LFCN-2600+

Overview

The LFCN-2600+ is an LTCC low-pass filter manufactured by Mini-Circuits, designed for RF and IF applications. It operates from DC to 2600 MHz with a nominal impedance of 50 Ohms. The component utilizes the FV1206 case style and supports surface mount installation via tape and reel packaging. It functions as a signal conditioning element within the LFCG/LFCN series, providing frequency selection capabilities in microwave circuits.

Feature Summary

• Utilizes LTCC technology for compact surface mount integration
• Provides low-pass filtering characteristics from DC to 2600 MHz
• Designed for 50 Ohm system impedance environments

Applications

• RF signal conditioning
• IF stage filtering
• Microwave circuit frequency selection

Procurement Notes

Verify the specific suffix requirements against the official datasheet before ordering. Confirm whether DC isolation or DC pass functionality is needed, as this may require alternative suffixes such as 'D'. Ensure the FV1206 package dimensions align with the target PCB layout constraints. Cross-reference the manufacturer part number with distributor listings to confirm current availability and lead times.

Selection Notes

Select this component when a low-pass response up to 2600 MHz is required in a 50 Ohm system. Consider the FV1206 footprint size relative to available board space. Evaluate if LTCC construction meets thermal and mechanical reliability standards for the intended environment. Check if DC blocking capacitors are necessary unless a DC-pass variant is specified.

Part Context

This component belongs to the Mini-Circuits LFCN series of LTCC filters. It is part of a broader family of RF and IF components ranging from DC to 86 GHz. The LFCN series shares design principles with the LFCG series but may differ in package style or specific electrical performance metrics defined by the manufacturer.

Replacement Considerations

For DC pass functionality, consider the LFCN-2600D+ variant which provides greater than 100 MOhm isolation to ground. If DC isolation is required, coupling capacitors are recommended instead of changing the part number.
