2) Achieving stability without worsening too much the noise figure and the gain of the amplifier. Besides the optimal noise figure, the stability of the amplifier is an important aspect in every RF design. Here, the chosen stabilization method is a shunt resistor at the output. Simulation ...
低噪声放大器(low noise amplifier,LNA)是射频接收机前端的重要组成部分。它的主要作用是放大接收到的微弱信号,足够高的增益克服后续各级(如混频器)的噪声,并尽可能少地降低附加噪声的干扰。LNA一般通过传输线直接和天线或天线滤波器相连,由于处于接收机的前端,其抑制噪声的能力直接关系到整个接收系统的性能。因此LNA的...
amplifiers Chinese Name: low noise amplifier English Name: low-noise amplifier definition: a link in amplifier input for a given gain requirement into internal noise as small as possible, and at the output to obtain the maximum possible signal-to-noise ratio and the design of the amplifier. Su...
So far we have largely ignored the presence and effects of electrical noise in the circuits we have been designing. Noise is always present in any electronic or microwave system, however, and can often be the deciding factor in assessing system performance. In this chapter and Chapter 16, we...
