Silicon Laboratories EFR32 1 Series Layout Design Manual

AN928.1: EFR32 Series 1 Layout Design
Guide
The purpose of this application note is to help users design PCBs
for the EFR32 Wireless Gecko Portfolio using design practices
that allow for good RF performance.
The 2.4 GHz matching principles are described in the application note,
EFR32 Series 1 2.4GHz Matching
section is discussed in AN923: EFR32 sub-GHz Matching
subjects are detailed in the following application notes:
EFM32GG1x/TG11 Compatibility and Migration
and DC-DC, and AN0955: CRYPTO.
The Silicon Labs MCU and Wireless Starter Kits and Simplicity Studio provide a power-
ful development and debug environment. In order to take advantage of the capabilities
and features on custom hardware, Silicon Labs recommends including debugging and
programming interface connector(s) in custom hardware designs. The details and ben-
efits of including these connector interfaces are detailed in
gramming Interfaces for Custom
The power configurations and the proper usage of the internal DC-DC converter of
EFR32 is described in AN0948: Power Configurations and
ance strongly depends on the PCB layout, as well as the design of the matching net-
works. For optimal performance, Silicon Labs recommends using the PCB layout de-
sign guidelines described in the following sections.
