IziKhokelo zokuBeka
Ubeko lweBhodi
Itheyibhile 1 ichaza izikhokelo ezihambelana neenombolo zereferensi kwi-Figure 3 kunye ne-4.
Uluhlu 1. IziKhokelo zokuYilwa kweeModyuli
| Isalathiso | Inkcazo yeSikhokelo |
| 1 | Gcina umgama wendlela yomhlaba kufutshane nephedi. |
| 2 | Sukubaleka imikhondo yophawu ngaphantsi kwemodyuli kumaleko apho imodyuli inyuswe khona. |
| 3 | Yiba nomhlaba opheleleyo wokugalela kumqolo we-2 wokutshatyalaliswa kwe-thermal. |
| 4 | Ensure a solid ground plane and ground vias under the module for stable system and thermal dissipation. |
| 5 | Increase ground pour in the first layer and have all traces from the first layer on the inner layers, if possible. |
| 6 | Iimpawu zomqondiso zingaqhutywa kuluhlu lwesithathu phantsi komgangatho oqinileyo womhlaba kunye nemodyuli yokunyuka kwemodyuli. |
Umzobo 5 shows the trace design for the PCB. Orcawest Holdings, LLC dba E.I. Medical Imaging recommends using a 50-Ω impedance match on the trace to the antenna and 50-Ω traces for the PCB layout.
Figure 6 and Figure 7 show instances of good layout practices for the antenna and RF trace routing.
PHAWULA: RF traces must be as short as possible. The antenna, RF traces, and modules must be on the edge of the PCB product. The proximity of the antenna to the enclosure and the enclosure material must also be considered.
Itheyibhile 2. I-Antenna kunye neRF Trace Routing Layout Guidelines
| Isalathiso | Inkcazo yeSikhokelo |
| 1 | I-RF trace feed eriyali kufuneka ibemfutshane kangangoko ngaphaya kwereferensi esemhlabeni. Ngeli xesha, umkhondo uqala ukugqama. |
| 2 | Ukugoba komkhondo we-RF kufuneka ngokuthe ngcembe kugobe ubuninzi obumalunga nama-45 degrees kunye ne-trace mitered. Umkhondo weRF akufuneki ube neekona ezibukhali. |
| 3 | Umkhondo weRF kufuneka ube nawo ngokuthungwa kwinqwelomoya ephantsi ecaleni komkhondo weRF macala omabini. |
| 4 | Umkhondo weRF kufuneka ube ne-impedance engaguqukiyo (umgca wothumelo wemicrostrip). |
| 5 | Ukuze ufumane iziphumo ezingcono, umaleko womhlaba womkhondo weRF kufuneka ube ngumaleko osemhlabeni ngokukhawuleza ngaphantsi komkhondo weRF. Umaleko womhlaba kufuneka womelele. |
| 6 | Kufuneka kungabikho mkhondo okanye umhlaba phantsi kwecandelo le-eriyali. |
Figure 8 shows the MIMO antenna spacing. The distance between ANT1 and ANT2 must be greater than half the wavelength (62.5 mm at 2.4 GHz).
Landela ezi zikhokelo zonikezelo lwendlela:
- Ukunika umbane umzila, umkhondo wamandla we-VBAT kufuneka ube ubuncinane be-40-mil ububanzi.
- Umkhondo we-1.8-V kufuneka ubuncinane ube yi-18-mil ububanzi.
- Yenza imikhondo ye-VBAT ibe banzi kangangoko ukuqinisekisa ukunciphisa inductance kunye nokulandelela ukuxhathisa.
- Ukuba kuyenzeka, khusela imikhondo ye-VBAT ngomhlaba ongentla, ongezantsi, nasecaleni kwemikhondo.
Follow these digital-signal routing guidelines:
- Umzila we-SDIO ulandelelwano lwesignali (CLK, CMD, D0, D1, D2, kunye ne-D3) ngokuhambelanayo kunye nokufutshane ngokusemandleni (ngaphantsi kwe-12 cm). Ukongeza, umkhondo ngamnye kufuneka ube nobude obufanayo. Qinisekisa indawo eyaneleyo phakathi kweetrayisi (enkulu kuno-1.5 amaxesha obubanzi bomkhondo okanye umhlaba) ukuqinisekisa umgangatho wesignali, ngakumbi umkhondo we-SDIO_CLK. Khumbula ukugcina le mikhondo kude kwezinye iitrayiti zedijithali okanye ze-analog. I-TI icebisa ukongeza ukukhuselwa komhlaba malunga nezi bhasi.
- Digital clock signals (SDIO clock, PCM clock, and so on) are a source of noise. Keep the traces of these signals as short as possible. Whenever possible, maintain a clearance around these signals.
Ulwazi lweManuwali kuMsebenzisi wokugqibela
Umdibanisi we-OEM kufuneka aqonde ukuba angaboneleli kumsebenzisi wokugqibela malunga nendlela yokufaka okanye ukususa le modyuli yeRF kwincwadana yomsebenzisi yemveliso yokugqibela edibanisa le modyuli. Incwadi yomsebenzisi wokugqibela iya kubandakanya zonke iinkcukacha ezifunekayo zolawulo/izilumkiso njengoko kubonisiwe kule ncwadana.

Phelisa ukuleyibhelishwa kweMveliso
When the module is installed in the host device, the FCC/IC ID label must be visible through a window on the final device or it must be visible when an access panel, door or cover is easily
removed. If not, a second label must be placed on the outside of the final device that contains the following text:
“Ine-ID yeFCC: XMO-WL18DBMOD”
“Iqulethe i-IC: 8512A-WL18DBMOD “
I-ID yeFCC/IC yomnikeli-nkonzo ingasetyenziswa kuphela xa zonke iimfuno zokuthotyelwa kweFCC/IC zihlangatyeziwe.
Esi sixhobo senzelwe kuphela abahlanganisi be-OEM phantsi kwezi meko zilandelayo:
- I-eriyali kufuneka ifakwe ngendlela yokuba i-20 cm igcinwe phakathi kwe-eriyali kunye nabasebenzisi.
- Imodyuli yothumelo ayinakubekwa ndawonye kunye naso nasiphi na esinye isidluliseli okanye i-eriyali.
- This radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved by Texas Instrument. Antenna types not included in the list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this transmitter.
| I-Antenna Gain (dBi) @ 2.4GHz | I-Antenna Gain (dBi) @ 5GHz |
| 3.2 | 4.5 |
Kwimeko apho le miqathango ayinakufezekiswa (umzekeloampulungelelwaniso oluthile lwelaptop okanye indawo edibeneyo nenye isithumeli), emva koko ugunyaziso lweFCC/IC alusathathwa njengesemthethweni kwaye iID yeFCC/IC ID ayinakusetyenziswa kwimveliso yokugqibela. Kwezi meko, umdibanisi we-OEM uya kuba noxanduva lokuphonononga kwakhona imveliso yokugqibela (kubandakanywa nomthumeli) kunye nokufumana isigunyaziso esahlukileyo seFCC/IC.
