Itheyibhile yokuthelekisa ubungakanani be-Waveguide port

Ubudlelwane phakathi kobukhulu bezibuko ze-**waveguide**, ubungakanani be-**flange**, kunye ne-**frequency bands** bumiselwe ukuqinisekisa ukuhambelana koomatshini kunye nokusebenza kwe-RF okuphezulu. Apha ngezantsi kukho itheyibhile yokuthelekisa elula kunye nemigaqo ephambili ye-waveguide eqhelekileyo ye-rectangular kunye ne-flanges ezinxulumene nazo.

### **Iingcamango eziphambili**
1. **Ukubekwa kweWaveguide**:
Ii-Waveguides ziphawulwe ngo-"WR" (i-Waveguide Rectangular) zilandelwa linani (umz., WR-90). Inani liqikelelwa kubukhulu bodonga olubanzi lwangaphakathi** kwikhulu le-intshi (umz., WR-90 ≈ 0.90" ububanzi bangaphakathi).
- Umzekelo: WR-90 = 0.9" (22.86 mm) ububanzi bangaphakathi.

2. **Iintlobo zeFlange**:
Iiflanges zenza unxibelelwano phakathi kwezikhokelo zamaza lube semgangathweni. Iindidi eziqhelekileyo ziquka:
- ** UG / UPC ** (MIL-STD): I-flange yomkhosi esemgangathweni (umzekelo, i-UG-387 / UPC).
- **CPR** (Ezorhwebo): Imigangatho yaseYurophu (umz., CPR-137).
- **Iiflanges zeChoke**: Zenzelwe ukusetyenziswa kwamandla aphezulu, okuvuza kancinci.
- **Iiflanges zeSigqubuthelo**: Zilula ngakumbi, zisetyenziselwa ukuvala i-vacuum.

3. **Iibhendi zeFrequency**:
I-waveguide nganye ixhasa uluhlu oluthile lwefrikhwensi ngokusekelwe kubukhulu bayo.

### **Itheyibhile yokuthelekisa isikhokelo samaza ukuya kwi-Flange**
| **Isikhokelo samaza** | **Uluhlu lweeFleji** | **Uhlobo lweFlange** | **Ubukhulu beFlange (Eqhelekileyo)** | **Izicelo** |
|---------------|- ...
| **WR-90** | 8.2–12.4 GHz (X-band) | UG-387/UPC (MIL) | Isangqa seBolt: 1.872" (47.5 mm) | Iradar, ii-satellite comms. |
| **WR-112** | 7.05–10 GHz (ibhendi ye-C) | UG-595/UPC | Isangqa seBolt: 2.400" (61.0 mm) | Iradar, itelecom |
| **WR-62** | 12.4–18 GHz (Ku-band) | UG-385/UPC | Isangqa seBolt: 1.250" (31.75 mm) | Isathelayithi, iinkqubo zomkhosi |
| **WR-42** | 18–26.5 GHz (i-K-band) | UG-383/UPC | Isangqa seBolt: 0.800" (20.3 mm) | Iradar ephindaphindayo |
| **WR-28** | 26.5–40 GHz (Ka-band) | UG-599/UPC | Isangqa seBolt: 0.600" (15.2 mm) | 5G, iradar yeemoto |
| **WR-15** | 50–75 GHz (V-band) | UG-387Mini/UPC | Isangqa seBolt: 0.400" (10.2 mm) | mmWave, uphando |

### **Ubukhulu beFlange (Eqhelekileyo)**
1. **Ububanzi besangqa seBolt (BCD)**: Ububanzi besangqa esenziwe ziindawo eziphakathi zeebholiti ezifakelwayo.
2. **Isithuba seMingxunya**: Umgama phakathi kwemingxuma yebholiti (umz., iipateni ezinemingxuma emi-4 okanye ezi-8).
3. **Imbobo ye-Waveguide**: Ihambelana nobukhulu bangaphakathi be-waveguide.

### **Ubudlelwane obuPhambili**
1. **Ubungakanani beWaveguide ↔ Ubungakanani beFlange**:
- Ii-waveguides ezinkulu (ii-frequency ezisezantsi) zisebenzisa ii-flanges ezinkulu (umz., i-WR-112 flange > i-WR-90 flange).
- Ii-waveguides ezincinci (ii-frequency eziphezulu) zisebenzisa ii-compact flanges (umz., WR-28, WR-15).

2. **Ukuhambelana kweFlange**:
- Iiflange kufuneka zihambelane **ngoomatshini** (ulungelelwaniso lwemingxunya, iBCD) kunye **ngombane** (ukuqhubeka kwe-impedance).
- Ukuxuba iintlobo zeflange (umz., UG-387 kunye ne-CPR-137) kufuna iiadaptha.

3. **Imigangatho ngokweSithili**:
- **MIL-STD (UG/UPC)**: Ixhaphakile kwiinkqubo zokhuselo zaseMelika.
- **IEC/CPR**: Ixhaphakile kwiinkqubo zorhwebo zaseYurophu.

### **Imigangatho yeFlange yoMzekelo**
| **Uhlobo lweFlange** | **Ukuhambelana kweWaveguide** | **Iimpawu eziphambili** |
|------------------|- ...
| **UG-387/UPC** | WR-90, WR-62, WR-42 | Imingxunya emi-4, iMIL-STD-392, isetyenziswa kakhulu. |
| **UG-599/UPC** | WR-28, WR-15 | Incinci, yeenkqubo ze-mmWave. |
| **CPR-137** | WR-112, WR-90 | Ipatheni esemgangathweni yaseYurophu, enemingxunya esi-8. |
| **Iflange yokuChoka** | Konke | Uyilo olunemiqolo ukuze kuncitshiswe ukuvuza. |

### **Amanqaku**
- Soloko uqinisekisa imizobo ye-**mechanical** evela kubavelisi ukuze ufumane ubungakanani obuchanekileyo.
- Iiflange ezingangqinelaniyo zibangela ukungabikho kwe-impedance**, nto leyo ekhokelela ekuwohlokeni kwe-VSWR.
- Kwiinkqubo zokucoca umoya, sebenzisa iiflanges ze-**O-ring ezitywiniweyo**.
