Mafunde a RF Microwave a pamwamba pa Baluns
Ma Surface Mount Baluns (ma transformer a Balance-Unbalance) ndi zida zapadera za RF/microwave zomwe zimapangidwa kuti zisinthe pakati pa ma siginecha amagetsi olinganizidwa ndi osalinganizidwa m'ma circuits apamwamba. Zopangidwa pogwiritsa ntchito ukadaulo wapamwamba wa thin-film kapena multilayer ceramic, zidazi zing'onozing'ono zimapereka kusintha kofunikira kwa impedance komanso kuthekera kokana njira yodziwika bwino. Monga zomangira zofunika kwambiri m'makina opanda zingwe, zimathandiza kuti zizigwira bwino ntchito ya siginecha pomwe zikutsatira njira zamakono zosonkhanitsira zokha. Kapangidwe kake koyika pamwamba pa siginecha kamapangitsa kuti zikhale zabwino kwambiri popanga zinthu zambiri pa intaneti, IoT, ndi ma electronics.
Zinthu Zofunika Kwambiri ndi Makhalidwe:
1. Kuchita bwino kwambiri komanso kulondola kwaukadaulo
Kugwira ntchito kwa Broadband: Kuthandizira ma frequency osiyanasiyana (kuyambira ma MHz angapo mpaka ma multi-GHz) ndi magwiridwe antchito ofanana m'ma bandwidth enaake, kuchotsa kufunikira kwa zigawo zingapo za narrowband.
Kusintha kwa impedance kolondola: Perekani ma ratio olondola a impedance conversion (monga 1:1, 1:4, 4:1) ndi kulekerera kolimba (± 5% yachizolowezi) kuti igwirizane ndi zofunikira za dongosolo losiyana ndi limodzi.
Kulinganiza bwino kwa ma amplitude/gawo: Sungani bwino ma amplitude (nthawi zambiri ± 0.5 dB) ndi ma phase balance (nthawi zambiri ± madigiri 5) kuti phokoso la common-mode lisamagwire bwino ntchito.
Kutayika kochepa kwa ma insertion: Pezani kutayika kochepa kwa ma signal (kotsika mpaka 0.5 dB kutengera kuchuluka kwa ma frequency) kudzera mu optimized magnetic coupling ndi low-loss dielectric materials.
2. Kukonza bwino ndi kuphatikiza zinthu
Zinthu zazing'ono: Zimapezeka m'maphukusi ofanana ndi mafakitale komanso kukula koyenera kwa mapangidwe okhala ndi malo ochepa.
Kugwirizana ndi malo oimikapo: Kumagwirizana ndi zida zodzipangira zokha komanso njira zosinthira magetsi, zomwe zimathandiza kupanga zinthu zambiri.
Kapangidwe kolimba: Gwiritsani ntchito zinthu zopangidwa ndi ceramic, ferrite, kapena composite zokhala ndi zomaliza (Ni/Sn, Au) zoyenera nyengo zovuta.
ESD ndi chitetezo cha kutentha: Zida zotetezera zomwe zili mkati mwake zimapirira zochitika za ESD (mpaka 2kV HBM) ndi kutentha kwa ntchito.
3. Kudalirika kowonjezereka komanso kukonza bwino ntchito
Kuchita bwino kwambiri pakulekanitsa: Perekani kulekanitsa kwa ma doko kupita ku madoko komwe nthawi zambiri kumapitirira 20 dB kuti mupewe kulumikizana kwa chizindikiro chosafunikira.
Kutha kugwiritsa ntchito mphamvu: Kuthandizira kuchuluka kwa mphamvu kuyambira ma milliwatts mpaka ma watts angapo kutengera kukula kwa phukusi ndi kapangidwe kake.
Kukonza kwa mtundu: Kumapezeka m'makonzedwe okonzedwa kuti agwiritsidwe ntchito pazinthu zinazake (Wi-Fi, foni yam'manja, Bluetooth, ndi zina zotero) ndi ma S-parameter odziwika bwino.
Mapulogalamu:
1. Makina olumikizirana opanda zingwe
Zomangamanga za mafoni: Ma transceivers a siteshoni ya base, machitidwe akuluakulu a MIMO, ndi maselo ang'onoang'ono omwe amafunika kufananiza impedance ndi kukanidwa kwa common-mode mu RF front-ends.
Ma module a Wi-Fi/Bluetooth: Yambitsani kulumikizana kwa ma antenna osiyanasiyana ndikuwonjezera mphamvu ya wolandila mu ma frequency band a 2.4/5/6 GHz.
Zipangizo za 5G NR: Zimapangitsa kuti mmWave ndi sub-6 GHz zigwiritsidwe ntchito pokonza ma signaling mu zida za ogwiritsa ntchito komanso zomangamanga za netiweki.
2. Zipangizo zamagetsi ndi zipangizo za IoT
Mafoni/Mapiritsi: Yambitsani kapangidwe ka gawo la RF kakang'ono ndi kulimba kwa chizindikiro cha mafoni, Wi-Fi, ndi ma GPS.
Zipangizo zamagetsi zovalidwa: Perekani njira zosinthira zizindikiro zazing'ono kuti zigwiritsidwe ntchito poyang'anira thanzi ndi ma module olumikizirana.
Zipangizo zanzeru zapakhomo: Zimathandizira kulumikizana opanda zingwe mu masensa a IoT, ma hubs, ndi owongolera omwe amafunikira magwiridwe antchito odalirika a RF.
3. Zipangizo zoyesera ndi zoyezera
Zowunikira maukonde a mavekitala: Zimagwira ntchito ngati zida zowerengera ndi zida zoyesera kuti muyeze bwino kusiyana kwa zinthu.
Oyesa opanda zingwe: Yambitsani kuyesa bwino ma amplifiers, zosefera, ndi zida zina za RF
Machitidwe odalirika a chizindikiro: Amathandizira kuyesa kwa digito mwachangu kwambiri komwe kumaphatikizapo ma signaling osiyana (SerDes, PCIe, ndi zina zotero).
4. Zamagetsi zamagalimoto ndi zamafakitale
Machitidwe a V2X: Amathandizira mapulogalamu apadera olumikizirana afupiafupi (DSRC) ndi ma cellular-V2X (C-V2X).
Industrial IoT: Yambitsani kulumikizana kwamphamvu kwa opanda zingwe mu makina opangira zinthu ndi makina owunikira akutali.
Magawo a Telematics: Amapereka kusintha kodalirika kwa RF kwa ma module olumikizirana a GPS, mafoni, ndi satelayiti.
5. Zida zamagetsi zamlengalenga ndi zodzitetezera
Machitidwe a ndege: Amathandizira kulumikizana, kuyendetsa, ndi zida zowunikira kukwaniritsa zofunikira kwambiri zachilengedwe.
Kulankhulana ndi asilikali: Yambitsani maulalo opanda zingwe otetezeka m'makina onyamulika ndi anthu komanso omangika m'galimoto.
Machitidwe a radar: Kuthandizira kusintha koyenera/kosalinganika mu ma radar oyendetsedwa pang'onopang'ono komanso otsatiridwa.
Qualwaveimapereka mabaluni okhala pamwamba okhala ndi mitundu yosiyanasiyana kuti akwaniritse zosowa za makasitomala.
