Low Power Transmitter / Gap Filler / Transposer
The OneBox solution can be 2U high (1-30Wrms and 50Wrms) or 3U high (150Wrms and 300Wrms). The mechanical construction is extremely compact and solid in order to stand heavy duty handling and service enviromental conditions.
The electronic design is simple and compact, with minimum internal wiring. The mother board take care of the management of the Digital Modulator and the RF Power Section. The heart of the RF control are a new RF input MANAGER, specifically designed for this unit, and a new innovative Compensated Output Directional Coupler that assure a flatness response, all over the band (470-862MHz), of 0.2dB in order to avoid any manual setting.
Local control can be done via LCD and keyboard by means of a friendly software that can manage all Transmitter parameters. Remote control can be performed via Ethernet RJ-45 interface for web browser and SNMP. All OneBox units can be connected via RS485 and can dialog with the XU Power Amplifiers line, acting as a Logic Control unit for any type of high power configuration system.
