A transmission line structure, a transmission line thermal manager and/or process thereof. A transmission line thermal manager may include a thermal member. A thermal member may be configured to form a thermal path, for example away from one or more inner conductors of a transmission line. A part of a thermal member may be formed of an electrically insulative and thermally conductive material. One or more inner conductors may be spaced apart from one or more outer conductors in a transmission line. A transmission line and/or a transmission line thermal manager may be configured to maximize a signal through a system, for example by modifying the geometry of one or more transmission line conductors and/or of a thermal manager.
