LINDSAY RF MULTI-DWELLING AMPLIFIER

PRODUCT OVERVIEWThe Lindsay exclusive mul!ple dwelling amplifier delivers reliable performance suppor!ng DOCSIS®3.1

frequencies to 1.22GHz. The unique design allows for seamless upgrade configura!ons from 42/54, 85/102 and

204/258 by simply exchanging filter sets- futureproofing upstream bandwidth requirements.

Model LHA38-RMA applica!ons for advanced HFC network installa!ons in apartment buildings, hotels, schools,

hospitals and similar facili!es having high RF amplifica!on requirements. Designed with high gain, this amplifier

can be mounted directly to a wall with increased heat dissipa!on proper!es and low power consump!on. This

amplifier runs cool reducing opera!onal costs. The ul!mate two-way upgradeable amplifier uses the latest

1.22GHz GaAs-Fet Push Pull technology providing superior distor!on performance and low noise. Technician

friendly on board unique equalizers enable equaliza!on and slope setup with simple resis!ve a#enuators,

greatly reducing opera!onal expenses.

FEATURES• Wall mount aluminum die-cast

• Heat dissipa!on finned design

• Opera!ng temperature range -30°C to +55°C

• 38dB forward gain, 24dB reverse gain

• JXP type resis!ve a#enuators unique control

• -20dB external test points

• Surge protected to 6kV on all ports

• HFC 40-90 VAC; 48 VAC; 15 VDC & 100-240 VAC

powering op!ons

• Seamless upgrade 42/54, 85/102 and

204/258 MHz for easy switching between DOCSIS®3.0 to

DOCSIS®3.1
