Ama-Digital Controlled Phase Shifters

Ama-Digital Controled Phase Shifters amadivayisi alungisa isigaba sezimpawu ze-microwave ngokulawula kwedijithali. Isimiso esiyisisekelo ukusebenzisa ubuchwepheshe bokucubungula izimpawu zedijithali ukuze kuhlolwe futhi kulinganiswe isignali ye-analog yokufaka noma isignali yedijithali, bese kuyenza ibe yidijithali. Ngemuva kwalokho isigaba sesignali sihanjiswa yidivayisi yokucubungula izimpawu zedijithali. Izinkomba eziyinhloko zifaka phakathi ibhendi yemvamisa yokusebenza, ububanzi besigaba, ama-control bits, i-phase flatness, ukunemba kwesigaba, ukulahleka kokufakwa, isilinganiso samagagasi okuma kwe-voltage, umthamo wamandla nokunye.

Izici zabo zifaka:

1. Izinga eliphezulu lokuzenzakalela: kungahlelwa noma kungalawulwa ngokusebenzisa isikhombikubona sekhompyutha, ngaphandle kokungenelela ngesandla, kuthuthukisa ukuthembeka kohlelo kanye nokuzinza. Kulesi simo, njengedivayisi yezifundazwe ezimbili, i-digital control phase shifter inezigaba ezahlukene zokufaka ezimweni ezahlukene kanye nama-frequency e-microwave.
2. Isigaba esiyisicaba singagcinwa ngisho nakuma-bandwidth abanzi.
3. Noma ngabe i-digital phase shifter yakhelwe kunethiwekhi enokufanisa okungekuhle kwe-impedance, akulula ukuyibamba ngezigaba.
4. akuthinteki umsindo emugqeni wokulawula.
5.fanisa amandla aphezulu kanye nokuhleleka.

Ngenxa yezici ezingenhla, i-Digital Step Phase Shifter isetshenziswa kabanzi kwezokuxhumana, i-radar, ukulinganisa imvamisa yomsakazo, imishini yezempi, njll., ngeziqondiso ezilandelayo zohlelo lokusebenza:

1. Nikeza umehluko wesigaba olawulwayo wezibonakaliso ze-RF
2. Shintsha i-engela yesigaba sokudlulisa yenethiwekhi enamachweba amabili
3. Isigaba se-antenna ye-radar ehlukaniswe ngezigaba kanye nesixhumanisi sokuxhumana esilawulwayo esiqondiswayo siyalawulwa. Isigaba esihlobene sento ngayinye ye-elimination loop ye-high linearity amplifier siyalawulwa.
4. Ukwakha imisebe.
5. Ukukhanselwa kwesiginali.

I-Qualwaveinikeza ukulahlekelwa okuphansi kokufakwa kanye nama-shifter esigaba asebenza ngesandla anamandla aphezulu ukusuka ku-DC kuya ku-40GHz. Ukulungiswa kwesigaba kufikela ku-360°/GHz, izinhlobo ze-Connector yi-SMA kanye ne-2.92mm. Futhi ukuphathwa kwamandla okumaphakathi kufikela ku-100 watts.
