Tower Top Amplifiers
At some radio communications sites, base station receivers are located a relatively long distance from the receiver antenna. This is common at larger macro sites with tall towers or where the antenna is on a building's rooftop and the radio equipment is in the basement. Longer coaxial cable runs between the receiver antenna/s and the base station receivers may negatively affect the receivers' sensitivity due to increased noise figure caused by the high insertion loss of the cable, especially at higher frequency bands such as 700/800/900MHz.
RFI's Tower Top Amplifiers (TTA) provide a solution to overcome this sensitivity degradation by placing the base station receiver system's preselector and low-noise amplifier close to the receiver antenna/s.
Our TTAs use low noise broadband quadrature amplifier designs providing excellent third order intercept performance and inherent fault-tolerance redundancy.
