WIRELESS & SENSING
7.5. Reference Design
It is recommended that this reference design (i.e. schematics, placement, layout, BOM,) is replicated in the final
application board to guarantee optimum performance.
7.5.1. Application Schematic
Figure 56: Reference Design Circuit Schematic
The reference design area is represented by the dashed rectangle. C12 is a DC blocking capacitor which protects
the SAW filter. It has been added for debug purposes could be removed for a direct antenna connection if there is
no DC bias is expected at the antenna port. Please note that C10 and C11 are not used.
7.5.2. PCB Layout
As illustrated in figures below, the layout has the following characteristics:
very compact (9x19mm) => can be easily inserted even on very small PCBs
standard PCB technology (2 layers, 1.6mm, std via & clearance) => low cost
Its performance is quasi-insensitive to dielectric thickness => minimal design effort to transfer to other PCB
technologies (thickness, # of layers, etc...)
