LFCG-1200+

Overview

The Mini-Circuits LFCG-1200+ is a low pass filter utilizing Low Temperature Co-fired Ceramic (LTCC) technology. It provides a passband from DC to 1200 MHz with a cutoff frequency of 1.47 GHz. The component operates at a system impedance of 50 Ohms and exhibits an insertion loss of 1.8 dB. Its physical dimensions are 2.00 mm in length, 1.25 mm in width, and 0.95 mm in maximum height, corresponding to the GE0805C-2 case style.

Feature Summary

• Constructs signal filtering using LTCC ceramic materials for compact integration
• Provides attenuation above the 1200 MHz passband limit
• Designed for surface mount assembly on printed circuit boards

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter output stages
• Interference filtering in receiver front ends

Procurement Notes

Verify the specific datasheet version and revision history before procurement to ensure compatibility with current design requirements. Confirm that the ordering suffix matches the required termination or packaging specifications. Cross-reference the footprint details with the PCB layout library to prevent assembly errors during manufacturing.

Selection Notes

Select this component when a sharp cutoff near 1.2 GHz is required within a minimal footprint. Evaluate the thermal performance and power handling capabilities against the specific application load. Ensure the 50 Ohm impedance matches the surrounding transmission line characteristics to minimize signal reflection and maintain system integrity.

Part Context

This device belongs to the Mini-Circuits LFCG series of LTCC filters. These components are engineered for high reliability and consistent performance in RF environments. The series offers various cutoff frequencies while maintaining standardized package dimensions for easy replacement and design flexibility across different product lines.

Replacement Considerations

Direct substitutes include other Mini-Circuits LTCC low pass filters with similar cutoff frequencies and package sizes. Verify electrical parameters such as insertion loss and stopband rejection match the original design specifications before implementing any alternative part numbers.
