The medium power transmitters of TVH4000 series incorporate power amplifiers based on LDMOS transistors technology characterized by high power density, allowing very high efficiency. They provide excellent values on key parameters of the transmitted signal quality, such as shoulder attenuation and MER.
They integrate a modulator that covers the main Digital TV and Radio systems, equipped with the latest technology in signal processing allowing Digital TV and Radio signal broadcasting with the highest quality and reliability.
The customer oriented and compact design provides full flexibility and multiple configurations per rack, saving a lot of space in the transmitter site. The rapid and easy stratup of the transmitter and the power of the Web Server ensures fast commissioning and easy operation. The different options for redundancy and optimal design of critical modules guarantee continuity of service throughout the life of the transmitter.
