LFCG-1575+

Overview

The Mini-Circuits LFCG-1575+ is a low-pass filter utilizing Low Temperature Co-fired Ceramic (LTCC) technology. It provides a passband from DC to 1575 MHz with a characteristic impedance of 50Ω. The component features an insertion loss of 1.8dB and operates within the 0805 surface-mount package, measuring 2.00mm x 1.25mm.

Feature Summary

• Constructs signal filtering using LTCC technology for compact integration
• Provides low insertion loss characteristics for efficient signal transmission
• Designed for surface-mount assembly in standard 0805 footprints

Applications

• RF signal conditioning circuits
• Microwave frequency filtering applications
• Evaluation board testing setups

Procurement Notes

Verify the specific datasheet version before procurement, as product change notifications may alter specifications. Confirm the package type matches the PCB layout requirements. Ensure the ordering suffix corresponds to the desired tape and reel configuration. Cross-reference the manufacturer's official documentation for any recent environmental rating updates or pinout modifications.

Selection Notes

Select this component when a DC to 1575 MHz cutoff is required in a minimal footprint. The 50Ω impedance aligns with standard RF systems. Consider the 0805 size for space-constrained designs. Evaluate the 1.8dB insertion loss against system power budgets. Verify compatibility with LTCC manufacturing processes if customizing substrates.
