Module Layout Guidelines Reference Guideline Description Keep the proximity of ground vias close to the pad. 1 2 3 4 5 6 Do not run signal traces underneath the module on the layer where the module is mounted. Have a complete ground pour in layer 2 for thermal dissipation. Ensure a solid ground plane and ground vias under the module for stable system and thermal dissipation. Increase ground pour in the first layer and have all traces from the first layer on the inner layers, if possible. Signal traces can be run on a third layer under the solid ground layer and the module mounting layer.

Trace Design for the PCB Layout Figure 14 shows layer 1 with the trace to the antenna over ground layer 2. Figure 14. Layer 1 Combined With Layer 2 Figure 15 and Figure 16 show instances of good layout practices for the antenna and RF trace routing. NOTE: 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. 14 WL1837MODCOM8I WLAN MIMO and Bluetooth Module Evaluation Board for TI Sitara Platform SWRU382 November 2014 Submit Documentation Feedback Copyright 2014, Texas Instruments Incorporated www.ti.com Layout Guidelines Figure 15.

Antenna and RF Trace Routing Layout Guidelines Reference Guideline Description 1 2 3 4 5 6 The RF trace antenna feed must be as short as possible beyond the ground reference. At this point, the trace starts to radiate. RF trace bends must be gradual with an approximate maximum bend of 45 degrees with trace mitered. RF traces must not have sharp corners. RF traces must have via stitching on the ground plane beside the RF trace on both sides. RF traces must have constant impedance (microstrip transmission line). For best results, the RF trace ground layer must be the ground layer immediately below the RF trace. The ground layer must be solid. There must be no traces or ground under the antenna section.

The distance between ANT1 and ANT2 must be greater than half the wavelength (62.5 mm at 2.4 GHz). Figure 17. MIMO Antenna Spacing Follow these supply routing guidelines:
For power supply routing, the power trace for VBAT must be at least 40-mil wide. The 1.8-V trace must be at least 18-mil wide. Make VBAT traces as wide as possible to ensure reduced inductance and trace resistance. If possible, shield VBAT traces with ground above, below, and beside the traces. Follow these digital-signal routing guidelines:
Route SDIO signal traces (CLK, CMD, D0, D1, D2, and D3) in parallel to each other and as short as possible (less than 12 cm). In addition, each trace must be the same length. Ensure enough space between traces (greater than 1.5 times the trace width or ground) to ensure signal quality, especially for the SDIO_CLK trace. Remember to keep these traces away from the other digital or analog signal traces. TI recommends adding ground shielding around these buses. 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. 7 Ordering Information Part number:

Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or enhanced plastic are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
