    • 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.
    • 本发明涉及一种新颖的高速致动高压RF开关,用于诸如固态Loran-C发射器等应用中的短的非常高的电流RF脉冲的冷切换,用于在耦合/ 输出网络。 该开关包括平面的上部和下部未连接的纵向延伸的输入和输出总线条对,通过横向插入与其稍微分离的平面连接条和其与未连接的输入和输出总线条的相邻端部的快速压缩,使得能够 快速切换不存在接触表面的磨损,而是提供足够的间隔用于高压操作和足够的接触压力以消除电流电弧。
