Cov khoom no yog ib qho kev ua tau zoo, voltage-tswj kuj sib txawv attenuator tsim los ua hauj lwm tshaj ib tug tsis tshua muaj bandwidth ntawm DC mus rau 8GHz, muab ib tug nruam attenuation ntau yam txog li 30dB. Nws tus qauv SMA RF interfaces ua kom muaj kev sib txuas yooj yim thiab txhim khu kev qha nrog ntau lub tshuab ntsuas thiab cov khoom siv hluav taws xob, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tswj cov teeb liab meej hauv RF thiab microwave systems niaj hnub.
Yam ntxwv:
1. Ultra-wideband tsim: Npog ntau zaus ntawm DC mus rau 8GHz, zoo kawg nkaus ua tau raws li cov kev xav tau ntawm ntau pawg thiab kev siv dav dav xws li 5G, kev sib txuas lus satellite, thiab kev tiv thaiv hluav taws xob. Ib qho kev tivthaiv tuaj yeem ua tiav qhov kev xav tau ntawm lub tshuab broadband.
2. Precise voltage control: Nruam attenuation ntawm 0 mus rau 30dB yog tiav los ntawm ib tug analog voltage interface. Cov khoom lag luam nthuav tawm cov yam ntxwv zoo linear tswj, kom ntseeg tau tias muaj kev sib raug zoo ntawm kev sib raug zoo ntawm attenuation thiab tswj voltage kom yooj yim kev sib koom ua ke thiab kev ua haujlwm.
3. Kev ua tau zoo ntawm RF: Ua kom pom qhov qis qis qis thiab qhov zoo tshaj plaws voltage sawv yoj piv rau tag nrho cov kev khiav hauj lwm zaus band thiab attenuation ntau. Nws tiaj tus attenuation nkhaus kom lub teeb liab waveform kev ncaj ncees yam tsis muaj distortion nyob rau hauv txawv attenuation xeev, guaranteeing system teeb liab kev ncaj ncees.
4. Kev sib koom ua ke siab thiab kev ntseeg siab: Siv cov cuab yeej siv siab tshaj MMIC (Monolithic Microwave Integrated Circuit) cov cuab yeej, cov khoom lag luam muaj cov qauv tsim kom muaj zog thiab ruaj khov, muab qhov kub thiab txias zoo sib xws, ua rau nws haum rau cov cheeb tsam hnyav nrog kev ntseeg siab heev.
Daim ntawv thov:
1. Automated test khoom: Siv nyob rau hauv kev sim tshuab rau kev sib txuas lus wireless thiab radar modules rau cov calibration meej, dynamic range expansion, thiab receiver rhiab heev kuaj.
2. Kev sib txuas lus systems: Siv rau hauv 5G hauv paus chaw nres tsheb, taw tes-to-point microwave txuas, thiab satellite kev sib txuas lus cov cuab yeej rau kev tswj tsis siv neeg nce loops kom ruaj khov theem teeb liab thiab tiv thaiv cov receiver overload.
3. Hluav taws xob ua tsov rog thiab radar systems: Siv rau kev simulation teeb liab, hluav taws xob countermeasures, thiab radar mem tes shaping, enabling sai attenuation hloov rau lub teeb liab deception los yog kev tiv thaiv ntawm rhiab receiver raws.
4. Laboratory R & D: Muab engineers nrog ib tug saj zawg zog, programmable attenuation tov thaum lub sij hawm tsim qauv thiab validation theem, ua rau kev ntsuam xyuas ntawm Circuit Court thiab system dynamic kev ua tau zoo.
Qualwave Inc. muab broadband, siab dynamic ntau yamvoltage tswj attenuatorsnrog zaus mus txog 90GHz. Tsab ntawv xov xwm no qhia txog DC mus rau 8GHz voltage tswj attenuator nrog rau qhov attenuation ntau ntawm 0 txog 30dB.
