Question

A generator is connected to a transmission line system that is shown below. The system consists of two transmission lines, each with a characteristic impedance of 75 [2], connected to a load impedance of 75 [2]. These two lines are then fed by a single main feed line having a characteristic impedance 75 [2], which is fed by the generator (not shown). It is desired to have a match on the main feeding line at the design frequency fo. (Note that you do not need to know what the actual design frequency is, since all dimensions will be normalized by the wavelength.) This is done in two different ways, as shown below. The first is by using a quarter-wave transformer, and the second is by using a single-stub matcher. In each case, assume that Zo- 75 [2], and that the wavelength is the same on all transmission lines. Tasks 1) Design the quarter-wave transformer that will give a match at the design frequency. Give all relevant dimensions (in terms of a wavelength). 2) Design the single-stub matcher that will give a match at the design frequency. Give all 3) For the quarter-wave transformer design, generate a plot of the SWR on the main feeding 4) For the single-stub matcher design, generate a plot of the SWR on the main feeding line relevant dimensions (in terms of a wavelength) line vs. the normalized frequency fI fo, where fo is the design frequency vs. the normalized frequency f/ o, where fo is the design frequency 5) Calculate the percent bandwidths of each system, defined as 100 where fi and 2 are the lower and upper frequencies for which SWR-2.0. Comment on how the bandwidth compares between the two matching methods.
