Ọdụ ụgbọ mmiri Waveguide – tebụl ntụnyere nha flange

Mmekọrịta dị n'etiti akụkụ ọdụ ụgbọ mmiri na-efegharị efegharị ***, ** nha flange ***, na ** bandbọchị ugboro *** bụ ahaziri iji hụ na ndakọrịta igwe yana ịrụ ọrụ RF kacha mma. N'okpuru ebe a bụ tebụl ntụnyere dị mfe yana ụkpụrụ ndị bụ isi maka ntuziaka ebili mmiri akụkụ anọ na flange ha jikọtara ya.

### **Etụmatụ isi**
1. ** Nhọpụta Waveguide ***:
Akpọrọ akwụkwọ ntuziaka na "WR" (Waveguide Rectangular) nọmba sochiri ya (dịka ọmụmaatụ, WR-90). Ọnụọgụ ahụ na-adaba akụkụ ** akụkụ mgbidi sara mbara n'ime** n'ime otu narị inch (dịka, WR-90 ≈ 0.90" obosara nke ime).
- Ọmụmaatụ: WR-90 = 0.9" (22.86 mm) obosara ime.

2. ** Ụdị Flange ***:
Flanges na-ahazi njikọ dị n'etiti ndị na-efegharị efegharị. Ụdị nkịtị gụnyere:
- **UG/UPC** (MIL-STD): Flange agha ahaziri ahazi (dịka, UG-387/UPC).
- **CPR** (Azụmahịa): Ụkpụrụ Europe (dịka, CPR-137).
- ** Choke Flanges ***: Maka obere ntapu, ngwa ike dị elu.
- ** Mkpuchi Flanges ***: Dị mfe, ejiri maka mkpuchi oghere.

3. **Ugboro ugboro ***:
Ntuziaka ebili mmiri ọ bụla na-akwado usoro ugboro ole dabere na akụkụ ya.

### ** Akụkụ Flange (Ụdị)**
1. ** Bolt Circle Dayameta (BCD): Dayameta nke okirikiri kpụrụ site na etiti nke arịọnụ bolts.
2. ** oghere oghere ***: Ebe dị n'etiti oghere bolt (dịka ọmụmaatụ, oghere 4 ma ọ bụ 8-hole).
3. ** Oghere Waveguide ***: dakọtara akụkụ dị n'ime nke waveguide.

### ** Mmekọrịta ndị isi**
1. ** Nha Waveguide ↔ Nha Flange **:
- Ntugharị ebili mmiri buru ibu (obere ugboro) na-eji flanges buru ibu (dịka ọmụmaatụ, flange WR-112> flange WR-90).
- Ntuzi ebili mmiri pere mpe (ugboro dị elu) na-eji flange kọmpat (dịka, WR-28, WR-15).

2. ** Ndakọrịta Flange ***:
- Flanges ga-adakọrịrị ** n'ụzọ igwe *** (ndokwa oghere, BCD) na ** eletriki ** (ịga n'ihu impedance).
- Ịgwakọta ụdị flange (dịka, UG-387 na CPR-137) chọrọ nkwụnye.

3. ** Ụkpụrụ site na mpaghara ***:
- ** MIL-STD (UG/UPC): A na-ahụkarị na sistemụ nchekwa US.
- ** IEC/CPR ***: A na-ahụkarị na sistemụ azụmahịa Europe.
