LFCG-2750+

Overview

The LFCG-2750+ is a miniature low-pass filter manufactured by Mini-Circuits, utilizing low temperature co-fired ceramic (LTCC) technology. It operates within a frequency range of DC to 2750 MHz and features a 50 Ohm impedance. The component is designed for surface mount technology (SMT) applications, specifically in an 0805 package size measuring 2.00mm x 1.25mm. It supports high power handling up to 36 dBm and complies with RoHS and REACH standards. The filter provides significant rejection capabilities, offering attenuation levels up to 50dB.

Feature Summary

• Utilizes LTCC construction for compact miniature form factor
• Provides high power handling capability suitable for demanding RF environments
• Delivers substantial out-of-band rejection performance

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in microwave circuits
• Interference filtering in wireless infrastructure

Procurement Notes

Verify the specific ordering suffix and packaging configuration required for your production line, such as cut tape or reel options. Confirm that the LTCC material properties align with your thermal management requirements. Ensure the 0805 footprint matches your PCB design constraints. Check compliance documentation for RoHS and REACH adherence if mandated by your regional regulations. Validate the 36 dBm power rating against your system's maximum input levels to prevent component damage.

Selection Notes

Select this component when a compact low-pass filter is needed for frequencies up to 2.75 GHz. Consider the 0805 SMT package for space-constrained designs requiring surface mounting. Evaluate the 50 Ohm impedance match for standard RF systems. Assess the need for high power handling and significant rejection characteristics. Compare against other LFC series models if different frequency cutoffs or package sizes are required.

Part Context

This part belongs to the LFC series of low-pass filters from Mini-Circuits, which are known for their small size and robust performance. The LFCG variant specifically denotes the use of LTCC technology, offering improved reliability and thermal stability compared to traditional substrates. It is part of a broader family of RF components designed for applications ranging from DC to several gigahertz, providing engineers with standardized solutions for signal integrity.

Replacement Considerations

Direct substitutes may include other Mini-Circuits LFCG series filters with similar cutoff frequencies. Verify compatibility with alternative suppliers' LTCC low-pass filters in the 0805 package. Ensure any replacement maintains the 50 Ohm impedance and comparable rejection specs.
