Q. |
A circular cavity resonator has a wave number of 151, radius of 2.74 cm, and surface resistance of 0.0184Ω. If the cavity is filled with a dielectric of 2.01, then unloaded Q due to conductor loss is: |
A. | 25490 |
B. | 21460 |
C. | 29390 |
D. | none of the mentioned |
Answer» C. 29390 | |
Explanation: unloaded q of a circular resonator due to conductor loss is given by ka/2rs. is the intrinsic impedance of the medium. substituting the given values in the equation for loaded q, value is 29390. |
