Assembling and checking microwave circuit modules is accomplished by storing results of checks of active elements after the manufacture, determining (5) a combination of active elements according to the stored results or data, calculating (6) the characteristic value of the determined combination according to the results of checks of the active elements in the combination, computing (7), if the calculated characteristic value is out of a predetermined range, a content and an amount of adjustment to be made in a substrate so as to correct the characteristic value to be in the predetermined range, and adjusting (9) the substrate according to the result of computation (7). By selecting an appropriate combination, the chips whose characteristic value falls outside of the predetermined range are saved from being discarded, so that a low cost microwave circuit module can be obtained at a high overall yield. <IMAGE> |
