Ukuguqulwa Okuphansi Ukulahlekelwa Okuphezulu Kwe-Isolation Harmonic Mixers
I-Harmonic mixer iyithuluzi elingahlanganisa amasignali amafrikhwensi ahlukene ukuze kuzuzwe ukuguqulwa kwemvamisa nokucutshungulwa kwesignali.
Umsebenzi oyinhloko we-mixer ukuhlanganisa ngokungekho umugqa amasignali amabili noma ngaphezulu amafrikhwensi ahlukene, ngaleyo ndlela ukhiqize izingxenye zesiginali ezintsha futhi uzuze izici ezinjengokuguqulwa kwemvamisa, ukuhlanganiswa kwamafrikhwensi, nokukhetha imvamisa. Ngokukhethekile, i-mixer ingaguqula imvamisa yesiginali yokufaka ibe ibanga lemvamisa oyifunayo ngenkathi igcina izici zesiginali yoqobo.
Umgomo wobuchwepheshe wabaxube be-harmonic ikakhulukazi uncike ezicini ezingaqondile zama-diode, futhi imvamisa edingekayo emaphakathi ikhethwa ngamasekhethi afanayo namasekhethi okuhlunga ukuze kuzuzwe ukuguqulwa kwemvamisa kwamasiginali. Lobu buchwepheshe abugcini nje ngokwenza lula ukwakheka kwesekethe futhi bunciphise umsindo, kodwa futhi kunciphisa kakhulu ukulahlekelwa kokuguqulwa kwemvamisa, ukuthuthukisa ukusebenza kwesistimu nokusebenza kahle. Ngenxa yokuthi izixube ze-harmonic zingasetshenziswa kuma-millimeter wave kanye nama-frequency band we-terahertz, lokhu kungadambisa kakhulu inkinga yokuxubana kwesistimu futhi kuthuthukise ukusebenza kwabamukeli abanezakhiwo zokuguqula imvamisa eqondile.
Izinhlelo zokusebenza Eziyinhloko:
1. Ekuxhumaneni okungenantambo, izixube ze-harmonic zivame ukusetshenziswa kuma-frequency synthesizers, ama-frequency converters, kanye nezingxenye ze-RF front-end ukuze zisekele ukusebenza okuvamile kwamasistimu okuxhumana okungenazintambo ngokuguqulwa kwemvamisa nokucutshungulwa kwamasignali.
2. Abaxube be-Harmonic banezinhlelo zokusebenza ezibalulekile ezinhlelweni ze-radar zokwamukela nokucubungula amasignali e-radar, ukuqinisekisa ukunemba nokuthembeka kwesistimu ye-radar.
3. Izixube ze-Harmonic zisetshenziswa kakhulu emikhakheni eminingi njengokuhlaziywa kwe-spectrum, izinhlelo zokuxhumana, ukuhlolwa nokulinganisa, nokukhiqizwa kwesignali. Bathuthukisa ukusebenza kwesistimu nokuthembeka ngokuhlinzeka ngokuguqulwa kwemvamisa nokucubungula isignali, ukuqinisekisa ikhwalithi yokudluliselwa kwesignali nokuzinza kwesikhathi eside kwemishini.
Inkampani Qualwaves Inc.Inikeza ama-harmonic mixers asebenza kusuka ku-18 kuye ku-30GHz. Izixube zethu ze-harmonic zisetshenziswa kabanzi ezinhlelweni eziningi.
