第五章 整體串接實測

5.3 未來方向

未來能夠進一步研究與改善的方向還有很多,像是雙頻放大器和 濾波器都還有再微小化的空間,雙頻低雜訊放大器的輸出入兩端的反 射損失必須要再改善,還有就是濾波器 Out-of-Band Rejection 的改 善,期許這個濾波器除了具有鏡像拒斥的主要功能外,能再進一步完 全取代其他 RF 濾波器的使用。其中,在濾波器的微小化方面,將 SIR 曲折變形,可以為濾波器將來要使用非對稱的架構時,帶來更多的空 間;圖 5.9 為將 finger 曲折的實例,並且經過微小化的調整,經過 模擬之後,依然能夠提供多重的帶陷,圖 5.10 為其 S21 與 S11 的模 擬圖的兩個實例,其中,帶陷可以結合在一起,來提供寬頻的拒斥需 求。

自 傳

我是陳珀彥,1977 年出生於高雄市,高中時期就讀於高雄中學,

2000 年畢業於交通大學電信工程學系,並於 2002 年 10 月役畢後,

隨即在台揚科技任職,2006 年就讀交通大學電機學院碩士在職專班 電信組,並於 2009 年 11 月加入合勤科技。

過去任職於台揚科技的工程部共有六年半的時間,負責開發的產 品主要是從 C-Band 到 Ku-Band 的收發機(Transceiver)和點對點傳輸 設備的室外機系統(P-P Outdoor unit),從事高頻電路的設計與驗 證,主要職務內容是將產品從工程試製階段,經過客戶在特性上的驗 證,最終一直帶到量產,使產品穩定生產。目前在合勤科技無線網路 的硬體研發部門擔任工程師,從事 LTE 與 WiMAX 的硬體研發工作,希 望能夠在無線的領域裡面,涉獵得更多元。

在就讀在職專班的過程中,難得能夠有機會把既有的工作經驗,

重新拿回學校來得到驗證,所以對我而言特別有意義,收獲也特別 多,在這三年在職進修的過程中,我對自己最大的期許是我必須同時 把工作、學業與家庭都照顧好,我想,這就是每個正在為人生與家庭 奮鬥的人,心中最大的理想;未來,我希望能夠在不同的工作領域裡,

得到寶貴的經驗,同時享受工作的成就感與家庭的美滿。
