ABSTRACT:
Apparatus and systems, as well as methods for using them, may include launching a pulse into an input port of a quarter-wave directional coupler having an thru port and an isolated port, and receiving a leading edge of the pulse as a voltage spike at an output port of the coupler. A switch may be activated to couple a pulse source to the input port. The impedance of the coupler may be selected to match the resistance of the switch added to the impedance of a charge line included in the pulse source.
