PULSE SURGE PROTECTIVE GEAR Russian patent published in 2005 - IPC

FIELD: radio communications; protection of antenna-feeder assemblies.

SUBSTANCE: proposed device designed for protecting antenna-feeder assemblies against pulse surges set up due to lightning discharges that incorporates provision for electrical connections between input and output required to transfer supply voltage of antenna amplifier, for neutralizing adverse impact of high capacitances of voltage limiters on high-frequency channel characteristics, and for keeping induced voltage pulses in circuit being protected at minimal level has high-frequency line and series-connected isolating filter and arrester whose second lead is connected to ground; newly introduced in device are low-frequency line and second isolating filter; low-voltage line has low-pass filter incorporating low-voltage limiter; input of low-frequency line is connected to junction point of first isolating filter and arrester and its output, to input of high-voltage line through second isolating filter; T-shaped high-pass filter is inserted in high-frequency line between junction points of isolating filters.

EFFECT: enlarged functional capabilities.
