Patent ID: 8063716

Claim:
A signal splitter, comprising an input port; first, second, third, and fourth output ports; a first transformer having an input connected to the input port, and having first and second intermediate outputs, a first signal path from the input to the first intermediate output including a portion passing through a first ferrite tube, and a second signal path from the input to the second intermediate output including a portion passing through a second ferrite tube; a second transformer having an input coupled to the first intermediate output of the first transformer, and having first and second outputs; a third transformer having an input coupled to the second intermediate output of the first transformer, and having first and second outputs; a first Wilkinson device having first and second inputs coupled to the first and second outputs of the second transformer, and having first and second outputs coupled to the first and second output ports of the signal splitter; and a second Wilkinson device having first and second inputs coupled to the first and second outputs of the third transformer, and having first and second outputs coupled to the third and fourth output ports of the signal splitter.
