Pazida zamagetsi zamagetsi, tinyanga ta RF ndi tinyanga ta microwave nthawi zambiri zimasokonezeka, koma pali kusiyana kwakukulu. Nkhaniyi ikuwunikira akatswiri kuchokera pamiyeso itatu: kutanthauzira kwa band pafupipafupi, kapangidwe kake, ndi kupanga, makamaka kuphatikiza matekinoloje ofunikira monga.vacuum brazing.
RF MISOVacuum Brazing Ng'anjo
1. Mafupipafupi gulu osiyanasiyana ndi maonekedwe thupi
RF mlongoti:
Gulu la ma frequency ogwiritsira ntchito ndi 300 kHz - 300 GHz, lomwe limaphimba mafunde apakati (535-1605 kHz) mpaka ma millimeter wave (30-300 GHz), koma mapulogalamu oyambira amakhazikika mu <6 GHz (monga 4G LTE, WiFi 6). Kutalika kwa mafunde ndi kotalika (masentimita mpaka mulingo wa mita), kapangidwe kake kamakhala ka dipole ndi mlongoti wa chikwapu, ndipo kukhudzika kwa kulolerana ndikotsika (± 1% kutalika kwa mafunde ndikovomerezeka).
Antenna ya Microwave:
Makamaka 1 GHz - 300 GHz (microwave to millimeter wave), ma frequency ogwiritsira ntchito monga X-band (8-12 GHz) ndi Ka-band (26.5-40 GHz). Zofunikira zazifupi (millimeter level):
✅ Submillimeter level processing kulondola (kulolera ≤±0.01λ)
✅ Kuwongolera mwamphamvu pamwamba (<3μm Ra)
✅ Gawo la dielectric lotayika pang'ono (ε r ≤2.2, tanδ≤0.001)
2. Madzi opangira ukadaulo wopanga
Kuchita kwa ma antenna a microwave kumadalira kwambiri ukadaulo wapamwamba wopanga:
| Zamakono | RF Antenna | Antenna ya Microwave |
| Tekinoloje yolumikizira | Soldering / screw fasting | Vacuum Brazed |
| Ma Suppliers Odziwika | General Electronics Factory | Makampani a Brazing ngati Solar Atmospheres |
| Zofunika kuwotcherera | Conductive mgwirizano | Kulowa kwa okosijeni wa Zero, kukonzanso kamangidwe kambewu |
| Ma Metrics Ofunika | Kukaniza <50mΩ | Kufananitsa kofanana ndi kukulitsa kwamafuta (ΔCTE<1ppm/℃) |
Phindu lalikulu la vacuum brazing mu tinyanga ta microwave:
1. Kulumikizana kopanda makutidwe ndi okosijeni: kuwotcha mu 10 -5 Torr vacuum chilengedwe kuti mupewe oxidation ya Cu/Al alloys ndikusunga ma conductivity> 98% IACS
2. Kuchotsa kupsinjika kwamafuta: Kutentha kwa gradient mpaka pamwamba pamadzi amadzimadzi (monga BAISi-4 aloyi, liquidus 575 ℃) kuchotsa ma microcracks
3. Kuwongolera kosinthika: kusinthika kwathunthu <0.1mm/m kuonetsetsa kusasinthika kwa gawo la millimeter wave
3. Kuyerekeza kwa ntchito zamagetsi ndi zochitika zogwiritsira ntchito
Mawonekedwe a radiation:
1.RF mlongoti: makamaka omnidirectional radiation, phindu ≤10 dBi
2.Mlongoti wa Microwave: wolunjika kwambiri (m'lifupi mwake 1 ° -10 °), pezani 15-50 dBi
Mapulogalamu odziwika:
| RF Antenna | Antenna ya Microwave |
| FM wailesi nsanja | Zigawo za Phased Array Radar T / R |
| Masensa a IoT | Satellite kulankhulana chakudya |
| RFID Tags | 5G mmWave AAU |
4. Kusiyana kotsimikizira koyesa
RF mlongoti:
- Kuyikira Kwambiri: Kufananiza kwa Impedans (VSWR <2.0)
- Njira: Vector network analyzer kusesa pafupipafupi
Antenna ya Microwave:
- Kuyikira Kwambiri: Ma radiation / gawo kusasinthasintha
- Njira: Kujambulira pafupi ndi munda (kulondola λ/50), kuyesa kwa compact field
Kutsiliza: Tinyanga za RF ndiye mwala wapangodya wamalumikizidwe opanda zingwe wamba, pomwe tinyanga ta microwave ndiye maziko a makina othamanga kwambiri komanso olondola kwambiri. Mtsinje wamadzi pakati pa ziwirizi ndi:
1. Kuwonjezeka kwafupipafupi kumabweretsa kufupikitsa kwa kutalika kwa mawonekedwe, zomwe zimayambitsa kusintha kwa paradigm
2. Kusintha kwa njira zopangira - tinyanga ta microwave timadalira matekinoloje apamwamba kwambiri monga vacuum brazing kuti zitsimikizire kugwira ntchito.
3. Kuvuta kwa mayeso kumakula kwambiri
Mayankho a vacuum brazing omwe amaperekedwa ndi makampani opangira magetsi ngati Solar Atmospheres akhala chitsimikizo chofunikira pakudalirika kwa machitidwe a mafunde a millimeter. Pamene 6G ikufutukula ku gulu lafupipafupi la terahertz, phindu la njirayi lidzakhala lodziwika kwambiri.
Kuti mudziwe zambiri za antennas, chonde pitani:
