Tafura 1 inotsanangura nhungamiro inoenderana nenhamba dzereferenzi muFigure 3 uye Mufananidzo 4.
Tafura 1. Module Layout Guidelines
| Reference | Tsanangudzo Yekutungamira |
| 1 | Chengetedza kuswedera kwevhu vias padyo nepadhi. |
| 2 | Usamhanye zviratidzo zvechiratidzo pasi peiyo module pane iyo layer inoiswa module. |
| 3 | Iva nevhu rakakwana rekudira mu layer 2 yekupisa kupisa. |
| 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 | Signal traces inogona kumhanyirwa pachikamu chechitatu pasi peiyo yakasimba yepasi layer uye module inokwirisa layer. |
Mufananidzo 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.
CHERECHEDZA: 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.
Tafura 2. Antenna uye RF Trace Routing Layout Guidelines
| Reference | Tsanangudzo Yekutungamira |
| 1 | Iyo RF inoteedzera antenna feed inofanirwa kunge ipfupi sezvinobvira kupfuura referensi yepasi. Panguva ino, mutsara unotanga kupenya. |
| 2 | RF trace bend inofanirwa kunge ichibhenda zvishoma nezvishoma neinopengera kubhenda kwe45 degrees ine trace mitered. RF traces haifanirwe kuve nemakona akapinza. |
| 3 | Mateki eRF anofanirwa kuve nekusona pasi pendege padivi peRF trace pamativi ese. |
| 4 | RF traces inofanirwa kuve inogara iine impedance (microstrip transmission line). |
| 5 | Kuti uwane mibairo yakanaka, iyo RF inoteedzera pasi layer inofanirwa kunge iri pasi pasi ipapo pazasi peRF trace. Nzvimbo yepasi inofanira kuva yakasimba. |
| 6 | Hapafanirwe kuve nematehwe kana pasi pasi pechikamu cheantenna. |
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).
Tevedza aya madhairekitori ekupa nzira:
- Kune magetsi ekufambisa nzira, simba rekutsvaga VBAT rinofanira kunge riine 40-mil paupamhi.
- Iyo 1.8-V trace inofanirwa kunge yakafara 18-mil.
- Ita VBAT traces yakafara sezvinobvira kuve nechokwadi kuderedzwa inductance uye kutsvaga kuramba.
- If possible, shield VBAT traces with ground above, below, and beside the traces.
Follow these digital-signal routing guidelines:
- Nzira yeSDIO siginecha inoteedzera (CLK, CMD, D0, D1, D2, uye D3) yakaenzana kune imwe neimwe uye ipfupi sezvinobvira (pasi pe12 cm). Mukuwedzera, mutsara wega wega unofanirwa kunge wakareba zvakafanana. Ita shuwa nzvimbo yakakwana pakati pezvinotevera (yakakura kupfuura 1.5 times the trace wide kana pasi) kuve nechokwadi chemhando yechiratidzo, kunyanya yeSDIO_CLK trace. Rangarira kuchengeta aya matera kure kubva kune mamwe madhijitari kana analog siginecha inoteedzera. TI inokurudzira kuwedzera kudzivirira kwepasi kwakatenderedza mabhazi aya.
- 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.
