Product Introduction

Overview

The BALF-SPI-02D3 is an ultra-miniature balun designed by STMicroelectronics, optimized for use with the SPIRIT1 transceiver. This component integrates a matching network and harmonic filter, specifically tailored for 434 MHz frequency applications. It utilizes STMicroelectronics' IPD (Integrated Passive Device) technology on a non-conductive glass substrate, which enhances RF performance. The balun is characterized by its low insertion loss, low amplitude and phase imbalance, and a very small footprint, making it ideal for compact and high-performance RF designs.
