The TA7982 Series Tower Top Amplifier system is a full-featured, high performance TTA system utilising exceptional preselector selectivity and redundant quadrature-coupled ultra low noise amplifiers (LNAs) to improve the base station receiver sensitivity performance of a network site. The TTA system comprises two components; the Tower Top Amplifier (TTA), and a Receiver Multicoupler/TTA Controller unit (RMC). The small size of these TTA units reduces tower loading, and the integral milled preselector increases the TTA's rejection of unwanted RF signals by placing all of the system's >110dB of preselector selectivity before the sensitive TTA LNAs and RMC's active circuitry.
