1.	For maximum power transfer, a lossless transmission line 50 ohm is to be matched to a resistive load impedance of 100 ohm. The characteristic impedance of the wavelength/4 transformer is(a) 70.7(b) 50(c) 100(d) InfinityI got this question in quiz.Question is from Advanced and Tricky Questions in section Advanced and Tricky Questions of Electromagnetic Theory
Answer» Right ANSWER is (a) 70.7 The best EXPLANATION: For MAXIMUM power transfer, Zin = Z0^2/ZL. On substituting for the GIVEN values, we get the CHARACTERISTIC impedance as 70.7 ohm.
