ZXLF-K982+

Overview

The ZXLF-K982+ is a coaxial low-pass filter manufactured by Mini-Circuits, designed for signal conditioning applications. It operates within a frequency range of 0 Hz to 9.8 GHz and features a nominal impedance of 50 Ohms. The component utilizes a 2.92 mm termination style for reliable RF connections. It is engineered to function reliably across a minimum operating temperature of -40°C and a maximum operating temperature of +85°C, ensuring stability in various environmental conditions.

Feature Summary

• Coaxial construction for robust RF signal integrity
• Wideband operation from DC up to 9.8 GHz
• Standard 50 Ohm impedance matching
• High-temperature tolerance for demanding environments

Applications

• RF signal filtering in communication systems
• Signal conditioning in test and measurement equipment
• Microwave circuit integration
• Broadband receiver front-end protection

Procurement Notes

Verify the specific datasheet version and mechanical drawings provided by Mini-Circuits or authorized distributors before procurement. Confirm that the 2.92 mm termination style matches your system's interconnect requirements. Ensure the operating temperature range aligns with your application's environmental specifications. Cross-reference the part number suffix to confirm it denotes the standard commercial grade variant without special modifications.

Selection Notes

Select this component when a wideband low-pass response up to 9.8 GHz is required with minimal insertion loss. The 50 Ohm impedance ensures compatibility with standard RF infrastructure. Consider the 2.92 mm connector interface for high-frequency performance and repeatability. Evaluate thermal constraints to ensure the -40°C to +85°C range suits the deployment environment. Compare against higher-order filters if sharper roll-off characteristics are necessary beyond the basic low-pass specification.

Part Context

This component belongs to Mini-Circuits' extensive portfolio of RF and microwave passive components. The ZXLF series typically offers compact form factors suitable for space-constrained designs. As a low-pass filter, it complements mixers, amplifiers, and converters in signal chains. The '+' suffix indicates compliance with RoHS standards, reflecting current manufacturing regulations for electronic components.

Replacement Considerations

Consult Mini-Circuits official documentation for direct cross-references. Verify impedance and frequency cutoff alignment with existing designs. Ensure connector type compatibility to avoid mechanical adaptation issues. Check thermal ratings to maintain operational reliability.
