Abstract: 2 102 104 116 124 120 122 118 112 108 110 106 FIG. 3 (57) : A combined isolator-diplexer device for supplying radiofrequency (RF) energy and microwave energy obtained from separate sources to a probe via a common signal pathway. The invention combines into a single unit all the necessary components to isolate a microwave channel from an RF channel whilst providing a high withstanding voltage (e.g. greater than 10 kV). The device comprises a waveguide isolator for isolating the microwave channel having a pair of DC isolation barriers arranged therein to provide a pair of series- connected capacitive structures between a ground conductor at an output of the combining circuit and a conductive input section of the waveguide isolator.
