Traveling-wave tube - Wikipedia
A traveling-wave tube (TWT, pronounced "twit" [1]) or traveling-wave tube amplifier (TWTA, pronounced "tweeta") is a specialized vacuum tube that is used in electronics to amplify radio frequency (RF) signals in the microwave range. [2]
TWTA vs SSPA | Difference between TWTA and SSPA
TWTA stands for Travelling Wave Tube Amplifier and SSPA stands for Solid State Power Amplifier. The other difference between terms are provided here. As we know amplifier is a device which increases current, voltage or power of signal provided as its input.

2020年6月5日 · The first TWTA flew on a satellite in 1962, and they have been a part of every science spacecraft NASA has launched since 1972. L3 is the only provider of space certified TWTAs in the United States, and they have been continually working with NASA to improve their performance over the past 50 years.
In this study, we review current TWTA and SSPA technologies available for space-based applica-tions and discuss future planned technologies. We begin by summarizing and comparing five previous studies of amplifier technologies. Then, we analyze trends in TWTA and SSPA technologies using
Downlink TWTA and V-and 200 W Uplink TWT to better serve the high-throughput satellite market. The key to a higher throughput satellite for these operators is a higher-power, wideband downlink signal. We are reshaping the TWTA market by introducing new, revolutionary technologies to accommodate Q-/ V-band needs.
recognize that phase shift caused by the TWTA is lesser of the two evils. Most of the degradation comes from the amplitude non-linearity effects of the TWTA. If the envelope of the signal (its outline) is fairly constant, then the TWTA amplitude gremlins are likely to go hungry but if the envelope fluctuates, they have a feast.
