BFCN-1575+

Overview

The BFCN-1575+ is a surface-mount LTCC bandpass filter designed for signal conditioning applications. It features a center frequency of 1.575 GHz with a bandwidth of 90 MHz and operates at an impedance of 50 Ohms. The component utilizes multilayer ceramic technology to achieve a miniature form factor, specifically in a 4-SMD, No Lead package. This construction ensures high repeatability and ruggedness suitable for tough environments, including high humidity and temperature extremes. The design incorporates wrap-around terminations to minimize performance variations caused by parasitics.

Feature Summary

• Constructed using Low-Temperature Co-fired Ceramic (LTCC) technology for a compact size and high structural integrity.
• Features wrap-around terminations to reduce performance variations resulting from parasitic effects.
• Provides low insertion loss and effective rejection characteristics at the band-reject edges.
• Offers a rugged package capable of withstanding high humidity and extreme temperature conditions.

Applications

• Signal conditioning in RF circuits
• S-band upconverter assemblies
• Electronic devices requiring frequency filtering
