Izixubi Ezilinganiselayo Ze-Microwave

Ama-Power Balanced Mixers yidivayisi yesekethe ehlanganisa izimpawu ezimbili ndawonye ukuze ikhiqize isignali yokuphuma. Kuyasiza ukuthuthukisa ukuzwela, ukukhetha, ukuzinza kanye nokuvumelana kwenkomba yekhwalithi yomamukeli.

Izici zayo zifaka:

1. Ukucindezela izimpawu ezilahlekile: Ngokusebenzisa isakhiwo sesekethe esilinganiselayo, ungacindezela ngempumelelo izimpawu ezilahlekile kanye nokuphazamiseka ngaphandle kwesignali yokufaka, uthuthukise ubumsulwa kanye nekhwalithi yesignali.
2. Ukuphambuka okuphansi kwe-intermodulation: Ukukhiqizwa kokuphambuka kwe-intermodulation kungancishiswa ngoba isakhiwo sayo esilinganiselayo sinikeza imiphumela yokuxuba enembile nenembile ngokulwa nemiphumela emibi yezingxenye ezingezona eziqondile.
3. Ukusetshenziswa kwebhendi ebanzi: ngobubanzi bebhendi ebanzi, ukuxuba kanye nokucubungula isignali kungatholakala ebangeni elibanzi lemvamisa.
4. Ukulingana okuphezulu: kunganikeza amasignali okukhipha anembile, futhi kuthuthukise kakhulu ukuzwela kanye nobubanzi obuguqukayo besistimu.

Ama-RF Balanced mixers ngokuvamile asetshenziswa kulezi zinsimu ezilandelayo:

1. Izinhlelo zokuxhumana: Ama-mixer alinganiselayo asetshenziswa kabanzi ezinhlelweni zokuxhumana zokuguqulwa kwama-frequency, ukuguqulwa kwama-modulation kanye nokususwa kwawo, i-Doppler radar, i-radio frequency receiver kanye nezinye izinkambu. Iyakwazi ukuhlanganisa amasignali ama-frequency ahlukene ndawonye, okuvumela ukuthi adluliselwe futhi acutshungulwe phakathi kwama-frequency band ahlukene.
2. Imishini yomsakazo: Emishinini yomsakazo, abaxubi abalinganisiwe bangasetshenziswa ukushintshashintsha kanye nokususa izimpawu ezitholiwe nezithunyelwe. Iyakwazi ukuxuba izimpawu ezitholiwe ndawonye ukukhiqiza isignali ye-baseband, noma ukuxuba izimpawu ze-baseband ndawonye ukukhiqiza isignali eshintshiwe.
3. Izinhlelo zokuxhumana eziphansi nezesathelayithi: Izixubi ezilinganisela imvamisa yomsakazo zisetshenziswa kabanzi ezinhlelweni zokuxhumana eziphansi nezesathelayithi zokuguqulwa kwebhendi, izihlanganisi zemvamisa, imithombo yesignali kanye nezixubi.
4. Uhlelo lwe-radar: Kuhlelo lwe-radar, i-millimeter wave balanced mixer ingasetshenziswa ekulinganisweni kwejubane le-Doppler, ukuguqulwa kwemvamisa, ukucindezelwa kwe-pulse kanye nezinye izinqubo zokucubungula.
5. Amathuluzi okuhlola nokulinganisa: Ama-mixer alinganiselayo e-Coaxial angasetshenziswa futhi kumathuluzi okuhlola nokulinganisa ukuhlaziywa kwesignali, ukuguqulwa kwemvamisa, ukuhlaziywa kwe-spectrum kanye nezinye izinhlelo zokusebenza ukunikeza imiphumela yokulinganisa enembile nethembekile.

I-Qualwaveinikeza ukulahleka kokuguqulwa okuphansi kanye nama-mixer okuhlukaniswa okuphezulu ebangeni elibanzi kusukela ku-1MHz kuya ku-110GHz. Ama-mixer ethu asetshenziswa kabanzi ezindaweni eziningi.
