O le sootaga i le va o le **vaveguide port dimensions**, **flange size**, ma **frequency bands** e fa'ata'atiaina ina ia mautinoa le fetaui lelei ma le fa'atinoina o le RF lelei. O lo'o i lalo se laulau fa'atusatusa fa'afaigofieina ma fa'avae autu mo ta'iala fa'ata'ifa'atasi masani ma a latou au fa'atasi.

### **Manatu Autu**
1. **Fa'ailoga Fa'asinoala**:
O ta'iala galu o lo'o fa'ailogaina i le "WR" (Waveguide Rectangular) soso'o ma le numera (fa'ata'ita'iga, WR-90). Ole numera e fa'atatau ile **i totonu o le puipui lautele** i le selau o inisi (fa'ata'ita'iga, WR-90 ≈ 0.90" lautele totonu).
- Faataitaiga: WR-90 = 0.9" (22.86 mm) i totonu lautele.
2. **Ituaiga Flange**:
Flanges fa'ata'atia le feso'ota'iga i va ta'iala galu. O ituaiga masani e aofia ai:
- **UG/UPC** (MIL-STD): Fa'ata'ita'iga fa'afitafita (fa'ata'ita'iga, UG-387/UPC).
- **CPR** (Fa'asalalauga): Tulaga fa'apapalagi (fa'ata'ita'iga, CPR-137).
- **Flanges Choke**: Mo fa'aoga maualalo-leakage, maualuga-malosi.
- **Flanges Ufiufi**: Fa'afaigofie, fa'aoga mo le fa'amau fa'amau.
3. **Fili Fa'atele**:
O ta'iala ta'itasi ta'itasi e lagolagoina se laina fa'apitoa fa'atatau i ona fua.

### **Flange Dimensions (Masa masani)**
1. **Bolt Circle Diameter (BCD)**: Diamita o le li'o na fausia e totonugalemu o fa'amau fa'amau.
2. ** Avanoa o Pu**: Va'a i le va o pu fa'amau (fa'ata'ita'iga, mamanu 4-pu po'o le 8-pu).
3. **Taiala Galu**: E fetaui ma le tele o totonu o le ta'iala galu.

### **Mafutaga Autu**
1. **Tausau Ta'iala ↔ Lapo'a o Flange**:
- O ta'iala fa'aola lapopo'a (vaivai maualalo) e fa'aogaina laugutu lapopo'a (fa'ata'ita'iga, WR-112 flange > WR-90 flange).
- O ta'iala galu laiti (maualuga maualuga) e fa'aogaina lau fe'au fa'apitoa (fa'ata'ita'iga, WR-28, WR-15).
2. **Flange Fegalegaleai**:
- E tatau ona fetaui fa'a'au'au i le **mechanical** (fa'aogaina o pu, BCD) ma le **eletisi** (fa'aauau le fa'alavelave).
- Fa'afefiloi ituaiga flange (fa'ata'ita'iga, UG-387 ma le CPR-137) e mana'omia ni mea fa'apipi'i.
3. **Tulaga Fa'atatau ile Itulagi**:
- **MIL-STD (UG/UPC)**: E masani i faiga tau puipuiga a Amerika.
- **IEC/CPR**: E masani i faiga faapisinisi a Europa.

### **Faamatalaga**
- Fa'amaonia i taimi uma **tusi fa'ainisinia** mai tagata gaosi oloa mo fua sa'o.
- Fa'a'apa'au le fetaui e mafua ai ** fa'alavelave fa'alavelave**, e o'o atu ai i le fa'aleagaina o le VSWR.
- Mo masini gaogao, fa'aoga **O-mama fa'amau fa'amau fa'amaufa'ali'i**.
Ta'u mai ia te a'u pe e te mana'omia se tu'ufa'atasiga ta'iala fa'aalu-flange fa'apitoa!
