LFCW-6500+

Overview

The LFCW-6500+ is a low-pass filter manufactured by Mini-Circuits, utilizing LTCC technology. It features a passband from DC to 6.5 GHz and operates at a nominal impedance of 50 Ohms. The component is housed in a surface-mount 0603 (1608 Metric) package with four pads. Electrical specifications include an insertion loss of 2.5 dB and a cutoff frequency of 7.5 GHz.

Feature Summary

• Utilizes LTCC construction for compact surface-mount integration
• Provides low-pass filtering functionality within RF and microwave circuits
• Designed for standard 50 Ohm system impedance matching

Applications

• RF signal conditioning
• Microwave circuit design
• Harmonic suppression

Procurement Notes

Verify the specific datasheet version and electrical characteristics against the manufacturer's official documentation before procurement. Confirm that the 0603 package dimensions and pad layout align with your PCB design requirements. Ensure the operating temperature range meets your application needs. Cross-reference the part number suffix to confirm availability of evaluation boards or specific testing data if required for validation.

Selection Notes

Select this component when a low-pass filter with a 6.5 GHz passband is required in a space-constrained environment. The 0603 footprint suits high-density board layouts. Consider the 2.5 dB insertion loss impact on system gain. Verify compatibility with 50 Ohm transmission lines. Evaluate thermal performance if operating near maximum ratings.

Part Context

This component belongs to Mini-Circuits' LFCW series of ceramic filters. These parts are designed for RF and IF applications up to 86 GHz. The LFCW-6500+ specifically targets frequencies below 6.5 GHz. It shares the LTCC manufacturing process with other models in the lineup, ensuring consistent quality and reliability across the product family.

Replacement Considerations

The LFCW-7500+ offers a similar form factor but with a higher cutoff frequency of 7.5 GHz. Verify if the extended bandwidth affects system performance. No direct equivalent substitutes are documented in the provided source material.
