ABSTRACT:
A voltage limiter for a coaxial cable line that carries an RF signal and an AC powering voltage signal is provided, including a signal input carrying a first AC voltage signal and an RF signal, a signal output arranged in series with the input and carrying the RF signal and a second AC voltage signal that is lower than the first AC voltage signal, and a voltage limiting mechanism arranged between the input and the output. The voltage limiting mechanism reduces the first AC voltage signal to the second AC voltage signal without substantially affecting the integrity of the RF signal.
