Ma Tee Osakondera, 0.1 ~ 26.5GHz, SMA

Chogulitsachi ndi cha DC bias tee chogwira ntchito bwino kwambiri, chomwe chimagwira ntchito kuyambira 0.1 mpaka 26.5GHz. Chili ndi zolumikizira zolimba za SMA ndipo chapangidwa kuti chiziyesa kwambiri ma microwave RF circuit test komanso kuphatikiza makina. Chimaphatikiza bwino komanso mopanda vuto ma signal a RF ndi mphamvu ya DC bias, zomwe zimapangitsa kuti chikhale chofunikira kwambiri m'ma laboratories amakono, ndege, mauthenga, ndi zida zamagetsi zodzitetezera.

Makhalidwe:

1. Kugwiritsa ntchito ma frequency ambiri: Ubwino wake waukulu ndi ma frequency band otakata kwambiri, omwe amaphimba kuyambira 100MHz mpaka 26.5GHz, omwe amathandizira pafupifupi ma frequency band onse omwe angapezeke ndi ma SMA interfaces, kuphatikiza mapulogalamu apamwamba monga 5G, kulumikizana kwa satellite, ndi kuyesa kwa ma millimeter-wave.
2. Kutayika kochepa kwambiri kwa ma insertion: Njira ya RF imawonetsa kutayika kochepa kwambiri kwa ma insertion pa frequency band yonse, kuonetsetsa kuti ma signal akuyenda bwino komanso kuti akuyenda bwino, pomwe akuchepetsa kukhudzidwa kwa chipangizo chomwe chikuyesedwa kapena makina.
3. Kudzipatula kwabwino kwambiri: Pogwiritsa ntchito ma capacitor oletsa kugwira ntchito bwino komanso ma RF choke mkati, zimapangitsa kuti pakhale kudzipatula kwakukulu pakati pa doko la RF ndi doko la DC. Izi zimaletsa kutulutsa kwa chizindikiro cha RF kulowa mu DC supply ndikupewa phokoso kuchokera ku DC supply kusokoneza chizindikiro cha RF, ndikuwonetsetsa kuti muyeso ndi wolondola komanso kukhazikika kwa dongosolo.
4. Kugwira ntchito mwamphamvu komanso kukhazikika: Doko la DC limatha kugwira ntchito mpaka 700mA ya mphamvu yopitilira ndipo lili ndi mphamvu yoteteza mphamvu yopitirira muyeso. Lili m'bokosi lachitsulo, limapereka chitetezo chabwino, mphamvu ya makina, komanso kutentha, zomwe zimapangitsa kuti lizigwira ntchito bwino kwa nthawi yayitali ngakhale m'malo ovuta.
5. Zolumikizira za SMA Zolondola: Madoko onse a RF amagwiritsa ntchito zolumikizira za SMA-Female zokhazikika, zomwe zimapereka kulumikizana kodalirika, VSWR yochepa, kubwerezabwereza bwino, komanso koyenera kulumikizana pafupipafupi komanso mayeso olondola kwambiri.

Mapulogalamu:

1. Kuyesa kwa chipangizo chogwira ntchito: Kumagwiritsidwa ntchito kwambiri poyesa ma transistors a microwave ndi ma amplifiers monga GaAs FETs, HEMTs, pHEMTs, ndi MMICs, kupereka mphamvu yeniyeni komanso yoyera ya bias ku zipata zawo ndi drains, pomwe kumalola kuyeza kwa S-parameter pa wafer.
2. Kusankha module ya Amplifier: Kumagwira ntchito ngati netiweki yodziyimira payokha popanga ndi kuphatikiza ma module monga ma amplifiers opanda phokoso lotsika, ma amplifiers amphamvu, ndi ma amplifiers a driver, kupangitsa kuti kapangidwe ka ma circuit kakhale kosavuta komanso kusunga malo a PCB.
3. Kulankhulana kwa kuwala & madalaivala a laser: Amagwiritsidwa ntchito popereka DC bias kwa ma modulators othamanga kwambiri, madalaivala a laser diode, ndi zina zotero, pamene akutumiza zizindikiro za RF modulation za liwiro lalikulu.
4. Makina oyesera okha (ATE): Chifukwa cha kuchuluka kwa bandwidth yake komanso kudalirika kwake, ndi yoyenera kugwiritsidwa ntchito mumakina a ATE kuti ayesere okha komanso mozama ma module ovuta a microwave monga ma module a T/R ndi ma converter okwera/otsika.
5. Kafukufuku & maphunziro: Chida chabwino kwambiri choyesera ma microwave circuit ndi machitidwe m'mayunivesite ndi mabungwe ofufuza, kuthandiza ophunzira kumvetsetsa mfundo za kapangidwe ka zizindikiro za RF ndi DC zomwe zimagwiritsidwa ntchito nthawi imodzi.

Qualwave Inc. imaperekama t-shirts okonderandi zolumikizira zosiyanasiyana mu mitundu ya Standard / High RF Power / Cryogenic kuti zikwaniritse zosowa zosiyanasiyana za makasitomala. Ma frequency amatha kufikira 16kHz mpaka 67GHz m'lifupi mwake. Nkhaniyi ikubweretsa tee ya SMA bias ya 0.1 ~ 26.5GHz.
