LFCG-1525+

Overview

The LFCG-1525+ is an LTCC low-pass filter from Mini-Circuits with a passband from DC to 1525 MHz. It operates at a characteristic impedance of 50Ω and utilizes the GE0805C-2 case style. The component is RoHS3 compliant and designed for RF applications requiring harmonic rejection and signal filtering in VHF/UHF systems.

Feature Summary

• LTCC construction for compact form factor
• DC to 1525 MHz passband
• 50Ω impedance matching

Applications

• Harmonic rejection
• Automatic meter reading
• VHF/UHF transmitters

Procurement Notes

Verify the datasheet version and RoHS3 compliance status directly with Mini-Circuits or authorized distributors before procurement. Confirm that the GE0805C-2 package dimensions match your PCB layout requirements. Ensure the 50Ω impedance specification aligns with your system design to prevent signal reflection issues.

Selection Notes

Select this component when a low-pass filter with a cutoff near 1525 MHz is required. The LTCC technology offers stability in various environments. Consider the GE0805C-2 footprint for space-constrained designs. Verify insertion loss and stopband attenuation specifications against specific application needs using official S-parameter data.

Part Context

This part belongs to the LFCG series of ceramic low-pass filters manufactured by Mini-Circuits. The series is designed for RF, IF, and microwave applications up to 86GHz. The LFCG-1525+ specifically targets frequencies up to 1525 MHz, providing a solution for filtering higher frequency harmonics in communication systems.

Replacement Considerations

Consult Mini-Circuits documentation for direct substitutes within the LFCG series. Verify that any alternative maintains the 50Ω impedance and similar cutoff characteristics. Cross-reference package dimensions to ensure mechanical compatibility without redesigning the PCB.
