435 Series, Mini Tower Top Amplifier System (TTA) is designed to enhance the operation of the base station. The TTA increases receive sensitivity, reduces transmit signal interference and can make all the difference in Mission Critical Communications.

The TTA system consists of two components: the Tower-Top Amplifier mounted close to the antenna and a Receiver Multicoupler base unit. To reduce the size of the TTA and simultaneously provide 120 dB of isolation of a TX carrier, filtering has been split between the TTA and Receive Multicoupler base unit.

The tower mounted unit is housed in a compact light weight, weather resistant enclosure. The internal electronic components are protected from lightning by surge arresters on all RF ports. The system is designed for quick and simple installation.

Industry leading TTA amplifier linearity guarantees superior immunity to intermodulation interference.

FEATURES

• Quadrature-coupled low noise amplifier (LNA) improves RX sensitivity.
• PolyPhaser™ impulse suppressors provide protection from lightning damage.
• High performance filtering in tower top and base control unit.
• Wind loading is reduced due to small enclosure size.
• Quick installation.
• Compact, light weight, weather-resistant enclosure.
• One rack-unit high 8-Port Receiver Multicoupler (MCU).

APPLICATIONS
The TTA is designed to increase the performance of a Base Transceiver Station (BTS) while ensuring reliable communications for critical Public Safety applications. This increase in sensitivity can make up for the imbalance between mobile and handheld users in critical systems.

Tower Top Amplifier will function up to 70°C without shutting down however, the specifications are not guaranteed outside the rated temperature range.

A steep skirted TEM bandpass filter in the tower box augmented by a ceramic filter in the base unit provide a selective 32 MHz system window.
