摘要

We have analyzed the impact of presence or absence of multiple sized protective shields (aluminum material Faraday cap), where the aluminum material encapsulates the radio frequency (RF) Bluetooth low energy (BLE) device. We have shown the analysis for electromagnetic (EM) compatibility, power-up voltage (V), power-up current (I) and power dissipation ‘ \(\:{P}_{dis}\) = W/m3’ at multiprotocol functions of commercially available system on chip (SOC) BLE with model number (nRF52832). These multiprotocol pin functions of BLE are ((SOC power (PWR) Enable), SOC serial clock (SCL), SOC serial data (SDA), SOC general purpose input / output (GPIO) and SOC Reset). Our effort has shown that how the multiprotocol functions of SOC exhibited (VI-characteristic curve variations) in the power-up conditions, when tested with or without multiple sized aluminum caps. Our comparative study can furnish the handy information to cop up with electromagnetic compatibility (EMC) problems and can meetup with the EMC requirements, when utilizing aluminum cap with (nRF52832) SOC BLE for several prototype designs.
