東芝推出適用於5G智慧手機的射頻開關和低雜訊放大器IC

February 27, 2020

Toshiba Electronic Devices & Storage Corporation

東芝電子元件及儲存裝置株式會社(東芝)研發出最先進的RF SOI工藝(TarfSOI™) [1 ] ,適用於5G智慧手機等移動式設備的“ TaRF11” 射頻開關和低雜訊放大器IC(LNA)。

近年來,智慧型手機和其他移動式設備的性能有所提高,在5G時代,需要更高的無線頻段頻率。但通常頻率越高,天線與接收電路之間的信號損耗就越大,因此需要具有增強特性的LNA,以通過補償信號損耗來改善接收信號品質。

東芝新推出的TaRF11,改善了目前SOI工藝技術TaRF10的射頻特性。TaRF11工藝的LNA ,其MOSFET在8GHz時的最小雜訊指數(NF [2])為0.48dB,比TaRF10降低0.3dB [3]。與現有產品相同,TaRF11可以將LNA、射頻開關和控制電路集成到單個晶片上。

東芝在子公司Japan Semiconductor Corporation採用最新的SOI-CMOS技術,從RF射頻工藝技術研發、設計和製造的整套生產流程,可確保產品快速上市。

東芝也將繼續推廣TarfSOI™工藝技術及產品性能改善,提供Wi-Fi設備、或是預計從5GHz擴展到7GHz頻段的5G手機、以及使用7GHz至10GHz頻率的超寬頻應用,更先進的射頻開關和低雜訊放大器IC (LNA)。  

應用

  • 智慧型手機
  • 無線設備,如Wi-Fi和UWB等

產品特點

  • 優異的雜訊係數::
     NF=0.48dB(最小值)@8GHz(與TaRF10相比,提高了約0.3dB)
  •  LNA、射頻開關和控制電路可以集成到單個晶片上。
  • 集最新的半導體工藝開發和產品於一體,可儘早推出高頻開關產品。
