Kwinkalo yezixhobo zemitha yemitha yombane, ii-eriyali ze-RF kunye nee-eriyali ze-microwave zihlala zibhideka, kodwa eneneni kukho umahluko osisiseko. Eli nqaku liqhuba uhlalutyo lobuchwephesha ukusuka kumacala amathathu: inkcazo yebhendi rhoqo, umgaqo woyilo, kunye nenkqubo yokuvelisa, ngakumbi ukudibanisa itekhnoloji ephambili efana neivacuum brazing.

1. Uluhlu lwebhendi rhoqo kunye neempawu zomzimba
I-eriyali ye-RF:
Ibhendi ye-frequency yokusebenza yi-300 kHz - 300 GHz, egubungela usasazo lwamaza aphakathi (535-1605 kHz) ukuya kwimilimitha yamaza (30-300 GHz), kodwa izicelo ezingundoqo zigxininiswe kwi- <6 GHz (ezifana ne-4G LTE, i-WiFi 6). Ubude bobude bubude (isentimitha ukuya kwinqanaba lemitha), ubume ubukhulu becala yi-dipole kunye ne-antenna ye-whip, kwaye uvakalelo lokunyamezela luphantsi (± 1% ubude bobude buyamkelekile).
I-antenna yeMicrowave:
Ngokukodwa i-1 GHz - 300 GHz (i-microwave ukuya kwi-millimeter wave), iibhendi eziqhelekileyo zesicelo ezifana ne-X-band (8-12 GHz) kunye ne-Ka-band (26.5-40 GHz). Iimfuno zobude obufutshane (inqanaba lemilimitha):
✅ Inqanaba le-Submillimeter yokuchaneka kokucubungula (ukunyamezela ≤±0.01λ)
✅ Ulawulo olungqongqo lokurhabaxa komphezulu (< 3μm Ra)
✅ Ilahleko ephantsi yedielectric substrate (ε r ≤2.2, tanδ≤0.001)
2. I-watershed yobugcisa bokuvelisa
Ukusebenza kwee-antenna ze-microwave kuxhomekeke kakhulu kwitekhnoloji yokuvelisa ephezulu:
| Iteknoloji | I-antenna ye-RF | I-Antenna yeMicrowave |
| Itekhnoloji yoqhagamshelwano | Isoldering / ukuqina kweScrew | Vacuum Brazed |
| Ababoneleli abaqhelekileyo | Umzi-mveliso we-Electronics ngokubanzi | Iinkampani zeBrazing ezifana ne-Solar Atmospheres |
| Iimfuno zeWelding | Uqhagamshelwano oluqhubayo | Ukungena kwe-oxygen eyi-Zero, ukulungiswa kwakhona kwesakhiwo sengqolowa |
| Iimetriki eziphambili | Ukuxhathisa <50mΩ | Ukwandiswa komlinganiso wobushushu (ΔCTE<1ppm/℃) |
Ixabiso elingundoqo le-vacuum brazing kwii-eriyali ze-microwave:
1. Uxhulumaniso olungenayo i-oxidation: ukubhobhoza kwindawo ye-10 -5 Torr vacuum ukuphepha i-oxidation ye-Cu / Al alloys kunye nokugcina i-conductivity > 98% IACS
2. Ukupheliswa koxinzelelo lwe-Thermal: ukufudumeza kwemitha ukuya ngaphezulu kolwelo lwesixhobo sokubrawuza (umzekelo, i-BAIsi-4 ingxubevange, i-liquidius 575℃) ukuphelisa ii-microcracks
3. Ulawulo lokuguqulwa: ukuguqulwa ngokubanzi <0.1mm / m ukuqinisekisa ukuhambelana kwesigaba se-millimeter wave
3. Ukuthelekiswa kokusebenza kombane kunye neemeko zesicelo
Iimpawu zemitha:
1.I-eriyali ye-RF: ubukhulu becala imitha ye-omnidirectional, inzuzo ≤10 dBi
2.I-antenna ye-microwave: iyalathiswa kakhulu (ububanzi be-beam 1 ° -10 °), fumana i-15-50 dBi
Usetyenziso oluqhelekileyo:
| I-antenna ye-RF | I-Antenna yeMicrowave |
| Inqaba yerediyo ye-FM | Izigaba zeRadar ye-Radar T / R Components |
| IiSensors ze-IoT | Isondlo sonxibelelwano lwesathelayithi |
| Iithegi zeRFID | 5G mmWave AAU |
4. Uvavanyo lokuqinisekisa umahluko
I-eriyali ye-RF:
- Ugxininiso: Ukuhambelana kokuphazamiseka (VSWR <2.0)
- Indlela: Vector network analyzer frequency tshayela
I-antenna yeMicrowave:
- Ugxininiso: Ipatheni yokusasazeka kwemitha/ukungaguquguquki kwesigaba
- Indlela: Ukuskena kwendawo ekufutshane (ukuchaneka λ/50), uvavanyo lwendawo edibeneyo
Ukuqukumbela: Ii-eriyali zeRF zisisiseko sokuqhagamshelwa kwee-wireless ngokubanzi, ngelixa ii-eriyali ze-microwave zingundoqo we-high-frequency kunye ne-high-precision systems. Uluhlu lwamanzi phakathi kwezi zimbini:
1. Ukunyuka kwamaza okuphindaphinda kukhokelela kubude obufutshane obufutshane, okubangela utshintsho lweparadigm kuyilo.
2. Utshintsho lwenkqubo yokwenziwa kwemveliso - ii-eriyali zemicrowave zixhomekeke kubuchwephesha obuphuma phambili obufana ne-vacuum brazing ukuqinisekisa ukusebenza.
3. Ubunzima bovavanyo bukhula ngokukhawuleza
Izisombululo ze-vacuum brazing ezibonelelwa ziinkampani ezichwephesha zokuqhafaza ezifana ne-Solar Atmospheres ziye zaba sisiqinisekiso esibalulekileyo sokuthembeka kweenkqubo ze-millimeter wave. Njengoko i-6G isanda kwibhendi ye-terahertz frequency, ixabiso lale nkqubo liya kubonakala ngakumbi.
