BFTC-500+

Overview

The BFTC-500+ is a 50Ω LTCC bandpass filter with a 400 to 600 MHz passband. It features a center frequency of 500MHz, 200MHz bandwidth, and 5.5dB insertion loss. The component provides 25dB upper/lower stopband rejection and handles up to 4W RF input power. It utilizes a 6-SMD, No Lead package (Case Style FR933-1) and offers typical 1.5 VSWR.

Feature Summary

• Low temperature co-fired ceramic (LTCC) construction for compact integration
• High power handling capability up to 4W RF input
• Symmetric upper and lower stopband rejection characteristics
• Surface-mount design suitable for automated assembly

Applications

• RF front-end filtering in communication systems
• Interstage filtering in multi-stage amplifier chains
• Signal conditioning in test and measurement equipment

Procurement Notes

Verify the specific ordering suffix and tape-and-reel configuration against the manufacturer's current datasheet. Confirm that the 4W power rating aligns with your thermal management requirements. Ensure the 6-SMD footprint matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a 400-600 MHz passband is required with high power tolerance. The LTCC technology ensures stability across temperature variations. Compare insertion loss and VSWR specifications against system link budget requirements to ensure signal integrity is maintained within acceptable limits.

Part Context

This part belongs to Mini-Circuits' BFTC series of LTCC bandpass filters. These components are designed for RF and IF applications, offering a balance between performance and size. The series covers various frequency ranges, with the BFTC-500+ specifically targeting the UHF band for robust signal processing tasks.

Replacement Considerations

Check for direct substitutes within the BFTC series or other Mini-Circuits LTCC filters with identical 400-600 MHz specifications. Verify pin compatibility and thermal characteristics if replacing with components from other manufacturers.
