LFCG-900+

Overview

The LFCG-900+ is an LTCC low pass filter designed for RF applications with a passband from DC to 850 MHz. It features a 50Ω impedance and operates in a compact 0805 (2012 Metric) surface-mount package. The component exhibits a maximum insertion loss of 2.2 dB and maintains a height of 0.95 mm. This filter supports various wireless applications requiring precise frequency control.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for robust construction
• Provides effective signal filtering up to 850 MHz cutoff frequency
• Designed for high-performance radio frequency circuit integration

Applications

• RF wireless systems
• General RF filtering applications
• Microwave component circuits

Procurement Notes

Verify the specific datasheet version when ordering, as some sources cite a 900 MHz limit while official Mini-Circuits documentation specifies 850 MHz. Confirm the package style GE0805C-2 matches your PCB layout requirements. Ensure compatibility with the TB-LFCG-900+ evaluation board if testing is required prior to full deployment.

Selection Notes

Select this component for designs requiring a compact 0805 footprint with reliable LTCC performance. Consider the 2.2 dB insertion loss specification for power budget calculations. The 50Ω impedance makes it suitable for standard RF transmission lines. Evaluate the 850 MHz cutoff against your specific signal bandwidth needs to ensure adequate attenuation of higher frequencies.
