Abstract
The Horizon 2020 TWEETHER project aims to a breakthrough for the new generation of high data rate wireless networks, introducing for the first time millimeter wave traveling wave tubes (TWTs) as enabling devices. TWT is the only device able to provide adequate transmission power for wireless distribution of the internet signal in a wide area. The frequency range 92 – 95 GHz is a light licensed portion of the spectrum, with about 3 GHz available bandwidth for point to multi point distribution. However, the millimetre wave frequency range poses formidable challenges for design and fabrication of TWTs with low cost and long lifetime, suitable for the wireless market. The paper will describe the design and the fabrication challenges to achieve the required 40W output power in 92 -95 GHz frequency band.
