Using the generalized saddle point theorem of Liu, the author proves the existence of multiple \(T\)-periodic solutions for the second-order Josephson-type differential system \[ u'' + Au - \nabla F(t,u) = h(t) \] under more general conditions upon \(A\) and \(F\) than in previous contributions of Mawhin-Willem, C.L. Tang, J.X. Feng and Z.Q. Han, and himself.
