Nicol et al 2008.
The twt belongs to a category of linear beam tubes such as the klystron in which the radio wave is amplified by absorbing power from a beam of electrons as it.
Based in the uk spacepath communications designs manufactures and supports a wide array of uplink amplifiers and associated equipment covering all mission critical satcom segments.
Higher order modulation types are more sensitive to nonlinear distortions tighter constellations therefore there is a tradeoff between power efficiency i e.
Hence their dimensions mass and efficiency are major contributors to the satellite s power budget and require special attention.
