QHAGAMSHELANA NGOKU

I-Waveguide Manual Phase Shifters zizixhobo zokungenzi nto ezisetyenziselwa i-RF kunye nokusetyenzwa komqondiso we-microwave ezinokuthi zilungelelanise inqanaba lophawu. Zibalulekile kwizicelo ezifuna ulawulo oluchanekileyo lwesigaba somqondiso.

Injongo:

1. Ulungelelwaniso lweSigaba: I-microwave phase shifter isetyenziselwa ukulungelelanisa ngesandla isigaba somqondiso ukuphumeza ulawulo lwesigaba oluchanekileyo. Oku kubaluleke kakhulu ekufaniseni isigaba kunye nokuguqulwa kwesigaba.
2. Imbuyekezo yeSigaba: I-Millimeter wave shifts phase shifters isetyenziselwa ukuhlawulela impazamo yesigaba kwisistim kunye nokuqinisekisa ukuba isigaba somqondiso kwiindlela ezahlukeneyo sihambelana, ngaloo ndlela siphucula ukusebenza kwenkqubo.
3. I-Beamforming: Ngokulungelelanisa isigaba seyunithi nganye ye-eriyali kuluhlu lwe-eriyali, i-radio frequency phase shifter inokufikelela kwi-beamforming kunye ne-beam scanning.
4. Umdlalo weNqanaba: Kwiinkqubo zamatshaneli amaninzi, ii-mm-wave phase shifters zisetyenziselwa ukuqinisekisa ukuba izigaba zetshaneli nganye ziyahambelana, ngaloo ndlela kuzuzwa ukuhambelana kwesigaba.

Isicelo:

I-RF phase shifter inoluhlu olubanzi lwezicelo kwinkalo yonxibelelwano lombane, kwaye omnye wemisebenzi yayo ephambili kukulinganisa isigaba.
1. Kwiinkqubo zonxibelelwano, i-phase shifters ingasetyenziselwa ukuvumelanisa iimpawu ezivela kwimithombo eyahlukeneyo yesignali okanye iindlela zokuqinisekisa ukuba zifika ekupheleni kokufumana ngesigaba esichanekileyo. Ngokulungelelanisa isigaba somqondiso wegalelo, i-shifter yesigaba ihlangabezana nemfuneko yokulinganisa isigaba, ngaloo ndlela iphucula ukusebenza kwenkqubo kunye nokuzinza.
2. I-Phase shifters isetyenziswa ngokubanzi kwiinkqubo zokumodareyitha kunye ne-demodulation ukulungelelanisa isigaba seempawu ze-carrier carrier, ukuze kuphunyezwe ukuchithwa kwesignali kunye nokuqatshelwa kweendlela ezahlukeneyo zokumodareyitha (ezifana ne-PSK, i-QAM, njl.).
3. Ngokubhekiselele kwi-frequency synthesis, i-radio frequency phase shifters ingasetyenziselwa ukulungelelanisa isigaba semiqondiso kwiifrikhwensi ezahlukeneyo, ngaloo ndlela kufezekiswa injongo ye-frequency synthesis.
4. Unxibelelwano lwedijithali: Bidi.

Oku kudlala indima ebalulekileyo kwiinkalo ezifana nonxibelelwano lwamacingo kunye neenkqubo ze-radar.

Qualwaveibonelela Waveguide Manual Phase Shifters ukusuka 8.2 ukuya 12.4GHz. Ukulungelelaniswa kwesigaba ukuya kwi-360 ° / GHz.
