The deployment of HTS is one of the biggest drivers in the satellite market…It’s not just Ka-band, services but Ku-band as well. As these new HTS systems are deployed around the world, they flood the market with capacity. Satellite is no longer the connectivity option of last resort.” –Brendan MurrayWASHINGTON, DC – Increasingly improved amplifier technology in the satellite market has made possible the transmission of higher and higher amounts data from High Throughput Satellites (HTS), satellite terminals, and other advanced networks. Of those amplifier technologies currently available, TWTAs have long been considered to offer raw power advantages over Solid State Power Amplifiers (SSPAs), beyond 20 GHz. However, recent advances of gallium nitride (GaN) transistors have allowed manufacturers to offer SSPAs that “operate at higher frequencies and produce higher output power.” Even as SSPAs become smaller and more efficient, TWTAs have improved as well, which is good news for HTS, as network designers are considering how to deliver terabytes of throughput.
Senior research analyst Brendan Murray “points out that HTS systems have an expanded gateway architecture and require more gateways than FSS networks. He highlights the NBN system in Australia as an example: it has only two high throughput satellites but 10 gateways, which address only 3 percent of the underserved population in the country. To reach more subscribers, more gateways will be needed, driving future demand for RF amplifiers.”
