BFCN-8450+

Overview

The BFCN-8450+ is a surface-mount LTCC bandpass filter designed for RF applications. It operates with a center frequency of 8450 MHz and provides a bandwidth of 200 MHz, covering the range from 8350 to 8550 MHz. The component features a 50 Ohm impedance and utilizes an FV1206-4 package style. Key electrical specifications include a maximum insertion loss of 3.5 dB. The device is RoHS compliant and supports tape and reel packaging.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for compact surface-mount integration
• Provides precise signal selection within the S-band frequency range
• Designed for high isolation performance in dense circuit layouts

Applications

• S-band upconverter assemblies
• Satellite communication systems
• Space qualified RF filtering

Procurement Notes

Verify the specific datasheet version for the BFCN-8450+ to confirm exact electrical tolerances and mechanical dimensions before finalizing design integration. Ensure that the FV1206-4 footprint matches the target PCB layout requirements. Confirm compliance with relevant environmental standards such as RoHS if required by the end application. Cross-reference official Mini-Circuits documentation for any updates regarding lead-free soldering profiles or handling instructions.

Selection Notes

Select this component when a narrow 200 MHz bandwidth is required at 8.45 GHz with low insertion loss constraints. The LTCC construction offers stability suitable for demanding environments. Consider the FV1206-4 package size for space-constrained designs. Evaluate the stopband rejection characteristics against system interference requirements to ensure adequate signal purity.
