Waveguide port - flange size yekuenzanisa tafura

Hukama huri pakati pe **waveguide port dimensions **, ** flange saizi **, uye ** frequency mabhendi ** inomisikidzwa kuti ive nechokwadi chekuenderana nemakanika uye kuita kwakakwana kweRF. Pazasi pane tafura yekuenzanisa yakareruka uye misimboti yakakosha yeakajairwa rectangular waveguides uye anoenderana flanges.

### **Mazano Akakosha**
1. **Waveguide Dhizaini**:
Mawaveguides akanyorwa ne "WR" (Waveguide Rectangular) inoteverwa nenhamba (semuenzaniso, WR-90). Nhamba yacho inoenzana ne **yemukati yakafara-madziro dimension** mumazana emainji (eg, WR-90 ≈ 0.90" mukati mehupamhi).
- Muenzaniso: WR-90 = 0.9" (22.86 mm) upamhi hwemukati.

2. **Flange Types**:
Flanges inomisa hukama pakati pe waveguides. Mhando dzakajairika dzinosanganisira:
- ** UG/UPC** (MIL-STD): Yakamisikidzwa mauto flange (semuenzaniso, UG-387/UPC).
- ** CPR ** (Commercial): European mitemo (semuenzaniso, CPR-137).
- ** Choke Flanges **: Yekudonha-kudonha, yakakwirira-simba maapplication.
- ** Kuvhara Flanges **: Yakareruka, inoshandiswa pakuvharira chisimbiso.

3. **Frequency Bands**:
Imwe neimwe waveguide inotsigira yakatarwa frequency renji zvichienderana nehukuru hwayo.

### **Waveguide-to-Flange Comparison Table**
| **Waveguide** | **Frequency Range** | **Flange Type** | **Flange Dimensions (Yakajairika)** | **Maapplication** |
|-------------------------------------------------------------------|---- ------------------------------------------------------------------------|
| **WR-90** | 8.2–12.4 GHz (X-bhendi) | UG-387/UPC (MIL) | Bolt Circle: 1.872" (47.5 mm) | Radar, satellite comms. |
| **WR-112** | 7.05–10 GHz (C-bhendi) | UG-595/UPC | Bolt Circle: 2.400" (61.0 mm) | Radar, telecom |
| **WR-62** | 12.4–18 GHz (Ku-bhendi) | UG-385/UPC | Bolt Circle: 1.250" (31.75 mm) | Satellite, mauto masisitimu |
| **WR-42** | 18–26.5 GHz (K-bhendi) | UG-383/UPC | Bolt Circle: 0.800" (20.3 mm) | High-frequency radar |
| **WR-28** | 26.5–40 GHz (Ka-band) | UG-599/UPC | Bolt Circle: 0.600" (15.2 mm) | 5G, mota radar |
| **WR-15** | 50–75 GHz (V-bhendi) | UG-387Mini/UPC | Bolt Circle: 0.400" (10.2 mm) | mmWave, tsvakurudzo |

### **Flange Dimensions (Yakajairika)**
1. **Bolt Circle Diameter (BCD)**: Diameter yedenderedzwa yakaumbwa nepakati pemabhoti anokwira.
2. **Hole Spacing**: Chinhambwe pakati pemakomba ebhaudhi (eg, 4-maburi kana 8-maburi mapatani).
3. **Waveguide Aperture**: Inofananidzwa nemukati meiyo waveguide.

### **Makiyi Hukama**
1. **Waveguide Size ↔ Flange Size**:
- Mawaveguide akakura (akadzika mafrequency) anoshandisa maflange makuru (semuenzaniso, WR-112 flange> WR-90 flange).
- Madiki mawaveguides (akakwira ma frequency) anoshandisa compact flanges (semuenzaniso, WR-28, WR-15).

2. **Flange Kuenderana**:
- Flanges inofanirwa kuenderana ** mechaniki ** (gomba alignment, BCD) uye ** zvemagetsi ** (impedance kuenderera).
-Kusanganisa marudzi eflange (semuenzaniso, UG-387 neCPR-137) inoda ma adapter.

3. **Mitemo neNzvimbo**:
- **MIL-STD (UG/UPC)**: Yakajairika muUS kudzivirira masisitimu.
- ** IEC / CPR **: Yakajairika muEuropean kutengeserana masisitimu.

### **Muenzaniso Flange Standards**
| **Flange Type** | **Waveguide Kuenderana ** | **Zvinhu Zvinokosha** |
|--------------------------------------------------------------------------------------------------------------------------------------------------------------------
| **UG-387/UPC** | WR-90, WR-62, WR-42 | 4-gomba, MIL-STD-392, inoshandiswa zvakanyanya. |
| **UG-599/UPC** | WR-28, WR-15 | Compact, yemmWave masisitimu. |
| **CPR-137** | WR-112, WR-90 | European standard, 8-gomba pateni. |
| **Choke Flange** | All | Grooved dhizaini yekudzikisa kudonha. |

### **Zvinyorwa**
-Gara uchisimbisa ** mechanicha kudhirowa ** kubva kune vanogadzira kune chaiwo zviyero.
- Mismatched flanges inokonzeresa ** impedance discontinuities **, zvichiita kuti VSWR iparare.
- Kune vacuum masisitimu, shandisa ** O-mhete yakavharwa yekuvhara maflange **.

Ndizivise kana iwe uchida chaiyo waveguide-flange musanganiswa!
