Description

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

harmonics filter.

Matching impedance has been customized for the BLUENRG-134 and BlueNRG-234

WLCSP from STMicroelectronics.

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