Abstract
A coupler for coupling a selected amount of energy from a transmission line 100 includes a contact 104 for contacting an inner conductor 102 of transmission line 100 through an aperature through an outer conductor of transmission line 100. A wire 106 of a preselected configuration is coupled to contact 104 and is spaced from a ground plane 108 to create a selected parasitic capacitance, the configuration of wire 106 defining a center frequency of the coupler. Coupler also includes a connector 110 having an inner conductor 111 coupled to wire 106.
