ABSTRACT:
A radio frequency attenuating connector includes a secondary coil connected to a load, an electromagnetic shield enclosing the secondary coil and the load, a primary coil, a coupler for detachably coupling the primary coil and the secondary coil, an integrated circuit including a square wave oscillator producing complementary output signals, and first and second switching devices. The first switching device is responsive to one of the complementary output signals for causing a current to flow in one direction through at least a portion of the primary coil during a first half cycle of oscillation, and the second switching device is responsive to another of the complementary output signals for causing a current to flow in an opposite direction through at least a portion of the primary coil. The integrated circuit has an enable feature and includes additional protection circuitry for enhancing the safety of the radio frequency attenuating connector.
