Sub-1GHz Module Datasheet

Introduction

The ATSAMR30M18A is an IEEE

®

802.15.4

™

-2003/2006/2011-compliant RF module for the sub-1 GHz ISM bands,

such as 780 MHz (China), 868 MHz (Europe) and 915 MHz (North America), optimized for low-power applications.
This module combines the ATSAMR30E18A SiP (System in Package), 16 MHz crystal oscillator, discrete balun,
lumped element harmonic reject filter and required RF shielding in a compact 12.7 mm x 11.0 mm design. The
module as implemented on the Xplained Pro development board has passed regulatory approvals with chip antenna
or SMA connectorized monopole antenna.

This data sheet provides only a brief overview of the necessary sections of the module. For a detailed description of
each peripheral, refer to the
