Abstract
Abstract 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.

Claim 1
Independent Claim
178 words
A divider network for dividing an HF signal into n output signals of the same power and phase, where n is a positive integer greater than 1, wherein each of said n signals is fed to an output port, each said output port having associated therewith a transformer, each said output port being connected to ground via at least one winding of said transformer, each output port being connected to a common point by a winding of said transformer so that each transformer is connected in parallel with respect to said common point; said HF signal being fed to said divider via an input port, said input port being connected to said common point and said common point being connected to the output port transformer by means providing a path length between said input port and each of said output ports which is substantially equal, said common point being connected to said input port via one winding of another transformer, said common point also being connected to ground by at least one other winding of said another transformer.
Claim 2
Dependent Claim
