1.22GHz Line Extenders

Lindsay’s LBLE120A high output 1.2 GHz bi-directional broadband line extender is perfect for low cost per mile HFC deployments. The LBLE120A device is an outdoor-hardened distribution amplifier employing a single output, and the latest GaAs hybrid technology to provide superior performance to 1.2 GHz. The amplifier’s unique design allows for seamless upgrade configurations from 42/45, 85/102 and 204/258 MHz by simply exchanging plug-in filter sets, thereby future-proofing upstream bandwidth requirements.

The LBLE120A line extender comes with a composite power, full-band detect AGC in the forward path that provides a stable output with changing environmental conditions. The LBLE120A device comes with a 40-90 VAC HFC input switched mode power supply in a 15 PSI pressure tested housing. The LBLE120A can also be used as an EPAK (electronics package) to fit in an existing legacy amplifier housing. The LBLE120A line extender has sockets for JXP-style plug-in attenuators and EQs. Input and midstage attenuators and EQs are used for forward bandwidth equalization and balancing. An input attenuator plus an output attenuator and EQ are used for reverse path equalization and balancing. Universal JXP-style pads (JXP attenuators) are applicable for both attenuator and equalizer functions. The forward input EQ is the only custom type EQ used in the line extender.
