1.2 GHz MDU Amplifier (LBA-3827 Series)

This Lindsay Broadband exclusive multiple dwelling unit (MDU) amplifier delivers reliable performance supporting DOCSIS® 3.1 frequencies to 1.2 GHz. The unique design offers configurations for 42, 85 and 204 MHz upstream bandwidth requirements. The LBA-3827 amplifier is suited for applications for advanced HFC network installations in apartment buildings, hotels, schools, hospitals, and similar facilities having high RF amplification requirements.

This high-gain amplifier can be mounted directly to a wall. It runs cool with its increased heat dissipation properties and low power consumption, thereby reducing operating costs. The two-way amplifier uses the latest 1.2 GHz GaAs FET push-pull technology, providing superior distortion performance and low noise. Technician-friendly controls feature variable attenuators and EQs 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 60 Hz without adjustment.
