1. Mitar band iyaka da halaye na jiki
RF eriya:
Ƙungiyar mitar mai aiki shine 300 kHz - 300 GHz, yana rufe watsa shirye-shiryen watsa shirye-shirye na matsakaici (535-1605 kHz) zuwa igiyoyin millimeter (30-300 GHz), amma ainihin aikace-aikacen an tattara su a cikin <6 GHz (kamar 4G LTE, WiFi 6). Tsawon zangon ya fi tsayi (santimita zuwa matakin mita), tsarin ya fi dacewa dipole da eriyar bulala, kuma hankali ga juriya yana da ƙasa (± 1% tsayin igiyar ruwa yana karɓa).
Microwave eriya:
Musamman 1 GHz - 300 GHz (microwave zuwa millimeter wave), nau'ikan mitar aikace-aikacen yau da kullun kamar X-band (8-12 GHz) da Ka-band (26.5-40 GHz). Bukatun gajeriyar tsayin tsayi (matakin millimeter):
✅ Submillimeter matakin sarrafa daidaito (haƙuri ≤± 0.01λ)
✅ Matsakaicin kulawar rashin ƙarfi (<3μm Ra)
✅ Low-asarar dielectric substrate (ε r ≤2.2, tanδ≤0.001)
2. Ruwan ruwa na fasahar kere kere
Ayyukan eriya na microwave ya dogara sosai akan fasahar masana'anta mai tsayi:
| Fasaha | RF Antenna | Antenna Microwave |
| Fasahar haɗi | Soldering/Screw fasting | Vacuum Brazed |
| Na yau da kullun masu kaya | Babban Kamfanin Kayan Lantarki | Kamfanonin Brazing kamar Hasken Rana |
| Bukatun walda | Haɗin haɗin kai | Shigar da iskar oxygen sifili, sake tsara tsarin hatsi |
| Ma'aunin Maɓalli | Kan juriya <50mΩ | Haɗin haɓaka haɓakar thermal (ΔCTE <1ppm/℃) |
Mahimmin ƙimar injin brazing a cikin eriya ta microwave:
1. Haɗin da ba shi da iskar oxygen: brazing a cikin 10 -5 Torr vacuum yanayi don guje wa oxidation na Cu / Al alloys da kuma kula da aiki> 98% IACS
2. Thermal danniya kawar: gradient dumama zuwa sama da liquidus na brazing abu (misali BAISi-4 gami, liquidus 575 ℃) don kawar da microcracks
3. Gudanar da lalata: gaba ɗaya nakasar <0.1mm / m don tabbatar da daidaiton lokacin raƙuman ruwa na millimeter
3. Kwatanta aikin lantarki da yanayin aikace-aikace
Halayen Radiation:
1.Eriyar RF: galibi radiation ta hanyar kai tsaye, samun ≤10 dBi
2.Eriyar Microwave: babban jagora (fidin katako 1°-10°), samun 15-50 dBi
Aikace-aikace na yau da kullun:
| RF Antenna | Antenna Microwave |
| Gidan rediyon FM | Kayan aikin Radar Array T/R |
| Sensors na IoT | Abincin sadarwar tauraron dan adam |
| RFID Tags | 5G mmWave AAU |
4. Gwaji bambance-bambancen tabbatarwa
RF eriya:
- Mayar da hankali: Haɗin kai (VSWR <2.0)
- Hanya: Vector network analyzer share mita
Microwave eriya:
- Mayar da hankali: Tsarin Radiation/daidaicin lokaci
- Hanya: Kusa da sikanin filin (daidaicin λ/50), ƙarancin gwajin filin
Kammalawa: Eriyar RF sune ginshiƙin haɗin haɗin mara waya ta gabaɗaya, yayin da eriya ta microwave sune ainihin tsarin mitoci da madaidaici. Ruwan da ke tsakanin su biyun shi ne:
1. Ƙara yawan mitar yana haifar da taƙaitaccen tsayin raƙuman ruwa, yana haifar da canji a cikin ƙira.
2. Canjin tsari na masana'antu - eriya ta microwave sun dogara da fasaha mai mahimmanci irin su vacuum brazing don tabbatar da aiki.
3. Gwajin gwaji yana girma da yawa
Matsalolin brazing Vacuum wanda ƙwararrun kamfanonin brazing ke bayarwa irin su Solar Atmospheres sun zama babban garanti don amincin tsarin igiyar ruwa na millimeter. Yayin da 6G ke faɗaɗa zuwa rukunin mitar terahertz, ƙimar wannan tsari zai zama sananne.
Don ƙarin koyo game da eriya, da fatan za a ziyarci:
