Rev. 1.00BRD4164A Reference Manual Introduction 1. Introduction The EFR32 Mighty Gecko Radio Boards provide a development platform (together with the Wireless Starter Kit Mainboard) for the Silicon Labs EFR32 Mighty Gecko Wireless System on Chips and serve as reference designs for the matching networks of the RF in- terfaces. The BRD4164A Radio Board supports dual-band operation with its integrated sub-GHz ISM band and 2.4 GHz band transceivers. The sub-GHz section is designed to the operate in the band with an external whip antenna, the 2.4 GHz section is designed to operate at the 2400-2483.5 MHz band with the on-board printed antenna. The matching networks are optimized to 19 dBm output power. To develop and/or evaluate the EFR32 Mighty Gecko the BRD4164A Radio Board can be connected to the Wireless Starter Kit Main- board to get access to display, buttons and additional features from Expansion Boards and also to evaluate the performance of the RF interfaces. silabs.com Smart.
