Chiteshi cheWaveguide - tafura yekufananidza saizi yeflange

Hukama huripo pakati pe **waveguide port dimensions**, **flange sizes**, uye **frequency bands** hwakajairwa kuti huve nechokwadi chekuti mashandiro emakanika anoenderana uye mashandiro eRF akanakisa. Pazasi pane tafura yekufananidza iri nyore uye misimboti mikuru yema waveguides akafanana e rectangular uye ma flanges akabatana nawo.

### **Pfungwa Dzinokosha**
1. **Kusarudzwa kweWaveguide**:
Mawaveguide akanyorwa ne "WR" (Waveguide Rectangular) achiteverwa nenhamba (semuenzaniso, WR-90). Nhamba iyi inofungidzira **mukati memadziro akafara** muzvikamu zana zve inchi (semuenzaniso, WR-90 ≈ 0.90" mukati mehupamhi).
- Muenzaniso: WR-90 = 0.9" (22.86 mm) upamhi hwemukati.

2. **Mhando dzeFlange**:
Maflanges anoita kuti kubatana pakati pemawaveguides kuve kwakaenzana. Mhando dzakajairika dzinosanganisira:
- ** UG/UPC** (MIL-STD): Yakamisikidzwa mauto flange (semuenzaniso, UG-387/UPC).
- **CPR** (Zvekutengeserana): Mitemo yeEurope (semuenzaniso, CPR-137).
- **Maflange eChoke**: Kune mashandisirwo asingadonhedze mvura yakawanda uye ane simba guru.
- **Mafurangi Ekuvhara**: Ari nyore, anoshandiswa pakuvhara vacuum.

3. **Mabhendi Emafrequency**:
Giravhizheni yega yega inotsigira huwandu hwema frequency hwakatarwa zvichienderana nehukuru hwayo.

### **Tafura Yekuenzanisa Yemafungu-Kuenda-KuFlange**
| **Guide yeWave** | **Range yeFlange** | **Rudzi rweFlange** | **Zviyero zveFlange (Zvakajairika)** | **Mashandisirwo** |
|---------------|- ...
| **WR-90** | 8.2–12.4 GHz (X-band) | UG-387/UPC (MIL) | Denderedzwa reBolt: 1.872" (47.5 mm) | Radar, kutaurirana kwesatellite. |
| **WR-112** | 7.05–10 GHz (C-band) | UG-595/UPC | Denderedzwa reBolt: 2.400" (61.0 mm) | Radar, telecom |
| **WR-62** | 12.4–18 GHz (Ku-band) | UG-385/UPC | Denderedzwa reBolt: 1.250" (31.75 mm) | Satellite, masisitimu emauto |
| **WR-42** | 18–26.5 GHz (K-band) | UG-383/UPC | Denderedzwa reBolt: 0.800" (20.3 mm) | Radar ine mafrequency akakwira |
| **WR-28** | 26.5–40 GHz (Ka-band) | UG-599/UPC | Bolt Denderedzwa: 0.600" (15.2 mm) | 5G, radar yemotokari |
| **WR-15** | 50–75 GHz (V-band) | UG-387Mini/UPC | Denderedzwa reBolt: 0.400" (10.2 mm) | mmWave, tsvakurudzo |

### **Zviyero zveFlange (Zvakajairika)**
1. **Bholt Circle Diameter (BCD)**: Dhayamita yedenderedzwa inoumbwa nepakati pemabhaudhi anosungirirwa.
2. **Kureba kweMaburi**: Kureba pakati pemaburi emabhaudhi (semuenzaniso, mapatani ane maburi mana kana maburi masere).
3. **Nzvimbo yeWaveguide**: Inoenderana nehukuru hwemukati hwewaveguide.

### **Hukama Hunokosha**
1. **Saizi yeWaveguide ↔ Saizi yeFlange**:
- Mawaveguides makuru (mafrequency akaderera) anoshandisa maflanges makuru (semuenzaniso, WR-112 flange > WR-90 flange).
- Mawaveguides madiki (mafrequency akakwirira) anoshandisa ma compact flanges (semuenzaniso, WR-28, WR-15).

2. **Kuenderana kweFlange**:
- Maflanges anofanira kuenderana ne **mechanically** (kurongeka kwemaburi, BCD) uye **electrically** (kuenderera mberi kwe impedance).
- Kusanganisa mhando dzeflange (semuenzaniso, UG-387 neCPR-137) kunoda maadapter.

3. **Zviyero neDunhu**:
- **MIL-STD (UG/UPC)**: Yakajairika muhurongwa hwekudzivirira hweUS.
- **IEC/CPR**: Zvinowanikwa mumasystem ekutengeserana ekuEurope.

### **Mienzaniso yeFlange Standards**
| **Rudzi rweFlange** | **Kuenderana kweWaveguide** | **Zvinhu Zvikuru** |
|------------------|- ...
| **UG-387/UPC** | WR-90, WR-62, WR-42 | ine maburi mana, MIL-STD-392, inoshandiswa zvakanyanya. |
| **UG-599/UPC** | WR-28, WR-15 | Yakabatana, yemasisitimu emmWave. |
| **CPR-137** | WR-112, WR-90 | Muyero weEurope, patani ine maburi masere. |
| **Choke Flange** | Zvese | Dhizaini ine grooved yekuderedza kubuda kwemvura. |

### **Zvinyorwa**
- Gara uchiongorora **madhirowa emakanika** kubva kuvagadziri kuti uone saizi chaiyo.
- Maflange asina kuenzana anokonzera **kusagadzikana kweimpedance**, zvichikonzera kuora kweVSWR.
- Kune masisitimu evacuum, shandisai **O-ring sealed cover flanges**.

Ndiudzei kana muchida musanganiswa chaiwo we waveguide-flange!
