Microwave digital device

Structure not enough of data signal and ground signal separation is carried out to traditional microwave digit composite substrate, the utility model provides a microwave digital device. Microwave digital device, including compound circuit board and metal casing, be equipped with the back drilling blind hole on the bottom surface of compound circuit board, the metal casing is glossy plane towards one side of compound circuit board, and the metal casing is not equipped with the blind hole towards one side of compound circuit board promptly. Profitable technological effect: the utility model discloses avoided the processing to the metal casing, more convenient than the processing of old structure, overall processing cost is lower, and machining efficiency is higher. 针对传统的微波数字复合基板进行数字信号与接地信号分离的结构的不足，本实用新型提供一种微波数字装置。所述的微波数字装置，包括复合电路板和金属壳体；在复合电路板的底面上设有背钻盲孔；金属壳体朝向复合电路板的一侧为光滑的平面，即金属壳体朝向复合电路板的一侧不设有盲孔。有益的技术效果：本实用新型避免了对金属壳体的加工，比老结构加工更方便，总体加工成本更低，加工效率更高。
