The present invention relates to a divider network for dividing an HF signal into n output signals of the same power and phase at the same impedance as the input, where n is a positive integer greater than 1. Each of the n signals is fed to an output port. Each of the output ports has associated therewith a transformer. Each of the ports is connected to ground via at least one winding of the transformer. Each of the ports is connected to a common point by a winding of the transformer so that each transformer is connected in parallel with respect to the common point. The HF signal is fed to the divider via an input port. The input port is connected to the common point so that the path length between the input port and each of the output ports is substantially equal.
A signal dividing network is provided as an RF splitter for use in supplying N load devices of varying impedances with RF signals such that each of the N signals is of essentially the same magnitude and phase. The splitter includes a plurality of step-down auto transformers, each having a primary and a secondary defining a series circuit between a common RF source and ground. An output terminal is defined as the midpoint of the primary and secondary windings on each transformer and the output terminals are connected together in common whereby all of the primary windings are connected in parallel and all of the secondary windings are in parallel. Each output terminal has several outputs connected thereto such that the splitter has a total of N outputs for driving N load devices.
A tap for coupling electromagnetic energy between first and second coaxial cables. The tap comprises a pair of coupled transmission lines, means for connecting said transmission lines to said first cable, and means for connecting said transmission lines to said second cable.
Two unequal impedance input port RF power combiner is used alone or as a component of a three equal input impedance input port RF power combiner with isolation between all ports. The combiner has a band pass of at least two octaves and the capacity to handle at least 5 kw. The combiner may be used in a transmission system and methods of isolation of the input ports by the resistive shunting of selected transformer windings are disclosed.
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.
