LFCG-1900+

Overview

The LFCG-1900+ is a miniature low temperature co-fired ceramic (LTCC) low pass filter manufactured by Mini-Circuits. It features a DC to 1.9 GHz passband and a cutoff frequency of 2.3 GHz. The component operates at a system impedance of 50 Ohms and supports a maximum power handling of 37 dBm. It utilizes an SMT termination method and is housed in an 0805 (2012 Metric) package with 8 PC pads. The device exhibits an insertion loss of 1.8 dB within the passband.

Feature Summary

• Constructed using low temperature co-fired ceramic (LTCC) technology for compact form factor
• Provides effective signal filtering with a defined DC to 1.9 GHz passband
• Designed for surface mount integration via 0805 package configuration

Applications

• RF signal conditioning in communication systems
• Frequency selection in radio frequency circuits
• Harmonic suppression in RF front ends

Procurement Notes

Verify the specific datasheet version and compliance documentation, such as RoHS and REACH status, directly from Mini-Circuits or authorized distributors before procurement. Confirm that the 0805 footprint matches your PCB design constraints. Ensure that the 37 dBm power rating aligns with your system's operational requirements to prevent component damage. Cross-reference the 50 Ohm impedance specification with your circuit design parameters.

Selection Notes

Select this component when a compact LTCC low pass filter is required for applications operating up to 1.9 GHz. The 0805 package size suits space-constrained designs. Consider the 1.8 dB insertion loss and 2.3 GHz cutoff frequency relative to your specific frequency response needs. Verify compatibility with standard SMT assembly processes due to the surface mount termination style.

Part Context

This part belongs to Mini-Circuits' LFCG series of LTCC filters. These components are designed for high performance in RF and IF applications. The series offers various cutoff frequencies while maintaining small footprints suitable for modern electronic devices. The LFCG-1900+ specifically targets applications requiring filtering below 2.3 GHz.
