LFCN-1400+

Overview

The LFCN-1400+ is an LTCC low pass filter designed for RF applications up to 1400 MHz. It operates with a 50Ω impedance and features a compact 1206-sized surface-mount package. The component handles 10W of power and maintains a VSWR of 1.2:1. It provides 20 dB rejection at 2015 MHz, ensuring effective signal filtering in high-frequency circuits.

Feature Summary

• LTCC construction for reliable performance
• Compact 1206 surface-mount footprint
• High power handling capability
• Effective out-of-band rejection

Applications

• RF signal conditioning
• Wireless communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific suffix requirements against the official Mini-Circuits datasheet before ordering. Confirm that the standard LFCN-1400+ variant meets your DC isolation needs, as alternative suffixes like 'D' may be required for DC pass-through specifications. Ensure compatibility with your PCB layout constraints regarding the 1206 package size.

Selection Notes

Select this component when a robust ceramic low pass filter is needed for frequencies up to 1400 MHz. Consider the 10W power handling and 1.2:1 VSWR for high-performance RF paths. Evaluate if the standard non-DC-pass version suffices or if a specialized suffix is necessary for your circuit's grounding requirements.

Part Context

Mini-Circuits manufactures a wide range of RF, IF, and microwave components. The LFCN series represents their LTCC low pass filters, which are widely used in wireless communications and industrial control. This model fits within their portfolio of compact, high-reliability passive components designed for demanding environments.

Replacement Considerations

Consult the official datasheet for direct substitutes. Alternative models may include variants with different cutoff frequencies or power ratings. Verify pinout and package compatibility before replacing.
