HFCU-1882+

Overview

The HFCU-1882+ is a miniature low temperature co-fired ceramic (LTCC) high pass filter manufactured by Mini-Circuits. It operates within a frequency range of 19.5 to 35 GHz, providing a bandwidth of 15.5 GHz. The component features an insertion loss between 2.1 and 3 dB and supports a power handling capacity of 7 W. Designed for surface-mount technology, it utilizes an 1812 (4532 Metric) footprint and maintains a 50 Ohm impedance system.

Feature Summary

• Constructed using low temperature co-fired ceramic (LTCC) technology for compact integration
• Provides high-pass signal conditioning with specified attenuation characteristics above the cutoff frequency
• Engineered for surface-mount assembly in standard RF circuit layouts

Applications

• Wireless communication systems requiring high-frequency signal filtering
• RF front-end modules in microwave equipment
• Test and measurement instrumentation operating in the Ka-band range

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update specifications over time. Confirm that the 1812 package dimensions align with your PCB design constraints. Ensure that the 7 W power rating is sufficient for your application's peak power levels to prevent component degradation. Check for any required termination resistors or matching networks if not included in the reference design.

Selection Notes

Select this component when a high-pass response starting at 19.5 GHz is required in a space-constrained environment. The LTCC construction offers reliability suitable for automated assembly processes. Consider the 2.1 to 3 dB insertion loss when calculating total link budget losses. The 7 W power handling capability makes it suitable for moderate-power applications compared to smaller passive filters.

Part Context

The HFCU series from Mini-Circuits includes multiple high-pass filter variants designed for wideband microwave applications. These components utilize LTCC technology to achieve small form factors while maintaining performance in high-frequency ranges. The series typically covers passbands from approximately 15.3 GHz to 33 GHz, serving various wireless infrastructure needs.
