INTEGRATION METHOD AND INTEGRATION STRUCTURE FOR CONTROL CIRCUIT AND SURFACE ACOUSTIC WAVE FILTER

The present disclosure provides an integration method and integration structure for a control circuit and a Surface Acoustic Wave (SAW) filter. The integration method includes: providing a base, the base being provided with a control circuit; forming a cavity on the base; providing an SAW resonating plate, an input electrode and an output electrode being arranged on a surface of the SAW resonating plate; facing the surface of the SAW resonating plate towards the base, such that the SAW resonating plate is bonded to the base and seals the cavity; and electrically connecting the control circuit to the input electrode and the output electrode. The present disclosure may control the SAW filter through the control circuit provided on the base, and may avoid the problems of the complex electrical connection process, large insertion loss and the like due to a fact that the existing SAW filter is integrated to the Printed Circuit Board (PCB) as a discrete device.
