Product Description


UBS’ Ka-Band amplifier system is designed using a highly efficient, cost-effective travelling wave tube (TWT). It provides 300W (54.8 dBm) min. of flange power over an operating frequency range of 27.0 to 31.0 GHz. The modular design includes an input signal distribution system, two (2) TWTA modules and an output power switch, allowing the system to switch between TWTA modules. All are located in a weatherproof housing, suitable for outdoor antenna mounting.


The TWTA module is built as a self-contained unit and contains an integrated air cooling system. Two (2) TWTA modules are configured to provide a minimum flange power of 300W (54.8 dBm) with full redundancy. The optional, indoor control cabinet, with system controller, dehydrator and/or PDU, provides a convenient means to power and control the TWTA system. The system controller is responsible for the configuration and management of the entire TWTA system and provides user interfaces for local and remote control.
