Apparatus and method for assembling and checking microwave monolithic integrated circuit (MMIC) module

A method for manufacturing a microwave circuit module having a plurality of active elements mounted on a substrate, said method comprising the steps of:

• checking characteristics of all active elements immediately after their manufacture;
• storing, in a memory, results of checks of the characteristics of the active elements with said results being stored individually in correspondence to said active elements;
• determining a combination among said active elements according to said results of checks in the memory such that a characteristic value of the combination among said active elements results in a predetermined range;
• calculating a combined predicted characteristic value of said combination according to said results of checks of the characteristics of the active elements determined;
• computing, when said combined predicted characteristic value obtained in said calculating step is outside said predetermined range, a content and an amount of adjustment to be made in said substrate for said combined predicted characteristic value to be in said predetermined range;
• processing a substrate according to results obtained in said computing step;
• and
• assembling the active elements in said determined combination on said substrate having been processed.

The method for manufacturing a microwave circuit module according to claim 8, further comprising the steps of:

• checking a module characteristic value of the microwave circuit module assembled in said assembling step;
• analyzing a deviation of said module characteristic value from said predicted module characteristic value of said microwave circuit module obtained in said detecting step;
• and
• feeding back results of the analysis of the deviation to the step of determining the combination among the active elements.
