An existing W-band gyro-TWA is being upgraded to achieve an output power of 5 kW and a high pulse repetition rate of 2 kHz for cloud radar application. In this paper we report the latest results on the upgrade of the W-band gyro-TWA and its components. These components include input coupler, output window, corrugated output mode converter, pulsed power system and water-cooled beam dump.
