問題詳情

39. Figure 5 shows a power divider of power ratio PL1/PL2 =1, where PL1 and PL2 are the power delivered to the loads Rei and Riz,respectively. The loads have resistance RiI = 750 and RL2 = 300 , and the characteristic impedance of the transmission line isZ0 = 50 Ω . Find the characteristic impedances Z1 and Z2 of the quarter-wavelength transmission lines

so that theimpedance is matched from the source.


(A) Z1=61.2Ω,Z2 = 122.5Q；
(B)Z1= 122.5Ω, Z2=61.2Ω；
(C)Z1=86.62Ω,Z2=173.2Ω；
(D) Z1= 173.2Ω,Z2 =86.6Ω；
(E) It is impossible to match the loads by using the quarter-wavelength transformers.
