LA35Rx Series 1 GHz Compact MDU Amplifiers
Installation Manual
Page 1 of 4
Lindsay Broadband’s LA35Rx compact, multiple-dwelling unit (MDU) broadband distribution amplifier is a full-featured, 2-way, 1 GHz indoor station wth superior
distortion characteristics and low noise.
It is a tough, indoor MDU amplifier specifically designed for broadband distribution systems in apartment buildings, hotels, schools, hospitals and other similar facilities
requiring RF amplification where high quality, low noise figure amplifiers are necessary in both forward and return paths.
Compact in size and designed to mount directly to a wall with increased heat dissipation and low power consumption, this amplifier runs cool and reduces operational
costs. GaAs E-pHEMT push-pull technology provides superior distortion performance and low noise to 1 GHz in both the forward and return paths. It has flat
operational gain of 35 dB in the forward path and 18 dB in the return path. This amplifier also has an input variable EQ and plug-in mid-stage equalization feature in the
forward bandwidth for balancing, a forward 20 dB input gain control, and 20 dB input and output reverse gain controls.
