Abstract :
Three different kinds of circular waveguide taper are designed for a Ka-band two-cavity gyroklystron amplifier, which are radially shaped to follow a Dolph-Chebyshev profile, a Modified Dolph-Chebyshev Profile and a linear profile respectively. With almost the same taper length, the amplifier using the taper following the Modified Dolph-Chebyshev profile has the appropriate mode conversion and meets the desired performance.
