I-Surface Mount Baluns RF Microwave Millimeter Wave mm wave
I-Surface Mount Baluns (Ama-Balance-Unbalance transformer) ayizingxenye ezikhethekile ze-RF/microwave eziklanyelwe ukuguqula phakathi kwamasignali kagesi abhalansile nangalingani kumasekhethi anemvamisa ephezulu. Ekhiqizwe kusetshenziswa ubuchwepheshe befilimu emincane ethuthukisiwe noma ubuchwepheshe be-ceramic ye-multilayer, lawa madivayisi ahlangene ahlinzeka ngoguquko olubalulekile lwe-impedance namandla okwenqaba imodi evamile. Njengamabhulokhi wokwakha abalulekile kumasistimu angenantambo, asiza ubuqotho besignali obuphelele kuyilapho ehambisana nezinqubo zokuhlanganisa ezizenzakalelayo zesimanje. Idizayini yabo ye-surface-mount ibenza balungele ukukhiqizwa kwevolumu ephezulu kukho konke ukuxhumana ngocingo, i-IoT, kanye nezicelo zama-electronics abathengi.
Izici Eziyinhloko Nezimpawu:
1. Ukusebenza kwemvamisa ephezulu kanye nobunjiniyela obunembayo
Ukusebenza kwe-Broadband: Sekela amafrikhwensi abanzi (kusuka ku-MHz amaningana kuya kumabhendi e-GHz amaningi) ngokusebenza okungaguquguquki kuwo wonke ama-bandwidth acacisiwe, okuqeda isidingo sezingxenye eziningi ze-narrowband.
Ukuguqulwa kwe-impedance okunembayo: Nikeza izilinganiso ezinembile zokuguqulwa kwe-impedance (isb, 1:1, 1:4, 4:1) ngokubekezelelana okuqinile (±5% okujwayelekile) ukuze kufane nezidingo zesistimu ehlukile kanye nekuphela kwesikhathi esisodwa.
Ibhalansi ye-amplitude/isigaba esihle kakhulu: Gcina ibhalansi ye-amplitude ephakeme (imvamisa engu-±0.5 dB) kanye nebhalansi yesigaba (imvamisa engu-±5 degrees) ukuze wenqabele umsindo wemodi evamile.
Ukulahlekelwa kokufaka okuphansi: Zuza ukulahlekelwa kwesignali okuncane (okuphansi njengokungu-0.5 dB kuye ngefrikhwensi) ngokusebenzisa ukuhlanganisa kazibuthe okulungiselelwe kanye nezinto ze-dielectric ezilahlekelwa kancane.
2. Amakhono okupakisha athuthukile kanye nokuhlanganisa
Amafomu ahlangene: Atholakala kumaphakheji ajwayelekile embonini kanye nosayizi bangokwezifiso bemiklamo ebamba isikhala.
Ukuhambisana kwe-Surface-mount: Ihambisana nemishini yokukhetha nendawo ezenzakalelayo kanye nezinqubo zokuphinda zifakwe emanzini, okuvumela ukukhiqizwa kwevolumu ephezulu.
Ukwakhiwa okuqinile: Sebenzisa ama-ceramic, ama-ferrite, noma ama-substrates ayinhlanganisela aneziphetho zokuqeda (Ni/Sn, Au) ezifanele izimo zemvelo ezinzima.
I-ESD nokuvikela okushisayo: Izici zokuvikela ezihlanganisiwe zimelana nemicimbi ye-ESD (kufika ku-2kV HBM) namazinga okushisa okusebenza.
3. Ukuthembeka okuthuthukisiwe kanye nokwenza kahle okuqondene nohlelo lokusebenza
Ukusebenza kokuzihlukanisa okuphezulu: Nikeza ukuhlukaniswa kwembobo ukuya ethekwini ngokuvamile okudlula u-20 dB ukuvimbela ukuhlangana kwesignali okungafunwa.
Amandla okuphatha: Sekela amazinga wamandla ukusuka kuma-milliwatts ukuya kuma-watts amaningana kuye ngosayizi wephakheji kanye nomklamo.
Ukulungiselela amamodeli athile: Kutholakala ekucushweni okulungiselelwe izinhlelo zokusebenza ezithile (i-Wi-Fi, iselula, i-Bluetooth, njll.) enamapharamitha we-S anesici.
Izicelo:
1. Amasistimu okuxhumana okungenazintambo
Ingqalasizinda yeselula: Ama-transceivers esiteshi esiyisisekelo, amasistimu amakhulu we-MIMO, namaseli amancane adinga ukufanisa i-impedance kanye nokwenqatshwa kwemodi evamile kuma-front-ends e-RF.
Amamojula e-Wi-Fi/Bluetooth: Nika amandla ukuxhumeka kwe-antenna okuhlukile futhi uthuthukise ukuzwela komamukeli kumabhendi efrikhwensi angu-2.4/5/6 GHz.
Imishini ye-5G NR: Yenza kube lula ukusebenza kwe-mmWave kanye ne-sub-6 GHz kumishini yomsebenzisi nengqalasizinda yenethiwekhi.
2. I-Consumer electronics kanye namadivayisi we-IoT
Ama-Smartphone/Amathebulethi: Nika amandla ukuklama kwesigaba se-RF ehlangene ngobuqotho obuthuthukisiwe besignali kumaselula, i-Wi-Fi, kanye nezamukeli ze-GPS.
Izinto zikagesi ezigqokekayo: Nikeza ngezixazululo zokuguqulwa kwesignali encane zokuqapha ezempilo namamojula okuxhumana.
Amadivayisi ahlakaniphile asekhaya: Sekela ukuxhumana okungenantambo kuzinzwa ze-IoT, amahabhu, nezilawuli ezidinga ukusebenza okuthembekile kwe-RF.
3. Imishini yokuhlola neyokulinganisa
Abahlaziyi benethiwekhi yeVector: Isebenza njengezingxenye zokulinganisa kanye nezilungiselelo zokuhlola ukuze uthole izilinganiso ezinembile ezihlukile.
