BFCV-2895+

Overview

The BFCV-2895+ is an LTCC bandpass filter designed for surface mount applications. It operates at a center frequency of 2.895 GHz with a 50 Ohm impedance. The component utilizes a 4-SMD, No Lead package configuration to ensure compact integration. Key electrical specifications include an insertion loss of 4 dB and a wide rejection bandwidth ranging from 2222 MHz to 3570 MHz. It supports operation within a temperature range of -55°C to +100°C.

Feature Summary

• Constructed using Low Temperature Co-fired Ceramic (LTCC) technology for high performance repeatability
• Features wrap-around electrodes to minimize size while maintaining signal integrity
• Provides very good wide band rejection characteristics alongside low insertion loss

Applications

• RF front-end filtering in wireless communication systems
• EMI/RFI suppression in microwave circuits
• Signal conditioning in cellular infrastructure modules

Procurement Notes

Verify the specific datasheet version corresponding to the BFCV-2895+ part number before procurement. Confirm that the required center frequency and bandwidth align with system design parameters. Ensure compatibility with standard SMT reflow processes given the no-lead package type. Check for any recent product change notices regarding material or dimensional updates.

Selection Notes

Select this component when a miniature form factor is critical for board layout density. The LTCC construction offers superior thermal stability compared to other filter types. Consider the 4 dB insertion loss against system link budget requirements. The wide rejection bandwidth makes it suitable for environments requiring significant out-of-band noise suppression.

Part Context

This component belongs to Mini-Circuits' BFCV series of LTCC bandpass filters. The series is characterized by its use of multi-layer ceramic technology to achieve small physical dimensions. These filters are engineered for high repeatability and are commonly used in RF applications where space constraints are severe.

Replacement Considerations

Direct substitutes may include other Mini-Circuits LTCC bandpass filters with similar center frequencies and package footprints. Verify mechanical dimensions and pinout compatibility before substitution. Cross-reference electrical specifications such as insertion loss and rejection bandwidth to ensure equivalent performance.
