### **Maele a Bohlokwa**
1. **Tlhahiso ea Waveguide**:
Li-Waveguides li ngotsoe ka "WR" (Waveguide Rectangular) e lateloa ke nomoro (mohlala, WR-90). Nomoro e batla e lekana le **tekanyo e ka hare ea lebota le sephara** ka makholo a lisenthimithara (mohlala, WR-90 ≈ 0.90" bophara ba ka hare).
- Mohlala: WR-90 = 0.9" (22.86 mm) bophara ba ka hare.
2. **Mefuta ea Flange**:
Li-flange li tiisa kamano pakeng tsa maqhubu a maqhubu. Mefuta e tloaelehileng e kenyelletsa:
- **UG/UPC** (MIL-STD): Flange e tloaelehileng ea sesole (mohlala, UG-387/UPC).
- ** CPR ** (Khoebo): Litekanyetso tsa Europe (mohlala, CPR-137).
- **Choke Flanges**: Bakeng sa ho lutla ha tlase, lits'ebetso tsa matla a holimo.
- **Koahela Flanges**: E bonolo, e sebelisetsoa ho tiisa vacuum.
3. **Frequency Bands**:
E 'ngoe le e' ngoe ea waveguide e tšehetsa mefuta e itseng ea maqhubu ho latela boholo ba eona.

### **Tafole ea Papiso ea Waveguide-to-Flange**
| **Waveguide** | **Sekhahla sa Maqhubu** | **Mofuta oa Flange** | **Maemo a Flange (Tsela e Tloaelehileng)** | **Likopo ** |
|-------------------------------------------------------------------- | -------------------------------------------------------------------------|
| **WR-90** | 8.2–12.4 GHz (X-band) | UG-387/UPC (MIL) | Bolt Circle: 1.872" (47.5 mm) | Radar, satellite comms. |
| **WR-112** | 7.05–10 GHz (C-band) | UG-595/UPC | Bolt Circle: 2.400" (61.0 mm) | Radar, telecom |
| **WR-62** | 12.4–18 GHz (Ku-band) | UG-385/UPC | Bolt Circle: 1.250 "(31.75 mm) | Satellite, tsamaiso ea sesole |
| **WR-42** | 18–26.5 GHz (K-band) | UG-383/UPC | Bolt Circle: 0.800" (20.3 mm) | Radar ea maqhubu a phahameng |
| **WR-28** | 26.5–40 GHz (Ka-band) | UG-599/UPC | Bolt Circle: 0.600" (15.2 mm) | 5G, radar ea likoloi |
| **WR-15** | 50–75 GHz (V-sehlopha) | UG-387Mini/UPC | Bolt Circle: 0.400" (10.2 mm) | mmWave, lipatlisiso |

### **Litekanyo tsa Flange (Tlhaloso)**
1. **Bolt Circle Diameter (BCD)**: Diameter ea selikalikoe se entsoeng ke litsi tsa liboutu tse ntseng li eketseha.
2. **Sekheo sa Lesoba**: Sebaka pakeng tsa masoba a bolt (mohlala, lipaterone tse 4 kapa tse 8).
3. **Aperture ea Waveguide**: E tsamaisana le litekanyo tse ka hare tsa waveguide.

### **Likamano tsa Bohlokoa**
1. **Boholo ba Waveguide ↔ Flange Size**:
- Li-waveguides tse kholoanyane (likhahla tse tlase) li sebelisa li-flange tse kholoanyane (mohlala, WR-112 flange> WR-90 flange).
- Li-waveguides tse nyane (likhahla tse phahameng) li sebelisa li-compact flanges (mohlala, WR-28, WR-15).
2. **Ho lumellana ha Flange**:
- Flanges e tlameha ho ts'oana le **mechine** (ho tsamaisana le lesoba, BCD) le **ka motlakase** (ho tsoela pele ho sitisa).
- Ho kopanya mefuta ea flange (mohlala, UG-387 le CPR-137) e hloka li-adapter.
3. **Melao ho ya ka Lebatowa**:
- **MIL-STD (UG/UPC)**: E tloaelehileng litsamaisong tsa ts'ireletso tsa US.
- ** IEC / CPR **: E tloaelehileng tsamaisong ea khoebo ea Europe.

- Kamehla netefatsa **metako ea mochini** ho tsoa ho bahlahisi bakeng sa litekanyo tse nepahetseng.
- Li-flange tse sa lumellaneng li baka **ho se tsoele pele ho sitisang **, ho lebisang ho senyeha ha VSWR.
- Bakeng sa litsamaiso tsa vacuum, sebelisa **O-ring e tiisitsoeng e koahelang li-flange **.
