The major subjects of RF window design for high average power gyroklystron amplifiers are to reduce the reflectivity and absorption power in order to enhance amplifier's stability and protect output window. In this paper, the window's reflection and absorption are analyzed in detail. As an example, a sapphire window of 9mm in diameter and 1.351mm in thickness for 10kW, 34GHz, TE01 gyroklystron amplifier is presented. Its reflectivity is less than 1% if process error is within 2%, and its absorbing power is about 2.5W while the output average power is 10kW. As the window's reflectivity is sensitive to its thickness error, the thickness must be strictly controlled in processing．
