DESCRIPTION:

Key features

 

 

The transmitters of TAE9000MP series broadcast analog TV signals in the UHF frequency band. The power amplifiers are based on LDMOS-50 volt. technology characterized by high power density, allowing very high performance. These devices have a fully modular design and reduced size. Each of the modules that make up the transmitter is easily removable and replaceable. The transmitters provide an output power of 750W, 1.5KW, 3KW, and 5.7KW, ensuring the maximum quality and reliability.

• Power amplifiers based on LDMOS-50 volt technology with high power density
• High energy efficiency
• Compact and flexible transmitter system
• High performance and reliability power supply integrated in power amplifiers
• Optionally it is possible to include a redundant one (In single phase supply voltage)
• Cooling system by forced air
• Continuous frequency tuning between 470 and 862MHz without readjustments
• IF/RF converter with two fixed intermediate frequencies (double conversion) for high spectral purity
• High stability internal frequency reference. GPS synchronization
• Highly stability and high resolution local oscillators synthesized via PLL with DDS technology
• Parameters control via display
• PC graphical interface
• Linear and non linear precorrection through keyboard/display and PC
• Log alarm system in the control unit
• Main alarms available by leds
• Remote interfaces: potential-free contacts, SNMP (optional)
