LHA38RM 1.2 GHz MDU Distribution Amplifiers

This Lindsay exclusive MDU amplifier delivers reliable performance supporting DOCSIS® 3.1 frequencies to 1.2 GHz. The unique design allows for seamless upgrade configurations from 42/54, 85/102 and 204/258 by simply exchanging plug-in filter sets, thereby future-proofing upstream bandwidth requirements.

The LHA38RM-x-xx amplifier is designed for advanced HFC network installations in apartment buildings, hotels, schools, hospitals and similar facilities having high RF amplification requirements. Designed with high gain, this two-way, upgradeable amplifier uses the latest 1.2 GHz GaAs-FET push-pull technology to provide superior distortion performance and low noise. This amplifier can be mounted directly to a wall, and further reduces operational costs with increased heat dissipation and low power consumption. Technician-friendly, universal JXP-style pads are used for attenuator and equalizer functions in both directions, simplifying the increased response required out to 1.2 GHz.
