隨著電子科技的快速發展，電子科技也跟著日新月異，從貝爾發明了電話的有線通訊（1876）至今，縮短了人與人的距離，而近年來的微晶片高科技發展迅速，使得無線通訊更為普及。而無線通訊的方便性，也逐漸地取代了有線電話。 在本篇論文中，探索研究WCDMA手機，如何增加接收靈敏度，增加訊雜比，設計良好的射頻特性，以讓業者在第三代行動通訊產品的產業中增加競爭力，並深入探討其WCDMA射頻前端之設計。 Along with the fast development of electronics science and technology, electronics science and technology also follows to change with each passing day, Bell invent the wired communication phone (1876) to shorten the person and others' distance up to now, and in recent years of the microchip slice high technology develop quickly and make wireless communication more universal. The the convenience of the wireless communication are used to gradually replace a wired telephone. Thesis proposes to invest and research the WCDMA cellular phone receiver to increase it’s sensitivity, and signal to noise ratio, shorten development schedule by the proprietor, increase a competition ability in the third generation mobile communication the service of the industry, and going deep in to probe into its WCDMA the radio frequency front end the analysis of design.
