LFCG-400+

Overview

The LFCG-400+ is a low temperature co-fired ceramic (LTCC) low pass filter manufactured by Mini-Circuits. It provides a DC to 400 MHz passband with a 50Ω impedance. The component operates within a temperature range of -40°C to +85°C and features an insertion loss of 1.8dB. The cutoff frequency is specified at 520MHz. It utilizes an SMD-8P package in a 0805 (2x1.2mm) case style.

Feature Summary

• Utilizes LTCC technology for compact surface mount integration
• Provides harmonic rejection capabilities
• Designed for VHF/UHF transmitter applications

Applications

• Harmonic rejection
• Automatic meter reading
• VHF/UHF transmitters

Procurement Notes

Verify the specific ordering suffix against official Mini-Circuits documentation to ensure correct packaging configuration, such as reel options. Confirm that the selected variant matches the required operating temperature range and physical dimensions for your PCB layout. Cross-reference the datasheet specifications to validate performance parameters before procurement.

Selection Notes

Select this component when a DC to 400 MHz low pass response is required in a miniature form factor. The LTCC construction supports high reliability in harsh environments. Ensure the 50Ω system impedance aligns with your circuit design. Consider the 0805 footprint constraints during the layout phase to accommodate the SMD-8P package.
