LFCV-1450+

Overview

The LFCV-1450+ is a low-pass filter manufactured by Mini-Circuits, designed for signal conditioning applications. It features a passband from DC to 1450 MHz and operates with a characteristic impedance of 50Ω. The component utilizes LTCC technology and is housed in a JV1210C surface-mount package. Official documentation indicates a cutoff frequency of 1500 MHz, distinguishing it from similar models like the LFCN-1450+. The device provides stopband rejection ranging from 40dB to 50dB.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for compact surface-mount integration
• Provides high stopband rejection within the specified range
• Designed for precise signal filtering with a defined cutoff frequency

Applications

• RF signal conditioning circuits
• S-band upconverter assemblies
• General-purpose low-pass filtering in microwave systems

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update specifications or pin configurations over time. Confirm that the required cutoff frequency of 1500 MHz aligns with your design needs, particularly if comparing against the LFCN-1450+ variant which exhibits different cutoff characteristics. Ensure compatibility with the JV1210C footprint during PCB layout planning.

Selection Notes

Select this component when a sharp cutoff at 1500 MHz is required for DC to 1450 MHz signals. Consider the LTCC construction for reliability in surface-mount applications. Evaluate the 40dB to 50dB stopband rejection against system noise requirements. Compare physical dimensions of the JV1210C case style against available board space constraints before finalizing the design.

Part Context

This part belongs to the LFCV series of LTCC low-pass filters from Mini-Circuits. These components are engineered for RF and microwave environments requiring stable performance. The series offers various cutoff frequencies, with the LFCV-1450+ specifically targeting applications needing attenuation above 1500 MHz while maintaining signal integrity below 1450 MHz.

Replacement Considerations

The LFCN-1450+ is a related model but cuts off at 1825 MHz rather than 1500 MHz. Substitution requires verifying that the higher cutoff frequency does not compromise stopband requirements. No other direct substitutes are confirmed in public documentation.
