Abstract:
1. A circuit for switching a PIN diode, comprising: a PIN diode; an inductor; a direct current voltage source; a group of switches; said group of switches being settable to a first switch setting that causes the PIN diode to be fed with current from the direct current voltage source in a conducting direction of the PIN diode and that precludes said inductor from being fed with current; and said group of switches being settable to a second switch setting and a third switch setting, said second switch setting occurring between said first switch setting and said third switch setting, and said group of switches causing said inductor to be fed with current from said direct current voltage source in said second switch setting, said group of switches in said third switch setting causing the PIN diode and the inductor to be separated from the direct current voltage source and connected in a closed current loop, and causing the inductor to generate a discharge current upon transition to said further switch setting, said discharge current being directed to the PIN diode in a direction opposite to the current generated by the direct current voltage source.
