Abstract: Solid state power amplifier module plays a key role in full solid state transmitter system. The assembly technologies of the module have important influences on the comprehensive performance of phased array radar. As a result, S-band solid state power amplifier modules place high demands on the assembly, soldering and testing in batch production. In this paper, the realization of automatic assembly and testing are discussed,the feasibility of adopting automatic production line for solid state power amplifier modules are verified. The application of the research results enhances the assembly consistency and reliability of power amplifier modules efficiently and lays a good foundation for the development of industrial intelligent manufacturing.
