Guangjie Technology was established in October 1997 in Hsinchu Science Park. It is the first professional manufacturer in Taiwan that combines thin film/thick film process technology with high-frequency passive component/module design and development capabilities. It has an excellent technical R&D team and is committed to the research and development of thin film process technology and the design and development of high-frequency component/module integration. It provides key components such as integrated passive components and high-frequency modules that meet the high-frequency and miniaturization needs of system products. It has successfully integrated passive components such as resistors/capacitors/inductors/diodes (Integrated Passive Devices, IPDs), which can be widely used in mobile personal electronic products. Anti-static and electromagnetic filtering (ESD & EMI Filter), etc.
