頻率容差只有±10ppm的6G無線應用石英晶振如何生產(chǎn)的呢X1G0036310021

高頻基本音晶體需求量很大，尤其是物聯(lián)網(wǎng)行業(yè)的無線應用。我們越來越經(jīng)常地發(fā)現(xiàn)設備通過無線電相互通信和交換數(shù)據(jù)，例如通過藍牙、ZigBee或ISM。所有這些無線電標準都使用三位數(shù)兆赫或千兆赫范圍內(nèi)的頻帶。為了產(chǎn)生這些射頻頻率，這些器件需要非常精確的參考晶體，其頻率范圍約為20至52兆赫。
無線行業(yè)的要求:超薄和高精度

具有如此高諧振頻率的石英晶振必須是超薄的。石英越厚，其頻率越低，越不適合無線應用。

生產(chǎn)足夠薄的石英盤需要一系列的生產(chǎn)步驟。原始晶體塊逐漸被分成更小的單元。最小的單元最終是“坯料”，它被鋸、磨、蝕刻和拋光以產(chǎn)生正確的厚度和特別光滑的表面。例如，為了生產(chǎn)諧振頻率為40兆赫的石英坯件，石英盤的厚度必須僅為41.5微米。

由于其額定頻率為40兆赫，這種石英盤已經(jīng)非常適合無線應用；但事情沒那么簡單。除了相當高的標稱頻率之外，還需要ppm范圍內(nèi)的最小誤差容差(ppm =百萬分之一)。這種高精度是必要的，因為各個通道的無線電頻率彼此非常接近，尤其是在高頻范圍內(nèi)。如果要避免不同無線電頻率的重疊，必須確保基本參考頻率的最低頻率容差。

這對晶體生產(chǎn)提出了挑戰(zhàn)，這可以用40兆赫晶體的例子來說明。如上所述，石英盤理想地具有正好41.5微米的標稱厚度。由于目標誤差容差僅為±10 ppm，實際值可能與理想值相差最大±0.415納米。這不到百萬分之一毫米。

這種亞納米范圍的精度不能僅通過機械生產(chǎn)步驟來實現(xiàn)。石英制造商對這個問題的反應是，根據(jù)生產(chǎn)設備的特性，從一開始就將他們的晶體生產(chǎn)得過厚或過薄。然后對晶體進行微調(diào)，以實現(xiàn)所需的標稱頻率。

微調(diào):后蒸發(fā)或離子轟擊

石英生產(chǎn)中的最后加工步驟之一是在石英盤的兩面上施加電極。該電極對于電激勵坯件的振蕩是必要的。同時，這個電極也是下面兩個微調(diào)石英過程的起點。

1)后蒸發(fā)/濺射:

為了能夠使用后蒸發(fā)工藝(也稱為“濺射”)，石英盤被制造得稍微太薄，以至于即使在施加電極之后，諧振頻率也不會太高。為了糾正這一點，石英電極上蒸發(fā)了銀。通過這種方式，應用了超薄銀層，這增加了石英的質(zhì)量并降低了其頻率。在此過程中，石英盤的頻率被連續(xù)測量。如果達到所需的標稱頻率，后蒸發(fā)立即停止。

2)通過離子轟擊進行調(diào)整

制造的石英盤稍微太厚的先決條件意味著即使在施加了電極之后，諧振頻率仍然稍微太低。在這種情況下，通過用足夠高能量的離子進行目標轟擊來減少電極的質(zhì)量。通過減少質(zhì)量，頻率不斷增加。與濺射一樣，在整個過程中監(jiān)控頻率。一旦達到期望的標稱頻率，該過程就結(jié)束。

適合所有無線應用的愛普生晶體

由于這兩個微調(diào)過程，超薄和高精度晶體可以制造各種各樣的無線應用，日本愛普生的有源晶振也是以這種方式生產(chǎn)的，這些晶體的工作頻率范圍最低能達到1MHz，容錯能力僅為±10 ppm，頻率穩(wěn)定性特別高，專門設計用于無線設備。
