Abstract

Switching, regulation, amplification and/or attenuation system which may be adapted to switches with several R.F. inlets, R.F. amplifiers and R.F. convertor selectors, suitable to be employed for the realization of radio and television recep­ tion systems or the like, whether fixed or mobile which com­ prises a power supply and control box (1) containing a radio-­ frequency filter or injector; a block (20) consisting of a standard unit for the selection, conversion and processing of the R.F. signals and/or an R.F. switch with several R.F. inlets and identification, switching and regulation circuits capable of identifying both the polarity and the particular value of the voltages received, coming from control and power supply box (1) and consequently to control the coupled control cir­ cuits of the R.F. switch and/or R.F. conversion and processing unit; one or more blocks or modules (25) or (25′), whether inserted or not in the same block (20), consisting of amplifica­ tion, attenuation or tuning circuits of the R.F. signals, com­ bined with power supply and regulation circuits able to power, at constant voltage, the above mentioned R.F. amplif­ ication, attenuation or tuning circuits, and to carry out the regulation by utilizing the same voltages at different pol­ arities, transmitted, in turn, by control box (1).
