Power Supply Requirements And Voltage Calculations For Cable Powered CATV Systems (1979)

By James K. Waldo

I am reminded repeatedly of how very basic and straightforwared calculating voltage drops and subsequent amplifier voltage inputs is. I have learned, that unless calculations are made on a consistent basis, though they are basic, aren't quite as straightforward to the average technician as one may think. If the Chief Engineer, Design Engineer or whoever is not familiar with how to calculate voltage drops and subsequent voltage inputs to the various amplifiers, the end result can be very costly. The following is an attempt to show and or explain how these calculations are made, so that the end result will be a well-designed power distribution system as well as a well designed RF system.
