Abstract
The measurement and adjustment of characteristics of a filter alone are performed using a connector adapter, in which a pin of the filter becomes a central conductor of the adapter. The filter after the adjustment and a device which is not adjusted are assembled, such that the filter and the device are connected by connecting the pin provided in the filter and a transmission line provided in the device. Accordingly, the time for adjustment is shortened and the adjustment for obtaining the desired characteristics of the filter module are made easy.
Claims8
A manufacturing method for a filter module containing a device, characteristic measurement of which has been made, and a filter, characteristics adjustment of which is to be made, the method comprising:
- determining required characteristics of the filter from the characteristic measurement of the device and target characteristics of the filter module;
- measuring characteristics of the filter alone;
- making characteristic adjustment of the filter such that adjustment locations and adjustment amounts for meeting the required characteristics of the filter are determined from the characteristics of the filter alone and the required characteristics;
- and
- combining the filter, the characteristic adjustment of which has been made, and the device by connection thereof.
