PURPOSE:To attain ease of mounting and to improve the stability of an electric characteristic by mounting a microwave module adjusted compositely with an isolator and incorporated in a case. CONSTITUTION:After the microwave module 10 is connected to the coaxial isolator 4 via a connecting plate 11 and incorporated, the assembly is adjusted compositely so as to attain a prescribed characteristic. After the module 10 is inserted to a module through-hole 14 provided to an accommodating case 21, the module is mounted while being shielded to the case 21 by the connecting plate 11. Thus, it is not required to readjust, then the module is mounted easily. Since a few mechanical connecting members are used, the stability of the electric characteristic is improved. |
