射頻光纖模塊用于將射頻信號轉為光信號,通過光纖傳輸,接收端再將光信號轉換成射頻信號,其距離長、帶寬高、響應平坦,使用于通信及雷達系統。衛(wèi)星通信中,點到點的天線可以通過此設備將射頻信號轉為光信號,通過光纖連接至幾米到幾千米的控制室外。廣播信號也可以將RF信號轉為光信號通過光纖傳輸。雷達系統可以通過此方式將雷達天線和信號室進行遠距離連接。射頻光纖模塊根據帶寬的不同,有8GHz,15GHz,20GHz不同射頻帶寬的產品,另有3GHz, 2.4GHz, 1.5GHz等低頻段,根據需要,可選擇單向和雙向傳輸系統。
The RF over fiber transmission module FT-AH-ROF120M designed for RF/wireless signal transmission over long distance, which overcome the problem of high loss when the RF/wireless signal transmit over coaxial cable or free space.
