WebA transmission line with termination applied at the load end. A CMOS IC is assumed in this figure. At the load end, the characteristic impedance needs to match the load component’s input impedance, which is derived in the above image. There is a reflection coefficient defined at the interface between the load component and the transmission line. WebA reflection coefficient is defined as the ratio of reflected wave to incident wave at a reference plane. This value varies from -1 (for a shorted load) to +1 (for an open load), and …

Webtransfer from stage to stage. In RF-power transistors the input impedance is of low value, decreasing as the power increases, or as the chip size becomes larger. This impedance must be matched either to a generator — of generally 50 ohms internal impedance — or to a preceding stage. Impedance transformation ratios of 10 or even 20 are not rare.

Web29 Jul 2024 · Note also that the Mismatch Loss is not an index of efficiency: with matched load, we got the highest power on the load (50W) but efficiency was at 50% (100W produced, 50W used on the load).
