An apparatus and method for coupling energy from a transmission line is provided. The apparatus includes a contact designed to &ldquo;tap&rdquo; into an inner conductor of the transmission line through an aperture in an outer conductor of the transmission line. A portion of the contact may be coiled (e.g., a spring) and the coil's characteristics may be varied to control the insertion loss and coupling loss of the apparatus. For example, the wire size, coil diameter, number of turns, and pitch design of the coil may be controlled. The apparatus may also include a secondary transmission line connected to the coil and the secondary transmission line may allow additional control over the coupled energy.

Device for coupling radio frequency energy from various transmission lines using variable impedance transmission lines

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