Xidhiidhka u dhexeeya ** cabbirrada dekeda waveguide ***, ** cabbirrada flange ***, iyo ** xirmooyinka soo noqnoqda *** waa la jaangooyay si loo hubiyo ku habboonaanta farsamada iyo waxqabadka RF ee ugu habboon. Hoos waxaa ku yaal miiska isbarbardhigga oo la fududeeyey iyo mabaadi'da muhiimka ah ee hagaha mawjadaha leyliga ah ee caadiga ah iyo garabyada la xiriira.

### ** Fikradaha Muhiimka ah ***
1. ** Magacaabista Waveguide ***:
Waveguide waxaa lagu calaamadeeyay "WR" (Waveguide Rectangular) oo ay ku xigto lambar (tusaale, WR-90). Lambarku waxa uu ku qiyaasaa ** cabbirka gidaarka ballaadhan ee gudaha** boqollaal inji (tusaale, WR-90 ≈ 0.90" ballac gudaha ah).
- Tusaale: WR-90 = 0.9" (22.86 mm) ballac gudaha ah.
2. ** Noocyada Flange ***:
Flanges ayaa halbeega xidhiidhka ka dhexeeya waveguides. Noocyada caadiga ah waxaa ka mid ah:
- **UG/UPC** (MIL-STD): Garab ciidan oo heersare ah (tusaale, UG-387/UPC).
- **CPR** (Ganacsi): Heerarka Yurub (tusaale, CPR-137).
- ** Flanges Choke ***: Si aad u hooseeya, codsiyada awoodda sare leh.
- ** Dabool Flanges ***: Ka fudud, oo loo isticmaalo xidhidhiyaha faakuumka.
3. **Kooxaha Joogtada ah**:
Waveguide kastaa wuxuu taageeraa kala duwanaansho soo noqnoqda oo gaar ah oo ku salaysan cabbirkeeda.

### **Miiska Isbarbardhigga Wave-to-Flange**
| **Hagaha Wave** | ** Xadka Soo noqnoqda** | ** Nooca Flange** | ** Cabbirrada Flange (Caadi)** | **Codsiyada** |
|-------------------
| ** WR-90** | 8.2–12.4 GHz (X-band) | UG-387/UPC (MIL) | Goobabada Bolt: 1.872" (47.5 mm) | Radar, comms satellite. |
| ** WR-112** | 7.05–10 GHz (C-band) | UG-595/UPC | Goobabada Bolt: 2.400" (61.0 mm) | Radar, telecom |
| **WR-62** | 12.4–18 GHz (Ku-band) | UG-385/UPC | Goobabada Bolt: 1.250" (31.75 mm) | Satellite, nidaamyada militariga |
| **WR-42** | 18–26.5 GHz (K-band) | UG-383/UPC | Goobabada Bolt: 0.800" (20.3 mm) | Raadaarka-sare ee soo noqnoqda |
| **WR-28** | 26.5–40 GHz (Ka-band) | UG-599/UPC | Goobabada Bolt: 0.600" (15.2 mm) | 5G, radar baabuur |

### ** Cabirka Flange (Caadi)**
1. **Bolt Circle Diameter (BCD)**: Dhexroor goobada oo ay sameysteen xarumaha boolal-kordhinta.
2. **Doodfogeynta**: Fogaanshaha u dhexeeya godadka boodhka ah (tusaale, 4-dalool ama qaababka 8-god).
3. ** Aperture Waveguide ***: Wuxuu ku habboon yahay cabbirrada gudaha ee hagaha.

### **Xiriirka Muhiimka ah**
1. ** Xajmiga Waveguide ↔ Cabbirka Flange*:
- Mawjadaha waaweyn ee mawjadaha (soo noqnoqoshada hoose) waxay isticmaalaan garbaha waaweyn (tusaale, flange WR-112> Flange WR-90).
-Hagaha mawjadaha yaryar (soo noqnoqoshada sare) waxay adeegsadaan garabyo is haysta (tusaale, WR-28, WR-15).
2. ** Waafaqsanaanta Flange ***:
- Flanges waa in ay u dhigmaan ** farsamo ahaan *** (isku xidhka godka, BCD) iyo ** koronto ahaan *** (sii wadida carqaladaynta).
- Isku darka noocyada flange (tusaale, UG-387 oo wata CPR-137) waxay u baahan tahay adapters.
3. **Heerka Gobolka**:
- ** MIL-STD (UG/UPC): Caadi ahaan nidaamyada difaaca Mareykanka.
- ** IEC/CPR ***: Caadi ahaan nidaamyada ganacsiga Yurub.

### **Xusuusin**
- Had iyo jeer ka xaqiiji ** sawirada makaanikada *** ka soosaarayaasha cabbirada saxda ah.
- Garaafka aan is-bar-bar-dhigi karin waxay sababaan ** joojinta joojinta**, taasoo horseedaysa hoos u dhaca VSWR.
- Nidaamyada faakuumka, isticmaal **O-ring garbaha daboolan oo daboolan ***.
