Hauv kev lag luam hluav taws xob hluav taws xob hluav taws xob, RF kav hlau txais xov thiab microwave kav hlau txais xov feem ntau tsis meej pem, tab sis qhov tseeb muaj qhov sib txawv. Kab lus no ua cov kws tshaj lij kev tshuaj xyuas los ntawm peb qhov loj me: qhov ntau zaus band txhais, tsim qauv, thiab cov txheej txheem tsim khoom, tshwj xeeb tshaj yog sib txuas cov thev naus laus zis tseem ceeb xws linqus brazing.
RF MISONqus Brazing Rauv
1. Ntau zaus band ntau thiab cov yam ntxwv ntawm lub cev
RF kav hlau txais xov:
Kev khiav hauj lwm zaus band yog 300 kHz - 300 GHz, npog nruab nrab nthwv dej tshaj tawm (535-1605 kHz) mus rau millimeter yoj (30-300 GHz), tab sis cov ntawv thov tseem ceeb yog nyob hauv <6 GHz (xws li 4G LTE, WiFi 6). Lub wavelength ntev (centimeter mus rau 'meter'), tus qauv yog feem ntau dipole thiab nplawm kav hlau txais xov, thiab rhiab heev rau kam rau ua yog tsawg (± 1% wavelength yog txais).
Microwave kav hlau txais xov:
Tshwj xeeb tshaj yog 1 GHz - 300 GHz (microwave rau millimeter nthwv dej), cov ntawv thov zaus bands xws li X-band (8-12 GHz) thiab Ka-band (26.5-40 GHz). Luv wavelength (millimeter theem) yuav tsum muaj:
✅ Submillimeter qib ua qhov raug (qhov siab ≤ ± 0.01λ)
✅ Kev tswj kom nruj roughness (< 3μm Ra)
✅ Tsawg-poob dielectric substrate (ε r ≤2.2, tanδ≤0.001)
2. Lub watershed ntawm manufacturing technology
Kev ua tau zoo ntawm microwave kav hlau txais xov yog nyob ntawm high-end manufacturing technology:
| Technology | RF Kav hlau txais xov | Microwave Kav hlau txais xov |
| Kev sib txuas tshuab | Soldering/Screw fastening | Nqus Brazed |
| Yam khoom | General Electronics Factory | Lub tuam txhab Brazing zoo li Hnub Ci Atmospheres |
| Vuam xav tau | Kev sib txuas ua ke | Zero oxygen nkag mus, grain qauv reorganization |
| Kev ntsuas qhov tseem ceeb | Ua haujlwm tsis kam <50mΩ | Thermal expansion coefficient (ΔCTE <1ppm / ℃) |
Tus nqi tseem ceeb ntawm lub tshuab nqus tsev brazing hauv microwave antennas:
1. Oxidation-free kev twb kev txuas: brazing nyob rau hauv 10 -5 Torr lub tshuab nqus tsev ib puag ncig kom tsis txhob oxidation ntawm Cu / Al alloys thiab tswj conductivity> 98% IACS
2. Kev tshem tawm kev ntxhov siab: gradient cua sov mus rau saum cov kua dej ntawm cov khoom siv brazing (xws li BAISi-4 alloy, liquidus 575 ℃) kom tshem tawm cov microcracks
3. Deformation tswj: zuag qhia tag nrho deformation <0.1mm/m los xyuas kom meej millimeter yoj theem sib xws
3. Kev sib piv ntawm hluav taws xob kev ua tau zoo thiab kev siv cov xwm txheej
Radiation yam ntxwv:
1.RF kav hlau txais xov: feem ntau omnidirectional hluav taws xob, nce ≤10 dBi
2.Microwave kav hlau txais xov: muaj kev taw qhia siab (nqaj dav 1 ° -10 °), nce 15-50 dBi
Tej kev siv:
| RF Kav hlau txais xov | Microwave Kav hlau txais xov |
| FM xov tooj cua ntauwd | Phased Array Radar T / R Cheebtsam |
| IoT Sensors | Satellite kev sib txuas lus pub |
| RFID Tags | 5G mmWave AAU |
4. Kev kuaj xyuas qhov sib txawv
RF kav hlau txais xov:
- Ua kom pom tseeb: Impedance matching (VSWR < 2.0)
- Txoj kev: Vector network analyzer zaus cheb
Microwave kav hlau txais xov:
- Ua kom pom tseeb: Radiation qauv / theem sib xws
- Txoj kev: Nyob ze ntawm qhov chaw soj ntsuam (qhov tseeb λ/50), kev sim ntsuas qhov ntsuas
Xaus: RF kav hlau txais xov yog lub hauv paus ntawm kev sib txuas wireless dav dav, thaum lub kav hlau txais xov microwave yog qhov tseem ceeb ntawm cov tshuab hluav taws xob siab thiab siab. Cov dej ntws nruab nrab ntawm ob yog:
1. Qhov kev nce hauv zaus ua rau luv luv wavelength, ua rau muaj kev hloov pauv hauv kev tsim
2. Kev tsim cov txheej txheem hloov pauv - microwave kav hlau txais xov tso siab rau cov thev naus laus zis xws li lub tshuab nqus tsev brazing kom ntseeg tau tias kev ua tau zoo
3. Kev ntsuam xyuas qhov nyuaj zuj zus tuaj
Nqus brazing kev daws teeb meem muab los ntawm cov tuam txhab kev lag luam brazing xws li Hnub Ci Atmospheres tau dhau los ua qhov tseem ceeb lav rau kev ntseeg siab ntawm millimeter yoj tshuab. Raws li 6G nthuav dav mus rau terahertz zaus band, tus nqi ntawm cov txheej txheem no yuav ua kom pom tseeb dua.
