Description

This device is an ultraminiature extra thin balun that integrates matching network and

harmonics filter.

Matching impedance has been customized for the nRF51822-CTAA and CTAC

WLCSP Nordic Semiconductor circuits.

Based on IPD technology on high resistivity silicium it optimizes the RF performance.

The BALF-NRF01J5 has been tested and approved by Nordic Semiconductor.

STMicroelectronics qualified this product intended to be used in System in Package

module based on standard reliability procedure. For more details, please contact ST

representatives.

It is the responsibility of the customer to perform qualification reliability verifications

as it is related to customer specific application / mission profile and module design /

process.
