### **Echiche Ndị Dị Mkpa**
1. **Nhọpụta Onye Nduzi Ebugharị**:
A na-eji akara "WR" (Nkume Waveguide) akara ndị na-eduzi Waveguide, wee soro ya nọmba (dịka ọmụmaatụ, WR-90). Nọmba ahụ na-eme ka akụkụ mgbidi sara mbara nke dị n'ime **n'ime otu narị inch (dịka ọmụmaatụ, obosara ime WR-90 ≈ 0.90").
- Ihe atụ: WR-90 = 0.9" (22.86 mm) obosara ime.

2. **Ụdị Flange**:
Flanges na-eme ka njikọ dị n'etiti ndị na-eduzi ebili mmiri dị mma. Ụdị ndị a na-ahụkarị gụnyere:
- **UG/UPC** (MIL-STD): Flange agha ahaziri ahazi (dịka, UG-387/UPC).
- **CPR** (Azụmahịa): Ụkpụrụ ndị Europe (dịka ọmụmaatụ, CPR-137).
- **Ọkụ Choke Flanges**: Maka ojiji na-anaghị agbapụta nke ọma, ma na-enye ike dị elu.
- **Mkpuchi Flanges**: Dị mfe, a na-eji ya eme ihe mkpuchi ikuku.

3. **Ugboro ugboro**:
Onye nduzi ebili mmiri ọ bụla na-akwado oke ugboro ole a kapịrị ọnụ dabere na nha ya.
