Abstract: A hollow cylinder of electromagnetic energy-absorbing material forms a portion of the outer conductor of a coaxial transmission line, the portion encompassing a mercury-wetted, magnetic field operated, reed switch that joins center conductor portions of input and output coaxial lines. When actuated by an externally generated magnetic field, the reed switch is operated to cause a relatively undistorted, sharp voltage step signal to flow along the output coaxial line.

Abstract: A transistor suitable for operation in the avalanche mode is connected in a switching circuit through coaxial lines. The outer conductors of the coaxial lines are electrically bonded to a base member and the center conductors of the coaxial lines are bored out to receive the ends of the transistor leads directly.
