功率噪聲發生器方案:
Noise generator power plan:
A1,A2,A3可采用OPA843或OPA846(美國德州儀器有限公司)的運算放大器,每級放大器設計為40dB.每級之間需屏蔽隔離,電源需進行嚴格退藕.A4為輸出放大器,增益可為0dB,但具有較強的驅動能力,可采用高頻甲類大電流放大(或跟隨),也可采用互補輸出形式,“B”為寬帶阻抗匹配變壓器,帶寬為50Hz-10MHz。
A1, A2, A3 can use OPA843 or OPA846 (Texas instruments co., LTD.) of the operational amplifier, the amplifier design is 40 db per level. The need to shield placed between each level, the power supply should be strictly lotus root. A4 for the output amplifier, gain can be 0 db, but has the strong ability of driving, can adopt high-frequency class a large current amplifier (or with), also can use complementary output form, the "B" for the broadband impedance matching transformer, 50 hz - 10 MHZ bandwidth.
XO4O 選購件: X040噪聲同軸輸出頭:600MHz,800MHz,1000MHz,用於擴展噪聲帶寬
XO4O options: X040 noise coaxial output: 600 MHZ, 800 MHZ, 1000 MHZ, used to extend the noise bandwidth
