MCX W71 RF System Evaluation for IEEE 802.15.4 Applications with Interferer Coexistence
RF system evaluation for NXP MCX W71 MCU in IEEE 802.15.4 applications, focusing on coexistence with noise, sinewave, Bluetooth audio, and Wi-Fi interference.
Overview
This application note details the test setup and procedures for evaluating the RF performance of the NXP MCX W71 MCU within IEEE 802.15.4 applications. It specifically addresses coexistence performance when subjected to various interferers including white noise, sinewave (continuous wave), Bluetooth audio, and Wi-Fi signals. The document provides methodologies for measuring carrier-to-noise ratio (C/N), packet error rate (PER), adjacent-channel interference (ACI), and co-channel immunity. Evaluation is conducted using the FRDM-MCXW71 hardware board and professional signal generators to characterize the baseband and demodulator performance of the MCX W71 radio.
Use Cases
- Bench testing RF performance of MCX W71-based wireless designs
- Evaluating wireless device reliability in environments with high Wi-Fi or Bluetooth traffic
- Characterizing OQPSK modulation performance under interference
- Validating receiver immunity and sensitivity for IEEE 802.15.4 applications
