Microwave Communication - Engineering

Q1:

Assertion (A): A half wavelength line can be used as a 1 : 1 transformer. Reason (R): The input impedance of a half wavelength line is equal to load impedance.

A Both A and R are correct and R is correct explanation of A

B Both A and R are correct but R is not correct explanation of A

C A is correct but R is wrong

D A is wrong but R is correct

ANS:A - Both A and R are correct and R is correct explanation of A

Since a half wavelength line has an input impedance equal to load impedance, the impedance transformation ratio is 1:1.
