Typical Connection Diagrams
5.2 RF Matching Networks
Typical RF matching network circuit diagrams are shown in Figure 5.4 Typical 2.4 GHz RF impedance-matching network circuits on
page 100 for applications in the 2.4GHz band, and in Figure 5.5 Typical Sub-GHz RF impedance-matching network circuits on page
101 for applications in the sub-GHz band. Application-specific component values can be found in the EFR32 Reference Manual. For
low RF transmit power applications less than 13dBm, the two-element match is recommended. For OPNs supporting high power RF
transmission, the four-element match is recommended for high RF transmit power (> 13dBm).
