An attenuator incorporates a matched circuit which directs a portion of the input power to a power detector (25). In response to the power level reaching a threshold value an actutor breaks the circuit through the attenuator to provide reverse power protection.

In many microwave applications poor repeatability of results is often caused by differences in the quality of the coaxial connections. This invention overcomes the problem by ensuring more uniform connection by providing two mechanical connecting means radially separated from each other and coaxial with a central conducting means being connected, thus ensuring precise alignment of the two conductors.
