Cov Kab Ncua Kev Tswj Xyuas Digital RF Xov Tooj Cua Zaus Microwave Millimeter Wave
Cov Kab Ncua Kev Tswj Xyuas Digital yog ib qho khoom siv microwave uas tuaj yeem tswj lub sijhawm ncua sijhawm los ntawm cov teeb liab digital. Nws lub hauv paus ntsiab lus yog kho lub network hloov sab hauv lossis hloov qhov ntev ntawm txoj kev teeb liab, yog li tswj qhov kev ncua sijhawm ntawm lub teeb liab. Piv rau cov kab ncua sijhawm ib txwm muaj thiab cov cables ncua sijhawm ruaj khov, cov kab ncua kev tswj hwm digital muaj cov txiaj ntsig zoo.
Cov kab qeeb qeeb uas tswj tau los ntawm digital muaj cov txiaj ntsig zoo li nram no:
1. Kev ntsuas siab: Cov kab qeeb qeeb uas tswj los ntawm digital tuaj yeem ua tiav cov kauj ruam qeeb qeeb los ntawm kev tswj digital, feem ntau ncav cuag qhov kev daws teeb meem ntawm 1 ps lossis txawm tias 0.5ps.
2. Broadband: Cov kab digital qeeb feem ntau ua haujlwm los ntawm DC mus rau ntau kaum ntawm GHz (piv txwv li, 40GHz) thiab tswj qhov qeeb qeeb zoo thoob plaws ntau zaus.
3. Ntau yam dynamic loj: Cov kauj ruam digital qeeb kab tuaj yeem ua tiav qhov ntau yam hloov kho tau los ntawm 0ps mus rau ntau nanoseconds (piv txwv li, 10ns lossis siab dua), npog ntau yam kev siv.
4. Kev tswj tau programmable: Cov kab qeeb qeeb uas tswj tau digitally tuaj yeem programmed los ntawm cov qauv digital interfaces xws li SPI, I2C, lossis kev tswj parallel, muab kev ywj pheej siab rau kev koom ua ke ntawm lub kaw lus.
Cov kab qeeb qeeb uas tswj los ntawm digital feem ntau yog siv rau hauv cov teb xws li kev sim microwave, radar, kev sib txuas lus, thiab kev sib txuas lus satellite.
Piv txwv li, siv cov kab digital qeeb rau kev sim, cov kab digital qeeb no siv tau rau: Simulate cov teeb liab qeeb - los ntsuas lub sijhawm thiab lub zog ntawm lub cuab yeej uas raug sim (DUT). Calibrating lub kaw lus sim - los sib phim theem thiab lub sijhawm, kom ntseeg tau tias qhov ntsuas raug thiab sib xws. Tsis tas li ntawd, hauv phased array radar thiab 5G kev sib txuas lus, cov kab digital qeeb siv rau: Beamforming thiab beam steering - los tswj kev coj ntawm lub antenna array beam.
Qualwavemuab cov kab qeeb qeeb uas tswj los ntawm digital broadband thiab high dynamic range nrog cov zaus txog li 18 GHz. Cov kauj ruam qeeb qeeb tuaj yeem qis li 1.25ps, thiab tag nrho cov kev ncua qeeb tuaj yeem ncav cuag 25ns lossis ntau dua. Peb cov kab qeeb qeeb uas tswj los ntawm digital muaj cov khoom zoo thiab kev ntseeg siab.
