LFCN-2250+

Overview

The LFCN-2250+ is a low-pass filter manufactured by Mini-Circuits, designed for RF and IF signal processing applications. It operates with a cutoff frequency of 2250 MHz and maintains a system impedance of 50Ω. The component utilizes a seven-section LTCC structure to ensure temperature stability and robust performance. It features a compact surface-mount package, specifically the FV1206 case, which contains four pins. The device is RoHS compliant and constructed from ceramic materials. Official documentation confirms its capability to handle significant power levels, supporting high-power transmission environments effectively.

Feature Summary

• High power handling capability suitable for demanding RF environments
• Temperature-stable LTCC construction for consistent performance
• Compact seven-section design minimizing board space

Applications

• Harmonic suppression in RF circuits
• VHF transmitter systems
• UHF receiver systems

Procurement Notes

Verify the specific suffix designation when ordering, as variations such as LFCN-2250D may exist within the product family. Confirm that the required package type matches the standard FV1206 surface-mount configuration. Ensure compatibility with 50Ω system impedance requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate the cutoff frequency specification against the target application's spectral requirements before procurement.

Selection Notes

Select this component when a low-pass filter with a 2250 MHz cutoff is required for VHF or UHF bands. The choice is driven by the need for high power handling and thermal stability in a small footprint. Consider the LTCC technology for superior temperature characteristics compared to other ceramic options. Ensure the application benefits from the specific attenuation profile provided by the seven-section design. Verify that the surface-mount form factor fits the available PCB real estate constraints.
