The circuit topology affects input and output impedance. Generally, the resource impedance is matched towards the input impedance mainly because that can optimize the power transfer with the source on the device. If your source impedance is very low, then a standard base or popular gate circuit topology might be https://low-noiseamplifier11111.bloggazza.com/36834746/5-tips-about-coaxial-switch-you-can-use-today
