Emkhakheni wemishini yemisebe kagesi, izimpondo ze-RF nezimpondo ze-microwave zivame ukudideka, kodwa empeleni kunomehluko obalulekile. Lesi sihloko senza ukuhlaziya okuphrofeshinali kusuka kubukhulu obuthathu: incazelo yebhendi yemvamisa, umgomo wokuklama, kanye nenqubo yokukhiqiza, ikakhulukazi ukuhlanganisa ubuchwepheshe obubalulekile obufana no.i-vacuum brazing.
RF MISOVacuum Brazing Furnace
1. Ibanga lebhendi yefrikhwensi nezici zomzimba
I-antenna ye-RF:
Ibhendi yefrikhwensi yokusebenza ingu-300 kHz - 300 GHz, emboza ukusakaza kwegagasi okumaphakathi (535-1605 kHz) kuya kumagagasi amamilimitha (30-300 GHz), kodwa izinhlelo zokusebenza eziyinhloko zigxile ku-< 6 GHz (njenge-4G LTE, WiFi 6). Ubude begagasi bude (isentimitha ukuya ezingeni lemitha), isakhiwo ngokuyinhloko siyi-dipole kanye ne-antenna ye-whip, futhi ukuzwela ekubekezeleni kuphansi (± 1% ubude beza kuyamukeleka).
I-antenna ye-Microwave:
Ngokukhethekile i-1 GHz - 300 GHz (igagasi le-microwave ukuya ku-millimeter), amabhendi emvamisa yohlelo lokusebenza ajwayelekile afana ne-X-band (8-12 GHz) ne-Ka-band (26.5-40 GHz). Izimfuneko zamaza amaza amafushane (izinga lemilimitha):
✅ Ukunemba kokucubungula kwezinga le-submillimeter (ukubekezelelana ≤±0.01λ)
✅ Ukulawulwa okuqinile kokuma okungaphezulu (< 3μm Ra)
✅ I-dielectric substrate yokulahlekelwa okuphansi (ε r ≤2.2, tanδ≤0.001)
2. Isizinda samanzi sobuchwepheshe bokukhiqiza
Ukusebenza kwama-antenna e-microwave kuncike kakhulu kubuchwepheshe bokukhiqiza obusezingeni eliphezulu:
| Ubuchwepheshe | I-RF Antenna | I-Antenna ye-Microwave |
| Ubuchwepheshe bokuxhumana | Soldering/Screw fasting | Vacuum Brazed |
| Abahlinzeki abajwayelekile | I-General Electronics Factory | Izinkampani ze-Brazing ezifana ne-Solar Atmospheres |
| Izidingo zokushisela | Ukuxhumana okusebenzayo | Ukungena kwe-oxygen engu-Zero, ukuhlelwa kabusha kwesakhiwo sokusanhlamvu |
| Amamethrikhi angukhiye | Ukumelana nokumelana <50mΩ | Ukufanisa i-coefficient yokwandisa okushisayo (ΔCTE<1ppm/℃) |
Inani eliyinhloko le-vacuum brazing kuma-antenna ama-microwave:
1. Uxhumano olungenayo i-oxidation: ukubrasa endaweni yevacuum engu-10 -5 Torr ukugwema i-oxidation yama-alloys e-Cu/Al kanye nokugcina ukuhanjiswa > 98% IACS
2. Ukuqedwa kokucindezeleka okushisayo: ukushisisa kwe-gradient kuze kube ngaphezu kwe-liquid yezinto zokubrawuza (isb. I-BAIsi-4 alloy, liquidus 575℃) ukuze kuqedwe ama-microcracks
3. Ukulawulwa kokuguqulwa: ukuwohloka okuphelele <0.1mm/m ukuze kuqinisekiswe ukufana kwesigaba se-millimeter wave
3. Ukuqhathaniswa kokusebenza kukagesi kanye nezimo zohlelo lokusebenza
Izici zokukhishwa kwemisebe:
1.I-antenna ye-RF: ikakhulukazi imisebe ye-omnidirectional, zuza ≤10 dBi
2.I-antenna ye-Microwave: iqonde kakhulu (ububanzi be-beam 1 ° -10 °), ithola i-15-50 dBi
Izinhlelo zokusebenza ezijwayelekile:
| I-RF Antenna | I-Antenna ye-Microwave |
| Umbhoshongo womsakazo we-FM | Izingxenye ze-T/R ze-Radar ye-Phased Array |
| Izinzwa ze-IoT | Isiphakeli sokuxhumana ngesathelayithi |
| RFID Tags | 5G mmWave AAU |
4. Hlola umehluko wokuqinisekisa
I-antenna ye-RF:
- Ukugxila: Ukuqhathanisa kokuphazamiseka (VSWR <2.0)
- Indlela: I-Vector network analyzer frequency sweep
I-antenna ye-Microwave:
- Ukugxila: Iphethini yokukhishwa kwemisebe/ukungaguquguquki kwesigaba
- Indlela: Ukuskena kwenkambu eseduze (ukunemba λ/50), ukuhlolwa kwenkambu ehlangene
Isiphetho: Ama-antenna e-RF ayisisekelo sokuxhuma okungenantambo okuvamile, kuyilapho izimpondo ze-microwave ziwumongo wesistimu yefrikhwensi ephezulu kanye nokunemba okuphezulu. I-watershed phakathi kwalokhu kokubili yile:
1. Ukwenyuka kwemvamisa kuholela kubude beza obufushanisiwe, okubangela ukushintsha kwepharadigm ekwakhiweni
2. Inguquko yenqubo yokukhiqiza - izinti ze-microwave zithembele kubuchwepheshe obusezingeni eliphezulu obufana ne-vacuum brazing ukuqinisekisa ukusebenza
3. Ubunkimbinkimbi bokuhlolwa bukhula ngokuqhubekayo
Izixazululo ze-vacuum brazing ezihlinzekwa izinkampani ezichwepheshile zokubethela ezifana ne-Solar Atmospheres seziphenduke isiqinisekiso esibalulekile sokuthembeka kwezinhlelo zamagagasi amamilimitha. Njengoba i-6G inweba kubhendi yefrikhwensi ye-terahertz, inani lale nqubo lizogqama kakhulu.
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
