FRDM-KW41Z RF System Evaluation Report
for 802.15.4 Applications
1. Introduction
This document provides the RF evaluation test results
of FRDM-KW41Z for the 802.15.4 applications
(O-QPSK modulation). It includes the test setup
description and the tools for you to perform the tests on
your own. To get the KW41Z radio parameters, see the
MKW41Z/31Z/21Z Data Sheet (document
MKW41Z512).
