LFCV-1852+

Overview

The LFCV-1852+ is a miniature low temperature co-fired ceramic (LTCC) low pass filter manufactured by Mini-Circuits. It provides a DC to 18.5 GHz passband with a cutoff frequency of 20.25 GHz. The device operates at a standard 50Ω impedance and utilizes an SMT package identified as JV1210C-13. Stopband rejection ranges from 40dB to 50dB across frequencies of 23.7 to 50 GHz, supporting power handling between 0.5W and 8W.

Feature Summary

• Utilizes LTCC technology for compact surface-mount integration
• Provides high stopband rejection up to 50 GHz
• Supports moderate power handling capabilities

Applications

• RF signal conditioning in microwave systems
• Harmonic suppression in transmitter chains
• Interference filtering in wireless communication links

Procurement Notes

Verify the specific datasheet version for precise insertion loss and VSWR values at your operating frequency. Confirm that the JV1210C-13 footprint matches your PCB layout requirements. Ensure thermal management aligns with the specified power handling limits during continuous operation.

Selection Notes

Select this component when a sharp cutoff near 20 GHz is required within a small form factor. Consider the LTCC construction for stability in varying environmental conditions. Evaluate the 40-50 dB stopband attenuation against system noise floor requirements to ensure adequate interference rejection.

Part Context

This part belongs to the LFCV series of LTCC low pass filters from Mini-Circuits. These components are designed for applications requiring reliable signal filtering in compact RF circuits. The series offers various cutoff frequencies to suit different bandwidth needs while maintaining consistent 50Ω performance.

Replacement Considerations

Consult official Mini-Circuits substitution guides for compatible alternatives. Verify that any substitute maintains the same DC to 18.5 GHz passband and 50Ω impedance characteristics.
