Noise figure to/from noise temperature calculator from Pasternack will produce either noise figure or noise temperature, depending on the input type. When looking at noise figure (NF) calculator output, it measures degradation of the signal-to-noise rat

Noise Figure (NF) is how low-noise amplifiers (LNA) are compared, but the numbers can be misleading. The best LNAs have noise figures of perhaps 0.2 dB, and the differences are in the decimal places. It may seem like the differences are small, but they are significant when compared ...
Noise Power/Noise Temperature 计算方式 回忆一下杂讯指数Noise Figure NF的定义: Noise Figure = SNRin/SNRout 输入讯号噪声比除以输出讯号噪声比,且输入讯号为Ni为kTB T=290K,也就是大家耳熟能响的-174dBm/Hz,所以我们只要能够测量到输出的Noise Power No与增益(Power Gain)就能够算出整个系统的噪声指数Noise...

Desense Noise Figure应该这样测试 Test Card 什么是desensenoise figure? 噪声系数是射频工程师耳熟能详的参数,表征了信号经过一个器件后信噪比的恶化程度。现在所看到的规格书上的噪声系数,基本都是按照IEEE给出的定义: “*The noise factor, at a specified input frequency, is defined as the ratio of 1) ...

为什么会造成desensenoise figure? 实验发现,当存在强干扰信号时,GNSS LNA的噪声系数确实会恶化,为什么会这样呢?难不成强干扰信号改变了晶体管的工作状态? 并不确定强干扰信号能否改变晶体管的工作状态,但可以肯定的是,当干扰信号靠近LNA的工作频段时,会使得LNA进入严重的非线性失真状态,这是否是导致噪声系数恶化的原因...
