Embodiment Construction

[0026] Please refer to Fig. 2, which is a device integrating a surface acoustic wave filter component (SAW Filter) and a transceiver according to the present invention. The biggest difference between the present invention and the known improvement lies in the use of component stacking to complete the surface acoustic wave filter component (SAW Filter) and transceiver. device integration. The surface acoustic wave filter component can be placed on the transceiver, so the area and cost of the system originally occupied by the surface acoustic wave filter component can be saved. The technical characteristics and characteristics of the present invention are described in detail below.

[0027] Referring to FIG. 2 , a conductive layer 221 is formed on a substrate (Substrate) 21 to be electrically connected with other components. The substrate 21 can be a semiconductor substrate or a glass substrate. A transceiver 22 is placed on the substrate 21 , and the transceiver 22 and the co...

Description

technical field [0001] The invention relates to the communication field, in particular to a device and method for integrating a surface acoustic wave filter component and a transceiver. Background technique [0002] With the advancement of wireless communication technology, various mobile devices and wireless network products are constantly being introduced, and wireless communication technology starts from signal reception, frequency modulation, decoding and calculation, and then performs signal encoding, frequency modulation and transmission. Generally speaking, it is difficult to directly convert high-frequency signals into digital signals, and the circuit operation is not easy to be stable. Therefore, in the design of wireless communication systems, radio frequency (RF) systems, intermediate frequency (IP) systems and The fundamental frequency (BB) system of the signal operation constitutes. In circuit design, a surface acoustic wave filter (Surface Acoustic WaveFilter,...
