ZXLF-K122H+

Overview

The ZXLF-K122H+ is a coaxial reflectionless low pass filter manufactured by Mini-Circuits, designed for signal conditioning in RF systems. It operates from DC to 1200 MHz with a 50 Ohm impedance. The device utilizes a UK3042 case style and provides a cutoff frequency of 1.6 GHz. Key electrical characteristics include an insertion loss of 0.5 dB typical, a stopband suppression of 47 dB typical, and a passband return loss of 11 dB typical.

Feature Summary

• Reflectionless architecture prevents harmonic energy reflection into the source circuit
• Coaxial construction ensures stable signal integrity across the operating bandwidth
• Designed for precise signal conditioning within defined frequency ranges

Applications

• RF signal chain filtering
• Harmonic suppression in communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific suffix and package type against the official Mini-Circuits datasheet to ensure compatibility with your design requirements. Confirm that the operating frequency range aligns with your system specifications before procurement. Check for any recent updates to the component's pinout or mechanical dimensions.

Selection Notes

Select this component when reflectionless performance is critical to prevent source instability caused by reflected harmonics. Ensure the 50 Ohm impedance matches your system interface. Consider the UK3042 package size constraints during PCB layout planning. Validate thermal management needs based on expected power levels within the DC to 1200 MHz range.
