Radio frequency distribution network standby power system with overvoltage protection

摘要

An improved overvoltage protection circuit for cascaded radio frequency signal distributing amplifiers interrupts a power transmission path in an open circuit mode responsive to an overrange input power potential, and is automatically reset to its quiescent operative condition when the overvoltage condition abates. AC energy is coupled by the instant arrangement at a reduced level while the fault condition persists, such that the driven load is continuously energized.
