    iPhone 徹底改變了 RF 濾波器! (The iPhone Forever Changed the RF Filter)

    22:22iPhone 徹底改變了 RF 濾波器! (The iPhone Forever Changed the RF Filter)
    • When we talk about RF filters, we're referring to those with a frequency band between 100 MHz and 10 GHz.

      當我們說到 RF filter 時,我們指的是頻帶介於 100 MHz 到 10 GHz 之間的濾波器。

    • But later, the saw filter caught the industry's interest because it was a good small analog filter that worked on frequencies from 10 MHz to 1 GHz and beyond.

      但後來,SAW 濾波器因為是一個很棒的小型類比濾波器,能在 10 MHz 到 1 GHz 甚至更高的頻率上運作,引起了業界的興趣。

    • It's over 200 MHz, which is something not very common in acoustic filters.

      它超過 200 MHz,這在聲波濾波器中並不常見。

    • The blue one corresponds to 50 MHz, the black one corresponds to 100 MHz, and the red one corresponds to 200 MHz.

      藍色對應 50 MHz,黑色對應 100 MHz,紅色對應 200 MHz。

    12:35Meshtastic 真的比… 什麼都強?? - 學習速成班 Part 2 (Is Meshtastic better than… anything?? - Crash Course Part 2)
    • The next biggest barrier that I see is that people don't understand exactly how the 915 MHz band which Meshtastic uses works.

      我看到的下一個最大障礙是,大家不清楚 Meshtastic 使用的 915 MHz 頻段到底是如何運作的。

    • When marketing, they talk solely about the technical aspects of the machine and how it has a 93.7 MHz processor compared to the Super Nintendo's measly 3.56 MHz processor.

      在行銷時,他們只談論機器的技術規格,以及它擁有93.7 MHz的處理器,而Super Nintendo的處理器僅有可憐的3.56 MHz。

    • MHz: a euro frequency of electromagnetic radiation for radio and television broadcasting (GSM, etc.).

      MHz:用於無線電和電視廣播的電磁輻射頻率單位(GSM 等)。

    • 1 MHz = 1 million Hz (exponentiation): when units occur in exponentiation, such as in square and cubic forms, any size prefix is considered part of the unit and thus included in the exponentiation.

      1 MHz = 1 百萬 Hz(指數):當單位出現在指數中時,例如平方和立方形式,任何大小前綴都被視為單位的一部分,是以包含在指數中。
