臺灣嘉碩科技成立于 1997 年 11 月，主力產品為表面聲波 (SAW) 元件 (主要包含射頻表面聲波濾波器、中頻表面聲波濾波器及表面聲波共振器等)、 體波 (BAW) 石英晶振 (主要包含石英振盪晶體、石英濾波器、石英晶體振蕩器、壓控石英振盪器、石英壓控/溫度補償振盪器等) 及其相關模組， 應用領域涵蓋衛星數位廣播、行動電話及基地臺、無線區域網路、衛星定位、無線藍芽、車用遙控器、胎壓感測器等3C商品。

臺灣嘉碩科技之經營團隊涵蓋摩托羅拉通訊零件部門及國內知名相關科技產業，具備豐富通訊零件設計與實務經驗， 創業伙伴有感于國內頻率元件之需求過度仰賴進口而缺乏自主性，造成通訊產業主要零組件掌握在國外廠商之窘境， 長期競爭力因而受限，因而創立以提供中、高頻表面聲波頻率元件之臺灣嘉碩科技，并于 2001 年 6 月增加銷售體波石英元件相關產品， 于2009年投資 TFE (Wu-Xi)， 增加 OCXO 產品線，落實通訊產品之完整解決方案， 期望成為客戶最佳頻率元件之伙伴。

Founded in 1997, TST's goal is to become the leading manufacturing, design and service provider for high performance communication components. The former Motorola employees who founded TST applied their extensive experiences in related device design, manufacturing and processing development to realize these goals. TST is now recognized as the leading SAW (surface acoustic wave) device supplier in Taiwan, as well as the key OEM/ODM supplier of SAW device in the world.

While firmly committed to its core strength in the manufacturing and design of the SAW devices, since early 2001 TST has expanded the span of its products and operations to cover BAW (Bulk Acoustic Wave) devices and modules (Xtal, XO, VCO, VCTCXO晶振… etc). The strategy has proven to be a successful one. With the help of its outstanding technical and management team, TST is now being recognized and earned a reputation for being a value-added overall solution provider of communication components to its partners.技術支持

In anticipating the continuous and unprecedented growth of the communication segment in Asia, in 2003, TST is setting up its new facilities in Eastern China to better serve its customers' in the region with a full span of communication components, devices and modules.
