Traveling wave tube for broadcast satellites
Abstract
The development of an advanced traveling wave tube (TWT) for broadcast satellites is described. TWT is an electron tube which functions at the heart of such satellites by amplifying and beaming microwaves to Earth. The new TWT features power of more than 120 watts, a power gain of 43 decibels (decibel being a unit for measuring relative loudness sound) and total efficiency exceeding 45 percent strict requirements of broadcast satellites.
