HFCQ-2902+

Overview

The HFCQ-2902+ is a high-pass filter manufactured by Mini-Circuits, designed for millimeter-wave applications. It operates within a frequency range of 29 GHz to 39 GHz and utilizes LTCC technology in an NL1008C-6 surface-mount package. The component handles up to 1W of RF input power and supports a wide operating temperature range. It provides attenuation for fundamental and second harmonics while delivering the fourth harmonic.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for compact integration
• Provides clean fourth harmonic output suitable for multiplier applications
• Attenuates fundamental and second harmonic frequencies effectively

Applications

• Signal conditioning for x4 multipliers
• Harmonic generation for mixer inputs
• Millimeter-wave signal filtering

Procurement Notes

Verify the specific datasheet version and mechanical drawing for the NL1008C-6 package dimensions before PCB layout. Confirm that the 29 GHz to 39 GHz operational range aligns with system requirements. Ensure thermal management strategies account for the specified 1W RF input power handling capability during operation.

Selection Notes

Select this component when a compact high-pass filter is required for millimeter-wave frequencies between 29 GHz and 39 GHz. It is appropriate for designs needing significant attenuation of lower-order harmonics while preserving higher-order signals. Consider the LTCC construction for robustness in high-frequency environments.
