Application note
BAL-NRF02D3 matched balun with integrated harmonics filter for
Nordic Semiconductor chips with ultralow power transceivers
Introduction
The nRF51422-CEAA and nRF51822-CEAA from Nordic Semiconductor are 2.45 GHz
combo chips with an ultralow power transceiver.
The BAL-NRF02D3 from STMicroelectronics is an ultraminiature balun for which the
matching impedance has been customized for the nRF51422-CEAA, and nRF51822-CEAA
Nordic Semiconductor circuits.
The BAL-NRF02D3 integrates matching network and harmonics filters. It uses
STMicroelectronics’ IPD technology on non-conductive glass substrate which optimizes RF
performance.
The BAL-NRF02D3 has been tested and approved by Nordic Semiconductor on the
PCA10018 nRFgo module.The BAL-NRF02D3 demonstrates a higher system performance
compared to traditional solutions. This document presents the test and performance results.
