LFCW-1062+

Overview

The Mini-Circuits LFCW-1062+ is a Low Temperature Co-fired Ceramic (LTCC) low pass filter housed in a compact 0603 surface-mount package. It provides DC to 10.6 GHz passband operation with a cutoff frequency of 10.6 GHz. The component exhibits a maximum insertion loss of 0.7 dB and offers high stopband rejection, reaching 20 dB at 12 GHz and 31 dB at 15.21 GHz. Designed for 50 Ohm systems, it integrates multilayer construction to ensure stable performance across wide frequency ranges while maintaining a small physical footprint suitable for dense circuit layouts.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for robust multilayer construction
• Provides effective signal attenuation in the stopband due to strategically designed layout
• Maintains low passband insertion loss for minimal signal degradation
• Housed in a miniature 0603 surface-mount package for space-constrained applications

Applications

• RF front-end filtering in wireless communication systems
• Harmonic suppression in microwave circuits
• Signal conditioning in test and measurement equipment
• Interstage filtering in RF transceivers

Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to confirm exact electrical tolerances and termination specifications. Ensure compatibility with standard reflow soldering profiles for 0603 LTCC components. Cross-reference the part number with authorized distributors to validate authenticity and traceability. Confirm that the operating environment matches the component's thermal and mechanical ratings.

Selection Notes

Select this component when a compact form factor is required alongside moderate insertion loss and significant stopband rejection up to 15 GHz. The 0603 package size makes it suitable for high-density PCB designs where space is limited. Consider the LTCC construction for improved reliability compared to discrete LC implementations. Evaluate the 50 Ohm impedance match against system requirements to ensure optimal power transfer and minimal reflection.

Part Context

The LFCW series from Mini-Circuits represents a line of LTCC ceramic filters designed for high-performance RF applications. These components bridge the gap between bulky traditional filters and less reliable discrete solutions. The LFCW-1062+ specifically targets frequencies up to 10.6 GHz, offering a balance between size, cost, and electrical performance for modern wireless infrastructure and consumer electronics.

Replacement Considerations

Consult Mini-Circuits official substitution guides for direct equivalents. Verify that any alternative maintains the same 0603 footprint and LTCC construction to ensure mechanical compatibility. Check that replacement parts meet or exceed the 0.7 dB insertion loss and 20 dB stopband rejection specifications at 12 GHz.
