One of the challenging technologies of ADS is the high availability requirement. The availability design of the solid-state amplifier is the preparation for ADS. Firstly the availability requirement of CiADS is proposed as 0.8. The distribution result of the solid-state amplifier is 0.999 according to this requirement. Then the availability result shows the preliminary design of solid-state amplifiers can not reach the availability requirement. At last the power loss is considered to build the k/N redundancy model of the main amplifier and the mean time between failure (MTBF) is calculated for various redundancy models. The reliability block diagram of the solid-state amplifier is set up by Reliasoft and the simulation results show that the 25/28 redundancy model can meet the requirement 0.999 when MTBF of other components reaches 171 702 hours with the certain maintenance.
