Miniaturized surface acoustic wave filters are mostly used for consumer electronics, but not for vehicle systems. Because the specifications of automotive products require much higher environment or precision, reliability and durability than those of consumer electronics, the design of wafer specifications, the selection of materials or the technology of manufacturing process are quite severe challenges and tests. Taking this product as an example, it is applied to the latest 4.5-generation vehicle-borne digital satellite broadcasting system with a size of 1.4mm x 1.1mm x 0.7mm. It is the most advanced and minimal surface acoustic wave filter with metal packaging on the market. In addition to its low-loss, high-sideband noise suppression capability, it also uses advanced special architecture and process technology to make the product world-class in precision and reliability, and has the advantages of both light and small size, which is no inferior to the international large factories. Some specifications and characteristics exceed the technical level of the same industry and make Taiwan Jiashuo stand out as a world-class leading factory. The list of businessmen.
In order to be close to the market trend and development of portable devices (smart phones, tablets, wireless audio and video products and personal navigation devices), wearable devices (smart glasses, watches, hand rings and personal sensors) and devices related to the Internet of Things (smart meters, smart cards, RFID tags and smart homes), and to meet the needs of consumers for related products, terminals Businessmen are all moving towards multi-functional integration, low power consumption and small device size. Therefore, for the frequency components used in the above types of products, the required frequency accuracy and volume minimization are increasingly stringent. The Ring Wall Type series of frequencies of quartz oscillator with a length/width/height of 1.6mm x 1.2mm x 0.32mm developed jointly with Japanese professional ceramic base manufacturer can fully meet and meet the development requirements of this type of device. Its main advantage is that the volume of the frequency components can be reduced again, and the height of the frequency components can be reduced by nearly 30% compared with the traditional packaging products of the same type, which directly improves the diversity and selectivity of the matchable terminal products, and its electrical characteristics are no less than the larger size quartz oscillator, but the appearance size is smaller.
This series of products have been developed in full frequency range from 24MHz to 52MHz, which can meet the wide needs and applications of different types of terminal customers. At the same time, it has also sent samples to many IC design companies, R&D centers and manufacturers in related industries, with a wide range of customers all over the world, including Taiwan, China, the United States, Japan and several European countries, many of which have been more successful. Through rigorous customer certification, complete product performance testing and reliability testing, and begin to receive customer research and development orders. I believe that in the near future, this product will be favored and adopted by most customers, creating a win-win situation for both sides.
