1. ** Ilana Waveguide ***:
Waveguides jẹ aami pẹlu "WR" (Waveguide Rectangular) atẹle nipa nọmba kan (fun apẹẹrẹ, WR-90). Nọmba naa ṣe isunmọ ** iwọn odi gbooro ti inu ** ni awọn ọgọọgọrun inch kan (fun apẹẹrẹ, WR-90 ≈ 0.90” iwọn inu).
- Apeere: WR-90 = 0.9" (22.86 mm) akojọpọ iwọn.
2. ** Awọn oriṣi Flange ***:
Flanges standardize awọn asopọ laarin waveguides. Awọn oriṣi ti o wọpọ pẹlu:
- ** UG/UPC *** (MIL-STD): Apejuwe flange ologun (fun apẹẹrẹ, UG-387/UPC).
- ** CPR *** (Ti owo): Awọn ajohunše Ilu Yuroopu (fun apẹẹrẹ, CPR-137).
- ** Awọn flanges choke ***: Fun jijo kekere, awọn ohun elo agbara giga.
- ** Awọn Flanges Ideri ***: Rọrun, ti a lo fun lilẹ igbale.
