Impedance matching in microwave
WitrynaIt is shown that a bi-directional waveguide launcher can be used advantageously for reducing the reflection coefficient mismatch of an input impedance of an applicator. In a simple bi-directional waveguide launcher, the magnetron is placed in the waveguide and generates a nominal field distribution … Witryna22 maj 2024 · The results are shown in Figure 7.5.1. It is interesting to derive the characteristic impedance at the center of the taper. At the center of the taper, z = 0, ϕ(0, A) = 0 and Equation (7.5.10) becomes. lnZ0(0) = 1 2ln(ZSZL), that is, Z0(0) = √ZSZL. which is the geometric mean of the source and load resistances.
