Receiver Multicoupler/TTA Controller unit (RxMUX) 690-960MHz, 8 PORT MULT With TTA Control -48VDC

The TTA7982-0100-10-00 Tower Top Amplifier is a full-featured, high performance system utilizing a quadrature-coupled Low Noise Amplifier (LNA) design to improve the performance of a network site. The TTA system comprises two components; the Tower Top Amplifier (TTA), and an RX6996-3001-36-xxN Receiver Multicoupler/TTA Controller unit (RxMUX) that intergrates into a Motorola GTR800 ESS system.

SKU: RX6996-3408-38-48B Category:

The Tower Top Amplifier is designed and built for ease of mounting to varying size tower legs using commonly available fasteners with a compact and integrated precision milled high selectivity low loss preselector, reducing the TTA profile and hence tower loading. Two independent LNA’s, with an auto by-pass mode and constant monitoring provide system redundancy, resilience and improved availability. Low noise linear amplifiers provide excellent Inter-Modulation (IM) performance ensuring maintained integrity of received signals across a wide signal amplitude dynamic range.

The precision milled and integrated TTA preselector provides >110dB of selectivity before the TTA LNA and RxMUX active circuitry. A comprehensive microprocessorcontrolled status and fault monitoring system provides continuous monitoring and switching of the redundant LNAs.

Ease of installation and configuration via user-friendly switches or an onboard web server and GUI interface, reduces installation setup time. Unique “auto-gain” feature provides an additional level of failure tolerance. Test port functionality facilitates the Motorola 5 step plan for commissioning and Performance Logging ensures that ongoing optimum system performance is measurable. Front and rear panel LED indicators and Form-C relay fault reporting with the simplicity of local or remote system status diagnostics via the Ethernet port greatly assists in determining network health and pro-active maintenance. The RxMUX features selectable in-line Post filter connections to facilitate additional
