ZXHF-K482M+

Overview

The ZXHF-K482M+ is a coaxial reflectionless high-pass filter manufactured by Mini-Circuits. It operates with a passband from 4800 to 19000 MHz and a stopband from DC to 3500 MHz. The component features a center frequency of 4370 MHz and supports an average input power of 1.3 W. Designed for 50-ohm systems, it utilizes the RA2937 case style with a height of 8.8 mm.

Feature Summary

• Reflectionless design ensures impedance matching to 50 ohms in the stop band
• Coaxial construction for reliable RF signal conditioning
• Compact RA2937 package suitable for space-constrained applications

Applications

• Wi-Fi systems
• WiMax infrastructure
• Microwave radio links
• Military and space electronics

Procurement Notes

Verify the specific revision code (e.g., ECO-004178) against the manufacturer's current documentation to ensure compatibility with your design requirements. Confirm that the RA2937 mechanical dimensions align with your PCB layout constraints. Ensure the 1.3 W average input power rating exceeds your system's maximum expected signal levels to prevent component damage during operation.

Selection Notes

Select this component when a high-pass response is required with minimal reflection in the stop band. The 4800 MHz lower cutoff frequency makes it suitable for filtering out lower-frequency interference while passing higher microwave signals. Consider the 1.3 W power handling capability when designing for high-power transmission lines or test environments requiring robust signal integrity.

Part Context

This part belongs to Mini-Circuits' ZXHF series of reflectionless filters, designed for RF and microwave applications up to 86 GHz. The series emphasizes stable performance across wide frequency ranges. The ZXHF-K482M+ specifically targets high-frequency filtering needs in communication and defense sectors, offering a balance of electrical performance and mechanical durability in a standardized coaxial format.

Replacement Considerations

No public confirmed substitute part numbers are available for direct replacement.
