PURPOSE:To prevent the cracking and breakage due to a temperature stress and to make the impedance matching easy, by forming metal conductors which are terminals of a microwave transistor on the surface of a package. CONSTITUTION:In a microwave transistor 13, metal conductors 9, 10 of the terminals are formed on the surface of a package 15. To connect the transistor 13 to MIC substrates 2, 3, first the microwave transistor 13 is screwed between the MIC substrates 2, 3 attached to a case 1 using a male screw 14. One end of metal ribbons 11, 12 is soldered to the conductors 9, 10 of the transistor 13, respectively. Finally, the ribbons 11, 12 are bent, and the other end of the ribbons 11, 12 is welded or soldered to the film circuit patterns 4, 5 of the substrates 2, 3, respectively. With this, the cracking and breakage due to a temperature stress are prevented, whereby the impedance matching becomes easy.
