Lindsay Broadband’s exclusive, compact, multiple-dwelling unit (MDU) amplifier delivers reliable performance supporting DOCSIS
®
3.1 frequencies to 1.2 GHz.
The LMDA3726 series of amplifiers 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.
