Abstract
Official abstract text for this publication.
A wideband RF choke circuit includes an input, first and second nodes, and a splitting means coupled between the input, first node, and second node. A first all-pass filter and a first line AC blocker are coupled between the input and the splitting means. Second and third all-pass filters, and second and third line AC blockers, are coupled between the splitting means and the first and second nodes, respectively. A first RF choke has a first end, coupled to the first all-pass filter, and a second end. A second RF choke has a first end, coupled to the second end of the first RF choke, and a second end coupled to the second all-pass filter. A third RF choke has a first end, coupled to the second end of the first RF choke, and a second end coupled to the third all-pass filter.
First claim
Opening claim text (preview).
What is claimed is: 1. A circuit comprising: an input, a first node, and a second node, and a splitting means coupled between the input, first node, and second node; a first all-pass filter and a first line AC blocker coupled between the input and the splitting means; a second all-pass filter and a second line AC blocker coupled between the splitting means and the first node; a third all-pass filter and a third line AC blocker coupled between the splitting means and the second node; a first RF choke having a first end, coupled to the first all-pass filter, and a second end; a second RF choke having a first end, coupled to the second end of the first RF choke, and a second end coupled to the second all-pass filter; and a third RF choke having a first end, coupled to the second end of the first RF choke, and a second end coupled to the third all-pass filter. 2. The circuit of claim 1 , wherein the splitting means is a directional coupler, the first node is an output, and the second node is a tap. 3. The circuit of claim 1 , wherein the splitting means is a splitter, the first node is a first output, and the second node is a second output. 4. The circuit of claim 1 , further comprising a fuse assembly that couples the first, second, and third choke circuits. 5. The circuit of claim 4 , wherein the fuse assembly includes: a first fuse having a first end, coupled to the second end of the first RF choke, and a second end; a second fuse having a first end, coupled to the second end of the first fuse, and a second end coupled to the first end of the second RF choke; and a third fuse having a first end, coupled to the second end of the first fuse, and a second end coupled to the first end of the third RF choke. 6. The circuit of claim 1 , wherein the circuit is configured to pass at least one of an RF signal and an AC signal omnidirectionally between at least two of the input, first node, and second node.
