Tower Top Amplifiers

RFI has culminated over 30 years of knowledge and experience into the design and building of receiver multicoupling products and solutions across the world. We understand what is involved in meeting difficult challenges on congested co-habited sites, managing noise levels and providing optimised paths for both strong and weak received signals into distribution systems feeding multiple receivers. RFI has taken this experience into designing and manufacturing industry-leading Tower Top Amplifiers (TTAs) and expandable Receiver Multicouplers.

A Tower Top Amplifier (TTA) improves base station receiver performance at a communications network site by placing the base station receiver system's preselector and low-noise amplifiers close to the receive antenna(s), overcoming the increased system noise figure and receiver sensitivity degradation introduced in a communications system by the insertion loss of the coaxial feeder cables installed on the tower. These TTA products use low noise broadband quadrature amplifier designs providing excellent  third order intercept performance and inherent fault-tolerance redundancy with balanced outputs and an additional expansion port for system expansion up to 128 outputs.
