10 dBm Radio Board
BRD4175A Reference Manual
The BRD4175A Mighty Gecko Radio Board enables developers to develop Zigbee,
®
Thread, Bluetooth Low Energy and proprietary wireless applications. The board con-
tains a dual-band Mighty Gecko Wireless System-on-Chip and it is optimized for operat-
ing at 10 dBm output power. For the 2.4 GHz band with the on-board printed antenna
and UFL connector, radiated and conducted testing is supported. For the 169.4 MHz
band, the on-board SMA connector enables conducted testing and attachment of exter-
nal whip antenna for radiated tests.
The BRD4175A Mighty Gecko Radio Board plugs into the Wireless Starter Kit Main-
board, which is included with the Mighty Gecko Starter Kit and gives access to display,
buttons, and additional features from Expansion Boards. With the supporting Simplicity
Studio suite of tools, developers can take advantage of graphical wireless application
development, mesh networking debug and packet trace, and visual energy profiling and
optimization. The board also serves as an RF reference design for applications targeting
2.4 GHz and 434 MHz dual band wireless operation with 10 dBm output power.
This document contains a brief introduction and description of the BRD4175A Radio
Board features, focusing on the RF sections and performance.
