At higher microwave frequencies, roughly 8 GHz and higher, cavity resonators are preferred to LC resonators. Which rationale below is the best explanation for this fact? Cavity resonators have much higher quality factor (Q) than L-C resonators. Cavity resonators are much smaller than L-C resonators. Cavity resonators cost less than L-C resonators. Cavity resonators are more "trendy" than L-C resonators.
