Waveguide Manual Phase Shifters yog cov khoom siv tsis siv neeg siv rau RF thiab microwave teeb liab ua haujlwm uas tuaj yeem kho cov theem ntawm lub teeb liab. Lawv yog cov tseem ceeb nyob rau hauv daim ntawv thov uas yuav tsum tau muaj meej tswj ntawm lub teeb liab theem.
1. Phase Adjustment: Lub waveguide phau ntawv qhia theem shifter yog siv los kho cov theem ntawm cov teeb liab kom ua tiav cov theem tswj tau meej. Qhov no yog qhov tseem ceeb heev rau theem kev sib piv thiab theem kev hloov kho.
2. Theem Nyiaj Them Nqi: Lawv siv los them nyiaj rau theem kev ua yuam kev hauv lub kaw lus thiab xyuas kom meej tias theem ntawm lub teeb liab ntawm txoj kev sib txawv zoo ib yam, yog li kev txhim kho kev ua haujlwm ntawm lub system.
3. Beamforming: Los ntawm kev kho cov theem ntawm txhua chav kav hlau txais xov nyob rau hauv lub kav hlau txais xov array, waveguide phau ntawv theem shifter tuaj yeem ua tiav beamforming thiab beam scanning.
4. Phase Match: Nyob rau hauv ntau lub tshuab, waveguide phau ntawv qhia theem hloov pauv tau siv los xyuas kom meej tias cov theem ntawm txhua qhov channel zoo ib yam, yog li ua tiav theem sib txuam.
Lub waveguide phau ntawv qhia theem hloov pauv muaj ntau yam kev siv hauv kev sib txuas lus hauv hluav taws xob, thiab ib qho ntawm nws lub luag haujlwm tseem ceeb yog theem calibration.
1. Hauv kev sib txuas lus, cov theem hloov pauv tuaj yeem siv los synchronize cov teeb liab los ntawm cov teeb liab sib txawv lossis txoj hauv kev los xyuas kom meej tias lawv tuaj txog ntawm qhov kawg tau txais nrog rau theem raug. Los ntawm kev kho cov theem ntawm cov teeb liab tawm tswv yim, cov theem shifter ua tau raws li qhov yuav tsum tau muaj ntawm theem calibration, yog li kev txhim kho kev ua haujlwm thiab kev ruaj ntseg.
2. Phase shifters yog dav siv nyob rau hauv kev hloov kho thiab demodulation cov txheej txheem los kho cov theem ntawm cov khoom thauj, thiaj li ua tiav cov teeb liab demodulation thiab paub txog cov kev hloov pauv sib txawv (xws li PSK, QAM, thiab lwm yam).
3. Nyob rau hauv cov nqe lus ntawm zaus synthesis, theem shifters yuav siv tau los kho cov theem ntawm cov teeb liab ntawm ntau zaus, yog li ua tiav lub hom phiaj ntawm zaus synthesis.
4. Kev sib txuas lus digital: Bidi.
Qhov no ua lub luag haujlwm tseem ceeb hauv thaj chaw xws li kev sib txuas lus wireless thiab radar systems.
Qualwavemuab Waveguide Phau Ntawv Qhia Phase Shifters los ntawm 8.2 txog 12.4GHz. Kev hloov kho theem yog mus txog 360 ° / GHz.
