Tower top amplifiers
700MHz-800MHz
Dependable performance for mission critical applications
Filtronic’s TTA systems are fully compliant with the most stringent public safety RF specifications. The amplifiers have excellent system flatness across the passband and low system noise figure while retaining linearity and out-of-band rejection. This provides optimum inbound coverage and dependable performance in mission-critical applications.
The Tower Top Amplifier (TTA) is a crucial component in the majority of network base stations. It is used to improve receiver performance. TTAs incorporate a low-noise amplifier installed at the top of the mast and a control/distribution unit installed at the base. The tower-top element incorporates a low-loss, bandpass filter to protect the receiver from out-of-band interference and a low-noise amplifier to boost the received signal.

Product description
Filtronic’s Tower Top Amplifiers (TTAs) feature smart redundancy, which continuously monitors the health of the balanced quadrature-coupled amplifiers. In the case of a failure in one of the amplifiers, the system can continue to operate using the redundant amplifier. If both amplifiers are lost the system will function in a bypass mode.
The TTA system features gain flatness across the band typically less than 0.5 dB, third order intermodulation of greater than +13dBm, noise figure of typically less than 2.5dB, and a high-performance preselector filter. This gives radio system operators the confidence knowing their mission-critical networks will reliably operate with resilient connections and higher quality audio, especially in congested environments.
A complete, receive signal tower top amplifier system designed for 700 and 800 MHz communication networks.
The compact TTA units measure approximately 9 x 6.8 x 2 inches (229 x 173 x 51 mm) and weigh less than 3.6kg (8 lb.). The space saving 1RU rack-mounted control units have model options with eight output ports, expandable to either 16 or 32 ports using optional expansion kits.
