Radio telescope feed source filtering and feeding network electromagnetic transmitting characteristics measurement
Publish Time:2025-01-08
The measurement of SPP filtering feed network and superconducting filtering feed network electric performance,including the transmitting parameters of insertion losses S11 and return losses S21 of the filters. The data index: the mutual coupling between the filtering feed network ports≤-20dB, the depth of notch:-40dB, the insertion loss within passband:≤0.15dB, the standing wave within passband:≤1.2, the minimal out-of-band suppression:-40dB.
