DESCRIPTION:

Key features

 

 

The transmitters of TAE7000MP series broadcast analog TV signals in the UHF frequency band. They have a fully modular and compact design. Each of the modules that make up the transmitter is easily removable and replaceable. The transmitters provide an output power of 500W and 1KW ensuring maximum quality and reliability.

• Compact and flexible transmitter system
• LDMOS balanced power amplifier charecterized by high linearity
• High performance and realiability power supplies
• 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
• Highly stability and high resolution local oscillators synthesized via PLL with DDS technology
• High stability internal frequency reference. GPS synchronization
• Parameters control via display
• PC graphical interface
• Linear and non linear precorrection through keyboard/display and PC
• Possibility to integrate the output filter in transmission rack
• Possibility to add a second audio/Nicam
• Central control unit for monitoring major parameters of the transmitter and alarm detection, allowing N+1 configurations
• Log alarm system in the control unit
• Main alarms available by leds
• Remote interfaces: parallel interface and SNMP (optional)
