BFCN-1052+

Overview

The BFCN-1052+ is a surface-mount LTCC bandpass filter designed for RF and microwave applications. It operates within a passband of 9700 MHz to 11950 MHz, providing a bandwidth of 2.25 GHz. The component features a 50 Ohm impedance and utilizes an FV1206-9 case style with SMD-4P packaging measuring 3.20mm x 1.6 mm. Constructed using multilayer ceramic technology, it offers low insertion loss and high rejection at band-reject edges. Wrap-around terminations minimize performance variations due to parasitics, ensuring ruggedness in high humidity and temperature extremes.

Feature Summary

• Multilayer LTCC construction provides a miniature size and high repeatability of performance.
• Wrap-around terminations minimize variations in performance caused by parasitics.
• Rugged package suitable for tough environments including high humidity and temperature extremes.

Applications

• RF/Microwave signal conditioning
• High layout density circuit boards
• Harsh environment electronic systems

Procurement Notes

Verify the specific datasheet version and parameter graphs directly from Mini-Circuits or authorized distributors before finalizing designs. Confirm that the FV1206-9 package dimensions align with your PCB footprint requirements. Ensure environmental specifications meet operational needs regarding humidity and temperature ranges. Cross-reference impedance values to guarantee compatibility with existing 50 Ohm system architectures.

Selection Notes

Select this component when a compact bandpass filter is required for frequencies between 9.7 GHz and 11.95 GHz. The LTCC technology ensures stability in varying environmental conditions compared to other filter types. Consider the small form factor for applications where board space is limited. Verify that the 2.25 GHz bandwidth meets the specific signal processing requirements of the target application.
