The invention discloses a symmetric integrated stacked transformer. The symmetric integrated stacked transformer comprises a substrate, a first layer of medium, a second layer of medium and a third layer of medium, which are arranged on the substrate from bottom to top in sequence, a latticed shield grid, which is positioned in the first layer of medium, a primary coil, which is positioned in the second layer of medium, and a secondary coil, which is positioned in the third layer of medium, wherein the shield grid is arranged on the lower plane of the first layer of medium; the primary coil is formed by parallel connection of two circles of square micro-strip coils, which are separated with each other and are symmetrical around the axis, and is arranged on the lower plane of the second layer of medium; the secondary coil is formed by series connection of fives circles of square micro-strip coils, which are separated with each other and are symmetrical around the axis, and is arranged on the lower plane of the third layer of medium; the adjacent coils in pairs are crossly connected with each other at the places close to the axis through two connecting lines, one remaining circle of the coil is directly connected at the place close to the axis through the connecting line of the same metal layer, and a center tap of the secondary coil is arranged on the middle point of the coil. The symmetric integrated stacked transformer has the characteristics of good symmetry, high rate of turn and high magnetic induction coefficient.
