HFCN-740+

Overview

The HFCN-740+ is a high-pass LTCC ceramic filter manufactured by Mini-Circuits. It operates within a frequency range of 780 MHz to 2800 MHz, featuring a center frequency of 1.79 GHz and a bandwidth of 2.02 GHz. The device maintains a standard 50 Ohm impedance and utilizes a compact 4-SMD, no lead package (Case Style FV1206). Key electrical characteristics include a typical breakdown voltage of 1 kV and excellent power handling capabilities rated at 7W. Designed for temperature stability, it incorporates DC blocking at both input and output ports.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for stable performance across varying temperatures.
• Provides effective suppression of low-frequency interference while passing desired RF signals.
• Features integrated DC blocking at input and output terminals with high breakdown voltage tolerance.

Applications

• RF filtering in wireless communication systems
• Signal conditioning in broadcast RF infrastructure
• Interference suppression in industrial measurement equipment

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may reference alternate qualified ceramic substrate materials. Confirm that the required component matches the FV1206 surface-mount case style and 50 Ohm impedance specifications. Ensure compatibility with the intended operating temperature range and power handling requirements before integration into the final design.

Selection Notes

Select this component for designs requiring a compact, temperature-stable high-pass filter with significant power handling capacity. The LTCC construction offers a cost-effective solution compared to discrete alternatives. Consider the 7-section internal structure for steep roll-off characteristics. Verify that the 7W power rating aligns with the maximum signal levels present in the application circuit to ensure long-term reliability.
