ABSTRACT:
High frequency signals and power carried in a main cable delivering the same to a device are insured continuance flow within the main cable through use of a shorting bypass bar assembly in the device that is activated to electrically connect input and output ports of the device whenever the cover of the device is removed for servicing, for insuring continuity of the signal and power flow through the main cable. The shorting bypass bar itself is electrically connected to ground whenever the cover of the device is installed and the shorting bypass bar is disabled. Also, printed circuit board connectors for coupling to the input and output ports of the device to conduct signals from the input port into a PCB board for processing, and for delivering signals and power back into the main cable from another PCB board connector, include RF shielding, and the minimization of the size of the electrically interconnecting components both on the PCB connectors, and on the shorting bypass bar for maintaining a 75 ohm impedance at all times for electrical signals having frequencies ranging from less than to at least 3 GHz.
