LFCG-2850+

Overview

The LFCG-2850+ is a surface-mount LTCC low-pass filter manufactured by Mini-Circuits. It features an 8-pad SMD package (2x1.2mm) with a 50Ω impedance. The device provides a cutoff frequency of 3.25GHz and a typical passband insertion loss of 1.8dB. It supports up to 4.5W RF input power and operates within a temperature range of -55°C to 125°C.

Feature Summary

• Utilizes LTCC technology for compact surface-mount integration
• Provides high rejection characteristics in the stopband
• Supports high RF input power handling capabilities

Applications

• RF signal conditioning circuits
• Microwave communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific suffix (+) indicates RoHS compliance when sourcing. Confirm the package type matches the design footprint requirements. Ensure the operating environment stays within the specified temperature limits. Check for availability of evaluation boards if prototyping is required.

Selection Notes

Select this component for applications requiring a low-profile surface-mount solution. Consider the 3.25GHz cutoff frequency against system bandwidth needs. Evaluate the 1.8dB insertion loss impact on overall link budget. Verify compatibility with standard PCB assembly processes for 8-pad SMD packages.

Part Context

This part belongs to Mini-Circuits' VLF/LFCG series of low-pass filters. These components are designed for RF and microwave applications from DC to several GHz. The series offers various package options including through-hole and surface-mount configurations to suit different manufacturing constraints.

Replacement Considerations

The VLF-2850+ is a through-hole alternative with similar electrical specifications but a different physical package. Cross-referencing requires verifying package dimensions and mounting style compatibility.
