Patent ID: 8742869

Claim:
An electrical circuit comprising a high power, low passive inter-modulation capacitor, a second capacitor, and an inductor disposed within a metal enclosure; the high power, low passive inter-modulation capacitor comprising first and second metal layers affixed to a pair of substrates, the first and the second metal layers broadside capacitively coupled through an air dielectric gap, a first substrate of the pair of substrates having two planar surfaces parallel to the air dielectric gap, one of the two planar surfaces of the first substrate having the first metal layer affixed thereto, which forms a first terminal of the high power, low passive inter-modulation capacitor, and a second substrate of the pair of substrates having two planar surfaces parallel to the air dielectric gap, one of the two planar surfaces of the second substrate having the second metal layer affixed thereto, which forms a second terminal of the high power, low passive inter-modulation capacitor; the second capacitor having a third terminal and a fourth terminal, the third terminal formed by a third metal layer affixed to either of the two planar surfaces of the first substrate, and the fourth terminal formed by the metal enclosure; and the inductor formed by a connecting metal layer affixed to either of the planar surfaces of the first substrate, the connecting metal layer connecting the first metal layer and the third metal layer.
