Summary
| Ku-band composite asymmetric E-plane corrugated band-pass filter. Similar filter was proposed for SkyBridge space program. In spite of small dimensions (4.18''x1.82''x1.19'') the filter provides relatively high multipaction breakdown 3000W (0.080'' min voltage gap) and more rejection of spurious spectrum than 15'' long conventional cascade of iris filter of at least 15 poles and corrugated filter of at least 15 corrugations. |
