The invention relates to an LTCC-based miniaturized tile type T/R assembly. By means of a conventional medium material, through reasonable layout of a microwave chip, a microwave transmission line and a control signal line, the miniaturized tile type T/R assembly which has a dimension of 9 mm * 9 mm * 4.3 mm, has high integration and facilitates conformation. The LTCC-based miniaturized tile type T/R assembly solves the problems of large dimension and difficulty in actual application and the like of a conventional T/R assembly, enables the T/R assembly to have higher integration, enables a current phased array to have the advantages of miniaturization, conformal to environment and the like, and satisfies the demands of special platforms such as a vehicular-mounted platform and the like.
