采用噪声计算中的阻抗场法计算了瑞利波放大器的噪声系数。半导体中噪声与声波的耦合是由一个正模公式得到的。结果表明,应获得相对较低的噪声数字,并且捕获现象可能是噪声激发的主要来源。
The noise figure of a Rayleigh wave amplifier is calculated using the impedance field method of noise calculation. The coupling of noise in the semiconductor to the acoustic wave is obtained from a normal mode formula. The results indicate that relatively low noise figures should be obtainable, and that trapping phenomena can be the major source of noise excitation.
