ABSTRACT
Provides suggestions on how to connect two International Rectifier's PVI1050S in series to provide a 20-volts tuning drive for a varactor diode. Filtering of any radio frequency currents from getting back to the photovoltaic stack; Use of resistors, ferrite beads and feedthrough and bypass capacitors to limit any RF currents.
