- Commercial GaAs pHEMT transistors, Agilent ATF-35143, were used in this 2-stage amplifier. At a physical temperature 15K the amplifier achieves noise temperature between 3.2K and 3.8K over 1600MHz to 1740MHz band. 该放大器采用了Agilent 公司ATF-35143 假晶高电子迁移率场效应管(pHEMT),为两级级联结构,频率范围1600MHz~1740MHz。
- Reduced noise: Being a simpler device, a direct drive mechanism has fewer parts which could vibrate, and the overall noise emission of the system is usually lower. 分别就是指效率提高,降低噪音,更长的使用寿命,低转速就可产生高扭矩。
- Where possible “quiet” plant shall be selected in order to minimize the overall noise burden to be sustained and to maximize the allowable plant under any particular CNP. 尽可能选用“安静”的设备,以将建筑噪音许可证规定的总体噪音负荷最小化,并将容许设备最大化。
- The noise temperature is in the most favourable case given by the temperature of the receiver. 理想的噪声温度即是接收机的温度。
- Overall noise of this system is pelow10.000pwop in the 2500km hypotheti-cal reference circuit. 2500pwop of the total noise is allococated to the thetical equipment and 7500pwop to the repeatered line which Sufficiently Satisfies the CCITT Recommendation. 在2500Km的模拟参考电路上的总杂音小于10,000pwop,其中分配终端设备的杂音为2500pwop,线路增音设备为7500pwop,这完全符合CCITT的建议。
