A radio module comprises a top board (110) with all components mounted on a front surface (111) and a metal substrate on a back surface (112); a bottom board (120) with all components mounted on a front surface (121) and a metal substrate on a back surface (122) wherein the bottom board (120) is arranged so that the front surface (121) of the bottom board (120) is opposite to the front surface (111) of the top board (110); and at least one shielding board (130) provided between the top board (110) and the bottom board (120) with certain vertical spacing. The top board (110) the bottom board (120) and the at least one shielding board (130) are arranged to be substantially in alignment in a vertical direction and be fastened with one another. A board board electrical connection (140-1,140-2) is established at least between the top board (110) and the bottom board (120). |
