LFCG-360+

Overview

The LFCG-360+ is a miniature low temperature co-fired ceramic (LTCC) low pass filter manufactured by Mini-Circuits. It provides a DC to 360 MHz passband with a 50Ω impedance. Typical electrical parameters include an insertion loss of 0.9 dB, stop band rejection of 46 dB, and pass band return loss of 19 dB. The device supports stopband frequencies at 630 to 830 MHz, 830 to 1500 MHz, and 1500 to 3000 MHz.

Feature Summary

• Utilizes low temperature co-fired ceramic (LTCC) technology for compact SMD packaging
• Provides effective suppression of high-frequency harmonics and RF clutter
• Ensures stable performance with low temperature drift characteristics

Applications

• Multi-band RF filtering designs in wireless devices
• RF test equipment signal conditioning
• Industrial measurement and control systems

Procurement Notes

Verify the specific datasheet version and ordering suffix when sourcing. Confirm that the LTCC package dimensions match the target PCB footprint. Ensure the operating environment remains within the specified thermal limits to maintain the documented typical parameter stability. Cross-reference the manufacturer's official documentation for any recent design changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component for applications requiring a sharp cutoff near 360 MHz with minimal size constraints. The LTCC construction offers superior thermal stability compared to standard ceramic alternatives. Evaluate the 0.9 dB insertion loss against system link budget requirements. Consider the 46 dB stopband rejection for harmonic suppression needs in the 630 MHz to 3 GHz range.

Part Context

This part belongs to the LFCG series of LTCC low pass filters from Mini-Circuits. The series is designed for general-purpose RF filtering where compact size and reliable performance are critical. It complements other passive components like power dividers and baluns in complete RF front-end designs.

Replacement Considerations

Consult Mini-Circuits official substitution guides for equivalent LTCC low pass filters with similar cutoff frequencies. Verify pin compatibility and impedance matching when considering alternative manufacturers.
