Abstract
Abstract The controlled switching array comprises four commutator components and four associated signal distributors. Each signal distributor has an input side to which an input signal is applied which, in turn, is fed to a respective input on the input sides of the commutator components. The commutator components are symmetrically arranged on both sides of a printed circuit board. There thus results a favorable decoupling of signal lines from each other as well as from the output side.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
242 words
A controlled switching array comprising: at least three commutator components, each possessing an input side and an output side; at least three signal distributors having respective input sides and being associated with respective ones of said at least three commutator components; each one of said at least three signal distributors being capable of being supplied with an input signal on its input side; each one of said at least three signal distributors applying its supplied input signal to an associated input on said input side of said associated one of said at least three commutator components; a printed circuit board having two different sides; at least two of said at least three commutator components being arranged at least approximately at the same location but on said two different sides of said printed circuit board; each one of said at least three commutator components switching through said input signal applied to its input side to its output side in a controlled manner; at least one of said at least three signal distributors comprises at least two separate signal splitters; one of said at least two separate signal splitters being located in proximity to said input side of one of said at least three commutator components; an other one of said at least two separate signal splitters being located in proximity to an other one of said at least three commutator components; and a conductor for interconnecting said at least two separate signal splitters.
Claim 2
Dependent Claim
242 words
A controlled switching array comprising: at least three commutator components, each possessing an input side and an output side; at least three signal distributors having respective input sides and being associated with respective ones of said at least three commutator components; each one of said at least three signal distributors being capable of being supplied with an input signal on its input side; each one of said at least three signal distributors applying its supplied input signal to an associated input on said input side of said associated one of said at least three commutator components; a printed circuit board having two different sides; at least two of said at least three commutator components being arranged at least approximately at the same location but on said two different sides of said printed circuit board; each one of said at least three commutator components switching through said input signal applied to its input side to its output side in a controlled manner; at least one of said at least three signal distributors comprises at least two separate signal splitters; one of said at least two separate signal splitters being located in proximity to said input side of one of said at least three commutator components; an other one of said at least two separate signal splitters being located in proximity to an other one of said at least three commutator components; and a conductor for interconnecting said at least two separate signal splitters.
