Munyaya yemidziyo yemwaranzi yemagetsi, maantenna eRF nemaantenna e microwave anowanzo vhiringidzwa, asi pane misiyano mikuru. Chinyorwa chino chinoita ongororo yehunyanzvi kubva pazvikamu zvitatu: tsananguro yebhendi yema frequency, musimboti wekugadzira, uye maitiro ekugadzira, kunyanya kusanganisa matekinoroji akakosha akadai sekuputira vacuum.
RF MISOFurnace yeVacuum Brazing
1. Rudzi rwebhendi remafrequencies uye hunhu hwemuviri
Kanyanga yeRF:
Band yekushanda iri 300 kHz - 300 GHz, ichifukidza kuburitswa kwemafungu epakati (535-1605 kHz) kusvika ku millimeter wave (30-300 GHz), asi mashandisirwo epakati akanyanya kuverengerwa mu < 6 GHz (senge 4G LTE, WiFi 6). Wavelength yakareba (centimeter kusvika padanho remita), chimiro chacho chinonyanya kuve dipole ne whip antenna, uye kunzwisiswa kwekushivirira kwakaderera (± 1% wavelength inogamuchirwa).
Antena ye microwave:
Zvikuru 1 GHz - 300 GHz (microwave kusvika millimeter wave), mabhendi efrequency akajairika ekushandisa akadai seX-band (8-12 GHz) uye Ka-band (26.5-40 GHz). Zvinodiwa zvewavelength pfupi (millimeter level):
✅ Kunyatsogadzirisa nhanho ye submillimeter (kushivirira ≤±0.01λ)
✅ Kudzora kuomarara kwenzvimbo (< 3μm Ra)
✅ Substrate ye dielectric ine kurasikirwa kwakaderera (ε r ≤2.2, tanδ≤0.001)
2. Kubudirira kwetekinoroji yekugadzira zvinhu
Kushanda kwema antenna e microwave kunoenderana zvikuru netekinoroji yekugadzira yepamusoro-soro:
| Tekinoroji | Kanyanga dzeRF | Kanyanga ye microwave |
| Tekinoroji yekubatanidza | Kusunga/Kusunga Screw | Yakaputirwa nesimbi yeVacuum |
| Vatengesi Vakajairika | Fekitori Yemagetsi Yese | Makambani ekugadzira mabhurazi akaita seSolar Atmospheres |
| Zvinodiwa pakushongedza | Kubatana kwekufambisa | Kupinda kweokisijeni pasina, kurongwazve kwechimiro chezviyo |
| Zviyero Zvikuru | Kusadzivirirwa <50mΩ | Kuenzanisa kwekuwedzera kwemafuta (ΔCTE<1ppm/℃) |
Kukosha kukuru kwekushandisa vacuum brazing mu microwave antennas:
1. Kubatana kusina oxidation: brazing munzvimbo ine vacuum ye 10 -5 Torr kudzivirira oxidation yeCu/Al alloys uye kuchengetedza conductivity >98% IACS
2. Kubvisa kushushikana kwekupisa: kupisa kwegradient kusvika pamusoro pemvura yesimbi (semuenzaniso BAISi-4 alloy, liquidus 575℃) kubvisa mitswe midiki.
3. Kudzora kuchinja: kuchinja kwese <0.1mm/m kuve nechokwadi chekuti millimeter wave phase inowirirana
3. Kuenzanisa mashandiro emagetsi uye mamiriro ekushandisa
Hunhu hwemwaranzi:
1.RF antenna: inonyanya kushandisa mwaranzi ye-omnidirectional, kuwedzera ≤10 dBi
2.Antena ye microwave: inotungamira zvakananga (hupamhi hwedanda 1°-10°), kuwedzera 15-50 dBi
Maitiro akajairika:
| Kanyanga dzeRF | Kanyanga ye microwave |
| Nhare yeredhiyo yeFM | Zvikamu zveRadar yePhased Array T/R |
| MaSensor eIoT | Chidimbu chekutaurirana nesatellite |
| Matagi eRFID | 5G mmWave AAU |
4. Musiyano wekusimbisa bvunzo
Kanyanga yeRF:
- Kutarisa: Kufananidza Impedance (VSWR < 2.0)
- Nzira: Vector network analyzer frequency sweep
Antena ye microwave:
- Kutarisa: Radiation pattern/phase consistency
- Nzira: Kuskena kwemunda pedyo (kururama kwe λ/50), bvunzo yemunda mudiki
Mhedziso: Maantenna eRF ndiwo musimboti wekubatanidza waya zvisina waya, ukuwo maantenna e microwave ari musimboti wemasystem ane mafrequency akawanda uye akanyatsojeka. Chikamu chiri pakati pezviviri izvi ndeichi:
1. Kuwedzera kwehuwandu hwemafungu kunotungamira kupfupiso yewavelength, zvichikonzera shanduko yemaonero mukugadzirwa
2. Kuchinja kwemaitiro ekugadzira - ma antenna e microwave anoshandisa matekinoroji epamusoro akadai se vacuum brazing kuti ave nechokwadi chekuti anoshanda zvakanaka
3. Kuoma kwebvunzo kunowedzera zvakanyanya
Mhinduro dzekushandisa vacuum brazing dzinopihwa nemakambani ehunyanzvi ekugadzira mabrazing akadai seSolar Atmospheres dzave vimbiso huru yekuvimbika kwema millimeter wave systems. Sezvo 6G ichikura kusvika ku terahertz frequency band, kukosha kwemaitiro aya kuchawedzera kuoneka.
Kuti udzidze zvakawanda nezve antenna, ndapota shanyira:
