Bourns FBD1608N080D6 Balanced LTCC Band Pass Filter

Introduction

The Bourns FBD1608N080D6 is a compact balanced LTCC band pass filter designed for sub-GHz wireless designs. It combines RF filtering, impedance matching, and balun functionality in a single passive component, helping simplify RF signal-chain layouts.

Part Description

The FBD1608N080D6 is a balanced band pass filter from Bourns for operation across the 770 MHz to 928 MHz frequency range. Its LTCC construction supports a small footprint while integrating several functions that might otherwise require separate RF components.

By passing the intended sub-GHz band while attenuating unwanted out-of-band signals, the component can help improve receiver selectivity and reduce interference. Its integrated balun and impedance-matching capabilities make it particularly useful where a balanced RF IC interface must connect efficiently to an antenna or single-ended RF path.
