Satellite Communications — TWTA
Information on TWTA
In a satellite communications transponder, power amplification is carried out with a TWTA . TWTAs are generally preferred in satellite communications to other devices such as Klystrons because they provide high gain over a wide bandwidth and have other attractive characteristics such as high efficiency and linear amplitude and phase response. In a TWTA the signals travel along a wire helix while electrons in a high-voltage beam travel through the helix and transfer their energy to the electromagnetic wave in the wire. For GEO satellite communications operation, typically 50W is required at C band and 80-120W at Ku band.
