LBA3827 1.2 GHz MDU Amplifier

The Lindsay exclusive multiple dwelling amplifier delivers reliable performance supporting DOCSIS® 3.1 frequencies to 1.22GHz. The unique design offers configurations for 42 and 85MHz upstream bandwidth requirements.

Model LBA3827 applications for advanced HFC network installations in apartment buildings, hotels, schools, hospitals and similar facilities having high RF amplification requirements.

Designed with high gain this amplifier can be mounted directly to a wall with increased heat dissipation properties and low power consumption, this amplifier runs cool reducing operational costs. The ultimate two-way amplifier uses the latest 1.22GHz GaAs-Fet Push Pull technology providing superior distortion performance and low noise. Technician friendly controls feature variable attenuators and equalizers facilitating greater flexibility when adjusting the amplifier. The mains powered automatic switching mode power supply accepts input voltages from 90-240 V at frequencies of 50 or 60Hz without adjustment.
