Signal linearisation is critical within satellite uplink amplifiers, writes Rohde & Schwarz Vice President Transmitter and Amplifier Systems Cornelius Heinemann.
We live in interesting times. Without doubt, the broadcast and electronic media industries are becoming more IT-centric and the influence of internet protocol (IP)-based workflows is increasing. These technologies are enabling the distribution of high quality content over a myriad of smart devices at quality levels that would have been unimaginable just a few years ago.
However, there is still a critical need to distribute the same content to a large audience and in this scenario, satellite and terrestrial transmission architectures continue to play mission critical roles. As we witnessed at this summer’s FIFA World Cup finals in Russia, a single event (or match) can attract worldwide audiences that are measured in billions.
For the foreseeable future, satellite and terrestrial transmission systems are an absolute requirement of any broadcaster’s technology infrastructure. These are markets where Rohde & Schwarz has a long and very successful history. Yes, we are focussing on new IP-based production strategies but at the same time we will never lose our focus on pushing the boundaries of terrestrial and satellite communication. As consumer tastes evolve around HD and UHD standards, terrestrial and satellite broadcasters face the challenge of carrying far greater amounts of data across their networks.
Satellite uplink amplifiers
With our rich heritage in broadcast, we are continually seeking for new opportunities where we can leverage on our experience in designing and manufacturing high power transmission equipment for demanding 24/7 applications and new satellite-based markets to establish. One critical area of satellite technology is the amplifiers which are used within ground-based equipment to uplink signals to satellites.
At Rohde & Schwarz, we have a proven track record stretching over more than six decades in the field of high power RF amplifier design. Our products were initially designed for terrestrial transmission applications but the portfolio has been successfully widened to include a diversity of applications including communications, scientific, EMC and design and product validation.
The reason for our entry into the satellite uplink amplifier market today is the…
