Make sure all circuit elements and schematic are clearly defined.ĥ) Evaluate the value of reactance X and length L, such that Zin would come out to be 50 ohms. Matching impedance adalah penyepadanan pada saluran yang dilakukan agar impedansi input saluran transmisi ZIN ZO, sehingga terjadi transfer daya maksimum. Zin Γin 4) Clearly show a matching network for a load of Z=25-j50 Ω to a 50 Ω system at 300 MHz (a) using only lumped elements, (b) using only open-stubs, (c) using a transmission line (any kind) and a quarter-wave transformer. For instance smithplot (MNOBJ, CircuitIndex, Z0, ) plots the impedance transformation for the selected matching network circuit at the characteristic impedance, Z0 on a smith chart. d) What is the VSWR on the transmission line in (c), if possible?ģ) Using Smith Chart only, evaluate the input impedance and reflection coefficient at 300 MHz given that ZL = 50 + j 150 Ω. smithplot(,Name,Value) plots the impedance transformation from the source to load on a Smith chart with additional properties given by Name, Value pair. If this is not possible, state the reasons.
Calculate the impedance and line length of that transmission line. Use the Smith chart to find the following quantities for the transmission line. c) using ONLY a single transmission line to match it at a single frequency. Zin 2) Clearly show a matching network for the load ZL = 40 – j10 Ω to a 50 Ω system at 1 GHz, a) using ANY transmission lines, b) using a lumped constant circuit element (L or C) AND a shunt transmission line. Problem 2.50 Use the Smith chart to determine the input impedance Zin of the two-line configuration shown in Fig. 1) Using Smith Chart only, evaluate the input impedance Zin at 500 MHz as shown in Figure.
