SMARTop Tower Top Amplifier System

The main purpose of a tower top amplifier is to amplify the receive (uplink) signal before the long cable drop from the tower top resulting in a substantial increase in receive sensitivity and overall coverage. SMARTop Tower Top Amplifiers (TTAs) accomplish this by using a highly advanced, balanced, single-stage low noise amplifier (LNA). Reliability in extreme conditions can be further supported with an option with redundant LNA on many versions.
ADC has designed the TTA System with integrated lightning protection. The Masthead Unit and the Base Unit house built-in quarterwave lightning arrestors at the interface ports (antenna and base station) as well as high quality gas tube lightning arrestors at the feeder cable ports.
ADC's product offering includes SMARTop™ RX450, RX800, DD800, DD900, DD1800, DD1900 and DB1800 Tower Top Amplifier systems.
