Abstract: A module for radio frequency signal circuits includes an electrically conductive housing. Coax connectors are secured to the rear face of the housing. A circuit board is contained within the interior spaced between sidewalls of the housing. A ground side of the circuit board includes a layer of electrically conductive material which is electrically connected to the housing. Coax cables extend within the interior of the housing from the coax connectors and between the ground side of the circuit board and an opposing sidewall. An opposite side of the circuit board contains circuit components interconnected with one another through a plurality of circuit paths.

Abstract: An amplifier switch controller is provided for use in a headend cable transmission system having first and second amplifiers and amplifier input and output paths connected to one of the first and second amplifiers, which becomes the currently activated amplifier. The amplifier switch controller comprises an input sampler for sampling a combined signal on the input signal path and measuring an input signal level. The amplifier switch controller also comprises an output sampler for sampling the amplified combined signal on the output signal path and measuring an output signal level. A program means receives the input and output signal levels and determines whether the currently activated amplifier is not functioning properly. If it is not functioning properly, the program means generates a control signal to a switch. In response to the control signals, the switch disconnects the input and output signal paths from the currently activated amplifier and connects each of the input and output signal paths to the other one of the first and second amplifiers.

Abstract: An amplifier module for radio frequency signal circuits includes an electrically conductive housing. Two coax connectors are electrically linked to an amplifier circuit contained within the module. A separate transformer is external to the module. Both the module and the external transformer are mountable to a chassis frame. Other modules are usable in the system in addition to the amplifier module. The transformer can be wall mounted to the chassis frame, or the transformer can be internal to a module which also mounts to the chassis frame.

The amplifier switch controller comprises an input sampler for sampling a combined signal on the input signal path and measuring an input signal level. The amplifier switch controller also comprises an output sampler for sampling the amplified combined signal on the output signal path and measuring an output signal level. A program means receives the input and output signal levels and determines whether the currently activated amplifier is not functioning properly (eg by determining whether the gain lies within a predetermined range). If it is not functioning properly, the program means generates a control signal to a switch. In response to the control signals, the switch disconnects the input and output signal paths from the currently activated amplifier and connects each of the input and output signal paths to the other one of the first and second amplifiers.
