Malangizo a Kamangidwe
Mapangidwe A board
Table 1 ikufotokoza malangizo omwe akugwirizana ndi manambala omwe ali mu Chithunzi 3 ndi Chithunzi 4.
Table 1. Maupangiri a Ma module
| Buku | Kufotokozera Malangizo |
| 1 | Sungani kuyandikira kwa njira yapansi pafupi ndi pad. |
| 2 | Osathamangitsa zowunikira pansi pa module pagawo lomwe gawoli layikidwa. |
| 3 | Khalani ndi nthaka yathunthu kutsanulira mu wosanjikiza 2 kuti muthe kutentha. |
| 4 | Onetsetsani ndege yapansi yolimba ndi pansi pansi pa gawo la dongosolo lokhazikika komanso kutaya kwa kutentha. |
| 5 | Wonjezerani pansi kutsanulira mu wosanjikiza woyamba ndipo khalani ndi zowona zonse kuchokera pagawo loyamba pazigawo zamkati, ngati n'kotheka. |
| 6 | Zizindikiro za ma Signal zitha kuyendetsedwa pagawo lachitatu pansi pa nthaka yolimba komanso gawo loyika ma module. |
Chithunzi 5 ikuwonetsa kapangidwe kake ka PCB. Orcawest Holdings, LLC dba EI Medical Imaging imalimbikitsa kugwiritsa ntchito 50-Ω machesi otsekereza potsata mlongoti ndi 50-Ω kutsatira masanjidwe a PCB.
Chithunzi 6 ndi Chithunzi 7 chikuwonetsa machitidwe abwino a kachitidwe ka mlongoti ndi njira yotsatirira ya RF.
ZINDIKIRANI: Zotsatira za RF ziyenera kukhala zazifupi momwe zingathere. Mlongoti, RF traces, ndi ma modules ayenera kukhala m'mphepete mwa PCB. Kuyandikira kwa mlongoti ku mpanda ndi zinthu zotchinga ziyeneranso kuganiziridwa.
Table 2. Antenna ndi RF Trace Routing Layout Guidelines
| Buku | Kufotokozera Malangizo |
| 1 | Zakudya za RF trace antenna ziyenera kukhala zazifupi momwe zingathere kupitilira zomwe zili pansi. Panthawi imeneyi, mphutsi imayamba kuphulika. |
| 2 | Kupindika kwa RF kuyenera kuchitika pang'onopang'ono ndikupindika pafupifupi madigiri 45 ndikutsata miter. Kutsata kwa RF sikuyenera kukhala ndi ngodya zakuthwa. |
| 3 | Kutsata kwa RF kumayenera kukhala ndi kusokera pansi pa ndege pafupi ndi RF mbali zonse ziwiri. |
| 4 | Kutsata kwa RF kuyenera kukhala kosalekeza (microstrip transmission line). |
| 5 | Kuti mupeze zotsatira zabwino, RF trace layer iyenera kukhala yosanjikiza pansi pamunsi pa RF track. Gawo la pansi liyenera kukhala lolimba. |
| 6 | Pasapezeke zotsalira kapena pansi pansi pa gawo la mlongoti. |
Chithunzi 8 chikuwonetsa kutalika kwa mlongoti wa MIMO. Mtunda wapakati pa ANT1 ndi ANT2 uyenera kukhala wokulirapo kuposa theka la kutalika kwa mafunde (62.5 mm pa 2.4 GHz).
Tsatirani malangizo awa:
- Panjira yoperekera magetsi, njira yamagetsi ya VBAT iyenera kukhala m'lifupi 40-mil.
- Kutsata kwa 1.8-V kuyenera kukhala m'lifupi ndi 18-mil.
- Pangani kutsata kwa VBAT mokulirapo momwe mungathere kuti mutsimikizire kuchepetsedwa kwa inductance ndikutsata kukana.
- Ngati n'kotheka, tetezani mayendedwe a VBAT ndi nthaka pamwamba, pansi, ndi pambali pazithunzizo.
Tsatirani malangizo awa amasinthidwe a digito:
- Njira zamtundu wa SDIO (CLK, CMD, D0, D1, D2, ndi D3) mofananira wina ndi mnzake komanso zazifupi momwe zingathere (zosakwana 12 cm). Kuphatikiza apo, mzere uliwonse uyenera kukhala wofanana kutalika. Onetsetsani kuti pali malo okwanira pakati pa mayendedwe (oposa nthawi 1.5 m'lifupi mwake kapena pansi) kuti muwonetsetse kuti ma siginecha ali abwino, makamaka pakutsata kwa SDIO_CLK. Kumbukirani kusunga izi kutali ndi zina zama digito kapena ma analogi. TI imalimbikitsa kuwonjezera zotchingira pansi mozungulira mabasi awa.
- Zizindikiro za wotchi ya digito (wotchi ya SDIO, wotchi ya PCM, ndi zina zotero) ndi magwero a phokoso. Sungani zizindikiro za zizindikirozi mwachidule momwe mungathere. Ngati n'kotheka, sungani chilolezo chozungulira zizindikirozi.
Zambiri Zamanja kwa Wogwiritsa Ntchito Mapeto
Wophatikizira wa OEM akuyenera kudziwa kuti asapereke zambiri kwa wogwiritsa ntchito momwe angayikitsire kapena kuchotsa gawo la RF mu bukhu la wogwiritsa ntchito la chomaliza chomwe chimaphatikiza gawoli. Buku la ogwiritsa ntchito likhala ndi zonse zofunikira pakuwongolera / machenjezo monga momwe zikuwonetsedwera m'bukuli.

Chipangizochi chikugwirizana ndi Gawo 15 la Malamulo a FCC. Kugwira ntchito kumadalira zinthu ziwiri izi: (1) Chipangizochi sichingabweretse kusokoneza koopsa, ndipo (2) chipangizochi chiyenera kuvomereza kusokoneza kulikonse komwe kumalandira, kuphatikizapo kusokoneza komwe kungayambitse ntchito yosayenera.
Zipangizozi zayesedwa ndipo zapezeka kuti zikugwirizana ndi malire a chipangizo cha digito cha Gulu B, motsatira Gawo 15 la Malamulo a FCC. Malire awa adapangidwa kuti apereke chitetezo chokwanira ku kusokoneza koyipa pakukhazikitsa nyumba. Chipangizochi chimapanga, chimagwiritsa ntchito komanso chimatha kuwunikira mphamvu zamawayilesi ndipo, ngati sichinayikidwe ndikugwiritsidwa ntchito motsatira malangizo, chikhoza kuyambitsa kusokoneza kwa mawayilesi. Komabe, palibe chitsimikizo kuti kusokoneza sikudzachitika mu unsembe winawake. Ngati chida ichi chikuyambitsa kusokoneza koyipa kwa wailesi kapena kulandila wailesi yakanema, komwe kungadziwike ndikuzimitsa ndi kuyatsa zida, wogwiritsa ntchitoyo akulimbikitsidwa kuyesa kusokoneza ndi chimodzi mwazinthu izi:
- Yankhanitsaninso kapena sinthani mlongoti wolandira.
- Wonjezerani kulekana pakati pa zida ndi wolandila.
- Lumikizani chipangizocho munjira yosiyana ndi yomwe wolandila amalumikizidwa.
- Funsani wogulitsa kapena wodziwa ntchito pa wailesi/TV kuti akuthandizeni.
Kusintha kulikonse kapena kusintha komwe sikunavomerezedwe ndi gulu lomwe lili ndi udindo wotsatira malamulowo kungathe kulepheretsa wogwiritsa ntchito kugwiritsa ntchito chipangizochi.
Chotumizira ichi sichiyenera kukhala pamalo amodzi kapena kugwira ntchito limodzi ndi mlongoti wina uliwonse kapena chopatsira.
Ndemanga ya Industry Canada
Chipangizochi chimagwirizana ndi mulingo wa RSS wopanda laisensi wa Industry Canada. Kugwira ntchito kumadalira zinthu ziwiri izi:
- Chipangizochi sichikhoza kuyambitsa kusokoneza, ndi
- Chipangizochi chiyenera kuvomereza kusokonezedwa kulikonse, kuphatikizapo kusokoneza komwe kungayambitse ntchito yosayenera ya chipangizocho.
KODI ICES-3 (B) / NMB-3 (B)
Chipangizocho chitha kungosiya kufalitsa ngati palibe chidziwitso chotumizira, kapena kulephera kugwira ntchito. Zindikirani kuti izi sizinali zoletsa kufalitsa mauthenga olamulira kapena chizindikiro kapena kugwiritsa ntchito ma code obwerezabwereza pamene akufunikira luso lamakono.
- Chipangizo chogwirira ntchito mu bandi 5150-5250 MHz ndichongogwiritsa ntchito m'nyumba kuti muchepetse kusokoneza koyipa kwa makina a satana am'manja;
- Kupindula kwakukulu kwa mlongoti komwe kumaloledwa pazida zamagulu 5250-5350 MHz ndi 5470-5725 MHz ziyenera kutsata malire a eirp; ndi
- Kupindula kwakukulu kwa mlongoti komwe kumaloledwa pazida za bandi 5725–5825 MHz kudzayenderana ndi malire a eirp otchulidwira potengera nsonga ndi nsonga momwe kuli koyenera.
Kuphatikiza apo, ma radar amphamvu kwambiri amaperekedwa ngati ogwiritsa ntchito oyambira (ie ogwiritsa ntchito patsogolo) amagulu a 5250-5350 MHz ndi 5650-5850 MHz ndikuti ma radar awa angayambitse kusokoneza ndi/kapena kuwononga zida za LE-LAN.
Chidziwitso Chokhudzana ndi Ma radiation
Zida izi zimagwirizana ndi malire a ma radiation a FCC / IC omwe amakhazikitsidwa m'malo osalamulirika. Zipangizozi ziyenera kukhazikitsidwa ndikugwiritsidwa ntchito osachepera 20 cm pakati pa radiator & thupi lanu.
Malizitsani Kulemba Zamalonda
Pamene gawoli likuyikidwa mu chipangizo chothandizira, chizindikiro cha FCC / IC ID chiyenera kuwoneka pawindo pa chipangizo chomaliza kapena chiyenera kuwoneka pamene gulu lolowera, chitseko kapena chivundikiro chiri mosavuta.
kuchotsedwa. Ngati sichoncho, lebulo yachiwiri iyenera kuyikidwa kunja kwa chipangizo chomaliza chomwe chili ndi mawu otsatirawa:
"Ili ndi FCC ID: XMO-WL18DBMOD”
"Muli ndi IC: Chithunzi cha 8512A-WL18DBMOD
ID ya FCC/IC ID ya wolandirayo ingagwiritsidwe ntchito pokhapokha ngati zofunikira zonse za FCC/IC zakwaniritsidwa.
Chipangizochi chimapangidwira ophatikiza a OEM okha pamikhalidwe iyi:
- Mlongoti uyenera kuyikidwa kuti 20 cm ikhalebe pakati pa mlongoti ndi ogwiritsa ntchito.
- Gawo la transmitter silingakhale limodzi ndi ma transmitter kapena mlongoti wina uliwonse.
- Chowulutsira pawailesi ichi chikhoza kugwira ntchito pogwiritsa ntchito mlongoti wamtundu wamtundu komanso phindu lalikulu (kapena lochepera) lovomerezedwa ndi Texas Instrument. Mitundu ya tinyanga tating'ono yomwe sinaphatikizidwe pamndandanda, wokhala ndi phindu lalikulu kuposa phindu lomwe lasonyezedwa pamtunduwu, ndizoletsedwa kugwiritsidwa ntchito ndi chowulutsira ichi.
