【文章內(nèi)容簡(jiǎn)介】 How much gain (or loss) you get is usually more important than how much the signal has been phase shifted. 20 Sparameters Sparameters depend upon the work and the characteristic impedances of the source and load used to measure it, and the frequency measured at. . if the work is changed, the Sparameters change. if the frequency is changed, the Sparameters change. if the load impedance is changed, the Sparameters change. if the source impedance is changed, the Sparameters change. What do Sparameters depend on? 21 Sparameters What do Sparameters depend on? Sparameters depend upon the work and the characteristic impedances of the source and load used to measure it, and the frequency measured at. . if the work is changed, the Sparameters change. if the frequency is changed, the Sparameters change. if the load impedance is changed, the Sparameters change. if the source impedance is changed, the Sparameters change. In th Si9000e Sparameters are quoted with source and load impedances of 50 Ohms 22 Sparameters What do Sparameters depend on? Sparameters depend upon the work and the characteristic impedances of the source and load used to measure it, and the frequency measured at. . if the work is changed, the Sparameters change. if the frequency is changed, the Sparameters change. if the load impedance is changed, the Sparameters change. if the source impedance is changed, the Sparameters change. 23 Sparameters A little math… This is the matrix algebraic representation of 2 port Sparameters: Some matrices are symmetrical. A symmetrical matrix has symmetry about the leading diagonal. 24 Sparameters A little math… This is the matrix algebraic representation of 2 port Sparameters: Some matrices are symmetrical. A symmetrical matrix has symmetry about the leading diagonal. In the case of a 2port work, that means that S21 = S12 and interchanging the input and output ports does not change the transmission properties. 25 Sparameters A litt
