LFCW-8000+

Overview

The LFCW-8000+ is an LTCC low-pass filter manufactured by Mini-Circuits. It features a cutoff frequency of 8.9 GHz and operates with a 50 Ohm impedance. The component exhibits an insertion loss of 2.3 dB. It utilizes a surface-mount 0603 (1608 Metric) package with four PCB pads. Physical dimensions are 1.60mm length, 0.80mm width, and a maximum height of 0.60mm. The device complies with RoHS3 standards.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for robust signal conditioning
• Provides high attenuation in the stopband to suppress unwanted frequencies
• Designed for surface-mount integration into compact RF circuits

Applications

• RF communication systems requiring DC to 8 GHz passband filtering
• Signal conditioning in microwave components
• Interstage filtering in RF front-end modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm packaging type, such as tape and reel or cut tape. Confirm that the component status remains active before finalizing procurement plans. Ensure compatibility with standard SMT assembly processes for 0603 footprints. Check for any updated environmental compliance certifications required by your region.

Selection Notes

Select this component when a sharp cutoff near 8.9 GHz is required within a minimal footprint. The 50 Ohm impedance matches standard RF transmission lines. Consider the 2.3 dB insertion loss impact on system noise figure. The LTCC construction offers stability suitable for various operating environments compared to discrete LC solutions.

Part Context

This part belongs to the LFCW series of ceramic filters from Mini-Circuits. These components are designed for general-purpose RF applications. The series emphasizes small size and high performance. The LFCW-8000+ specifically targets applications needing low-pass characteristics up to the 8 GHz range.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternatives. Cross-reference specifications such as cutoff frequency, insertion loss, and package dimensions. Ensure any substitute maintains the 50 Ohm impedance and LTCC construction if thermal stability is critical.
