LFCG-4400+

Overview

The Mini-Circuits LFCG-4400+ is an LTCC low pass filter with a passband from DC to 4400 MHz. It provides 1.6 dB insertion loss and operates at 50 Ohms impedance. The component supports SMD/SMT termination and functions within a temperature range of -55°C to +125°C.

Feature Summary

• LTCC construction for compact surface mount integration
• Low insertion loss performance in the passband
• Wide operating temperature range for harsh environments

Applications

• RF signal filtering in communication systems
• Harmonic suppression in transmitter chains
• Interference rejection in receiver front ends

Procurement Notes

Verify the specific datasheet version for exact attenuation curves and power handling limits. Confirm package dimensions match PCB footprint requirements. Ensure thermal management aligns with the specified operating temperature range during system integration.

Selection Notes

Select this component when a low pass filter up to 4.4 GHz is required. Consider the 50 Ohm impedance matching for system compatibility. Evaluate the LTCC technology benefits for size and reliability against other filter types.

Part Context

This part belongs to Mini-Circuits' RF filter portfolio, utilizing Low Temperature Co-fired Ceramic (LTCC) technology. It is designed for high-reliability applications requiring stable performance across wide temperature variations and compact form factors.

Replacement Considerations

Check Mini-Circuits documentation for direct substitutes. Verify electrical parameters such as cutoff frequency and insertion loss before substitution.
