LFCG-612+

Overview

The Mini-Circuits LFCG-612+ is a miniature low-pass filter constructed using low temperature co-fired ceramic (LTCC) technology. It features a center frequency of 5.5 GHz and a bandwidth of 1.2 GHz, with an insertion loss of 1.2 dB. Designed for surface mount applications, it utilizes a 0805 (2012 Metric) package measuring 2.01mm x 1.25mm x 0.68mm. The component operates at a system impedance of 50Ω and is compliant with RoHS3 standards.

Feature Summary

• Utilizes low temperature co-fired ceramic (LTCC) construction for compact form factor
• Provides low-pass filtering characteristics to suppress high-frequency interference
• Designed for surface mount installation in space-constrained RF circuits

Applications

• Base station signal conditioning
• Terminal equipment interference suppression
• Millimeter wave band signal processing

Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation to confirm electrical parameters such as insertion loss and cutoff frequencies. Ensure the LTCC material properties align with the thermal requirements of the target assembly process. Confirm RoHS3 compliance status if required by regional regulations before finalizing procurement orders.

Selection Notes

Select this component when a compact low-pass filter is needed for RF applications around the 5.5 GHz range. The 0805 footprint suits designs requiring minimal board space. Consider the 1.2 dB insertion loss impact on signal chain budget. Verify that the LTCC construction meets the environmental and thermal specifications of the intended operating environment.
