Tuned reactance cavity electrical termination

An electrical termination system includes an electrical contact electrically connected to an RF resistor (224). A housing (102) at least partially encloses the RF resistor (224). In one alternative, the housing (102) includes an electrically conductive surface located at a first distance relative to the RF resistor (224) to provide a reactance at the RF resistor (224) to reduce reflected energy at the electrical contact for a wide band RF signal present at the electrical contact. In a second alternative, a surface of a dielectric substrate (602) is located substantially adjacent to the RF resistor (224) to provide a reactance at the RF resistor (224) to reduce reflected energy at the electrical contact.
