RETRACTED: Highly Integrated Control Technology of Flexible LTWTA for Space Application (Retracted Article)

A highly integrated control technology for Flexible Linearized Travelling Wave Tube Amplifier (LTWTA) is proposed in this paper. This control technology has flexible and complete functions to achieve accuracy control effects, especially for the power adjustment range, which could be up to 3dB with 64 steps. Control module is optimized to fit response of TWT and to ensure drive security across the full flexible range. Moreover, the System In Package (SIP) circuit is designed to integrate nearly twenty chips and hundreds of resistors and capacitors, this distinct integrated package in control module realizes the miniaturization of the LTWTA product.
