XLF-252+

Overview

The XLF-252+ is a reflectionless low-pass filter manufactured by Mini-Circuits, designed for signal conditioning applications. It operates with a cutoff frequency of 3.22 GHz and supports a passband from DC to 2500 MHz. The component features a 50 Ohm impedance and exhibits an insertion loss of 1.6 dB. It is housed in a compact 12-VQFN exposed pad surface-mount package. This device ensures minimal signal reflection within its operational bandwidth.

Feature Summary

• Reflectionless design minimizes signal reflections across the operating band
• Low-pass filtering capability up to 2500 MHz passband
• Surface-mount construction in a 12-VQFN exposed pad package

Applications

• RF signal conditioning circuits
• S-band upconverter assemblies
• General RF and microwave system integration

Procurement Notes

Verify the specific suffix designation when ordering. The '+' suffix indicates RoHS compliance. Confirm the exact part number variant, such as XLF-252-DG+, if dice form or specific environmental ratings are required. Ensure the procurement documentation matches the intended package type and regulatory standards for your manufacturing process.

Selection Notes

Select this component when a reflectionless low-pass response is critical for system stability. The 3.22 GHz cutoff provides a distinct transition between the 2500 MHz passband and stopband. Consider the 12-VQFN package dimensions for PCB layout constraints. Verify that the 1.6 dB insertion loss meets the link budget requirements for the specific application frequency range.

Part Context

This component belongs to the XLF series of reflectionless filters from Mini-Circuits. These devices integrate absorptive termination to prevent signal reflections that can destabilize active components. The XLF-252+ specifically targets frequencies up to 2.5 GHz, offering a solution for systems requiring clean spectral shaping without the need for external terminations.

Replacement Considerations

Public confirmed substitute part numbers include XLF-252-DG+. Verify compatibility regarding package type and electrical specifications before substitution.
