摘要: <正> 行波管放大器是通信、广播卫星的关键部件。大功率行波管放大器的可靠性是整个直接广播卫星领域的中心课题。国外在行波管研制、行波管电源研制、行波管寿命试验和失效机理研究方面已经投入了很大的力量。另一方面,对于卫星上行波管放大器冗余方案的设计也引起了普遍的关注。
Abstract: The reliability of TWTA is a central issue in the field of communication and broadcast satellite. In order to increase the reliability, the TWTA redundancy can be introduced. It can be shown that the cross-strapping redundancy is better than the redundancy individually for each channel. In this paper, the formule for the reliability of n:k "cold" cross-strappinp redundancy system is discussed, and that of n : k "warm" cross-strapping redundancy system and its approximete form when η≤0.1λ are prfsented.
