High power band pass rf filter having a gas tube for surge suppression

A high power band pass RF filtering apparatus for the filtering of electronic signals, the apparatus comprising:

• a sealed housing defining a cavity therein and configured to prevent a leaking of fluid to outside of the housing, the cavity at least partially defined by a conductive surface of the housing;
• a circuit component located in the cavity and coupled with the housing;
• a conductive element located in the cavity of the housing;
• an insulating element located between the conductive surface of the housing and the conductive element in the cavity for generating a capacitance;
• an oil disposed in the cavity and contacting the circuit component for dissipating heat from the circuit component;
• a connector assembly having a center pin electrically connected to the circuit component, the connector assembly secured to the housing and configured to provide an electrical connection from outside the housing to the circuit component in the cavity of the housing;
• and
• a surge protection element integrated with the connector assembly, the surge protection element electrically connected between the center pin of the connector assembly and the housing.

A high power band pass RF filtering apparatus with surge protection for the attenuation of frequencies outside of a pass-band, the high power band pass RF filtering apparatus comprising:

• a housing defining a cavity therein, the housing adapted to prevent a leaking of fluid from within the cavity to outside of the housing;
• a first wall coupled with the housing and positioned within the cavity, the first wall disposed along a first axis;
• a second wall coupled with the housing and positioned within the cavity, the second wall disposed along the first axis;
• an insulating material positioned within the cavity and adjacent to the first wall or the second wall;
• a first circuit component positioned within the cavity and coupled to the insulating material;
• a second circuit component positioned within the cavity and coupled to the housing;
• an oil disposed within the cavity and substantially filling the cavity, the oil submerging the first circuit component or the second circuit component for dissipating heat;
• an input connector assembly secured to the housing and having an input center pin, a portion of the input center pin positioned within the cavity of the housing;
• an output connector assembly secured to the housing and having an output center pin, a portion of the output center pin positioned within the cavity of the housing;
• an input gas tube integrated with the input connector assembly for surge protection, the input gas tube electrically connected between the input center pin and the housing;
• and
• an output gas tube integrated with the output connector assembly for surge protection, the output gas tube electrically connected between the output center pin and the housing.
