5.4.1 Layoutandparts
RF traces from OSDI module pads W10 and W16 to the antenna must be made using micro-strip traces. This micro-strip trace must
respect the design of the Gerber file associated with the following figures in order to obtain a uniform transmission line with a characteristic
impedance of 50 ohms. The reference trace design is shown as the green trace along with the side copper filled with vias on the left side
of Figure 7 where components G8, G10, G15, G16 and G18 are not installed; they were options on the reference board for future uses;
these uses are not FCC authorized yet. As preliminary information the traces width of all sections are all 0.27mm and the length of each
section, starting from the LGA pad to J53 connector are: LGA pad to G7: 15.38mm; G7 to G9: 12.37mm; G9 to G17: 6.7mm; G17 to R52:
2.1mm; R52 to J53: 7.2mm. However, refer to associated Gerber files for more accurate details on dimensions and refer to Trilliant
Networks Inc for more details on the Gerber files. Table 2 shows the parts used in the reference trace design.
