ZXLF-K252H+

Overview

The ZXLF-K252H+ is a reflectionless low-pass filter from Mini-Circuits, operating from DC to 2500 MHz. It features a 50 Ohm impedance and utilizes a novel topology that absorbs stop-band signals. The device supports a passband up to 3900 MHz with 36 dB rejection in the 7000-14500 MHz range. Additional specifications include 50 dB rejection at 14500-17000 MHz and an operating temperature range of -55°C to +105°C.

Feature Summary

• Employs reflectionless topology to absorb and terminate stop-band signals
• Provides high attenuation in specified upper frequency bands
• Designed for signal conditioning in RF applications

Applications

• Telecom systems
• Aerospace & Defense
• GPS receivers
• 4G networks
• 24-25MHz ISM band operations

Procurement Notes

Verify the specific datasheet revision (e.g., ECO-005778) matches your design requirements. Confirm the 2.92mm termination style compatibility with your interconnects. Ensure the operating temperature range of -55°C to +105°C suits your environmental conditions. Cross-reference electrical specifications against current Mini-Circuits documentation to avoid discrepancies.

Selection Notes

Select this component when reflectionless performance is critical to prevent signal re-reflection in sensitive RF chains. The 2.92mm interface offers precision for high-frequency applications. Consider the thermal range if deploying in extreme environments. Verify that the stop-band absorption characteristics align with system noise floor requirements.

Part Context

This model belongs to the ZXLF series, which distinguishes itself through reflectionless technology. Unlike traditional filters that reflect out-of-band energy, this series terminates such signals internally. This characteristic improves system stability and reduces interference in complex RF architectures requiring precise signal conditioning.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Consult Mini-Circuits engineering support for direct equivalents or functional replacements within the ZXLF family.
