B.4 JN5148 Module Reference Designs
For customers wishing to integrate the JN5148 device directly into their system, NXP provide a range of Module
Reference Designs, covering standard and high-power modules fitted with different Antennae
To ensure the correct performance, it is strongly recommended that where possible the design details provided by the
reference designs, are used in their exact form for all end designs, this includes component values, pad dimensions,
track layouts etc. In order to minimise all risks, it is recommended that the entire layout of the appropriate reference
module, if possible, be replicated in the end design.
For full details, consult the Standard Module Reference Design JN-RD-6015 [6].
B.4.1 Schematic Diagram
A schematic diagram of the JN5148 PCB antenna reference module is shown in Figure 60. Details of component
values and PCB layout constraints can be found in Table 8.
