the experimental data. Such PCBs are expected to exclude  electrostatic discharges in spacecraft electronic devices otherwise  occurring in them due to their internal charging by the ambient  space plasma.
