LFCV-2002+

Overview

The LFCV-2002+ is a miniature low-temperature co-fired ceramic (LTCC) low pass filter manufactured by Mini-Circuits. It features a DC to 20 GHz passband and operates with a 50 Ohm impedance. The device utilizes surface mount technology in a 1210 package. Typical performance specifications include an insertion loss of 1.6 dB, a return loss of 12 dB, and stop band rejection of 35 dB.

Feature Summary

• Constructed using low-temperature co-fired ceramic (LTCC) technology for compact form factor
• Designed for surface mount integration into RF circuits
• Provides signal conditioning through low pass filtering characteristics

Applications

• RF signal path filtering
• Harmonic suppression in communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet version when sourcing, as performance curves may vary slightly between revisions. Confirm that the 1210 package dimensions align with your PCB footprint requirements. Ensure compatibility with standard reflow soldering profiles used for LTCC components. Check for any specific handling instructions regarding electrostatic discharge protection during assembly.

Selection Notes

Select this component when a wide bandwidth up to 20 GHz is required in a small surface mount package. Consider the typical insertion loss and stop band rejection values against system noise floor and interference requirements. Evaluate the physical size constraints of the design against the 1210 metric footprint. Ensure the operating frequency range matches the intended application spectrum needs.

Part Context

This part belongs to the LFCV series of LTCC low pass filters from Mini-Circuits. The series offers various cutoff frequencies while maintaining consistent packaging and construction methods. These filters are designed for high-reliability applications requiring stable performance across temperature variations. The LFCV-2002+ specifically targets higher frequency operations compared to lower cutoff variants in the same family.

Replacement Considerations

Direct substitutes within the LFCV series include models with similar cutoff frequencies, such as the LFCV-2802+. Verify electrical parameters match before substitution. Alternative manufacturers may offer comparable LTCC filters but require full parameter validation.
