BFHK-2492+

Overview

The BFHK-2492+ is a surface-mountable LTCC bandpass filter designed for high-frequency applications. It operates within a passband of 22,000 to 28,000 MHz with a center frequency of 24.9 GHz. The component features a 50Ω impedance and utilizes a proprietary LTCC material system to ensure miniature size and high performance repeatability. Packaged in an NM1812C-3 case style (LGA-3, 4.5x3.2 mm), it supports automated assembly processes.

Feature Summary

• Utilizes proprietary Low-Temperature Co-fired Ceramic (LTCC) technology for compact form factor
• Designed for very high volume automated assembly processes
• Provides high repeatability of RF performance characteristics

Applications

• Microwave communication systems operating in the K-band
• High-frequency radio frequency front-end modules
• Satellite communication equipment requiring precise filtering

Procurement Notes

Verify the specific ordering suffix and package variant against the official Mini-Circuits datasheet before procurement. Ensure compatibility with standard SMT reflow profiles. Confirm that the required evaluation board, such as TB-BFHK-2492C+, is available if testing is needed prior to integration. Cross-reference pinout diagrams with PCB layout requirements.

Selection Notes

Select this component when a fixed 22–28 GHz passband is required for microwave applications. The LTCC construction offers stability compared to other filter types. Consider the NM1812C-3 footprint constraints during PCB design. Evaluate insertion loss specifications against system link budget requirements. Ensure the 50Ω impedance matches the surrounding circuitry.

Part Context

This part belongs to the BFHK series of LTCC bandpass filters from Mini-Circuits. These components are engineered for RF, IF, and microwave frequencies up to 86 GHz. The series emphasizes miniaturization and reliability for modern electronic designs. The BFHK-2492+ specifically targets the 24.9 GHz center frequency range.
