摘要： The invention relates to a novel high-speed actuated high-voltage RF switch for such purposes as the cold switching of short very high current RF pulses in applications such as solid-state Loran-C transmitters and the like, as for switching between coupling/output networks thereof. The switch comprises planar upper and lower unconnected pairs of longitudinally extending input and output bus strips electrically connectable by the transverse insertion of planar link strips slightly separated therefrom and the rapid compression thereof against the adjacent end portions of the unconnected input and output bus strips, enabling rapid switching absent wear of the contact surfaces, but with the provision of adequate spacing for high voltage operation and adequate contact pressure to eliminate current arcing.
