Unformatted text preview: EE 4002 RF Circuit Design Transmission Lines Part 4 Sourced and Loaded Transmission Lines • So far we have been looking at TL with a load attached. We observed that a launced wave into the TL is reflected at the load unless there is perfect matching: o L Z Z = • Now let’s attach a source to the line. We must consider impedance mismatch between the source and the line. in V Sourced and Loaded Transmission Lines 2 ( ) j l in o in o in o Z Z d l e Z Z β-- Γ = Γ = = = Γ + G o s G o Z Z Z Z- Γ = + Moving down TL from right to left, RTW reflection becomes: LTW reflected from load reflects again at source-line mismatch: … moving down TL from left to right, LTW reflects at load: 2 j l out s e β- Γ = Γ G S G Z Z Z Z- Γ = + The Transmission Coefficient • A similar term used to describe reflection is the transmission coefficient. 2 1 in in in in Z T Z Z = + Γ =- Input transmission coefficient at the beginning of the line: 2 1 L L Z T Z Z = + Γ =- Load transmission coefficient at the end of line: •...
