HFCW-422+

Overview

The HFCW-422+ is an LTCC high-pass filter manufactured by Mini-Circuits. It operates within a passband of 4200 to 9000 MHz. The component provides 1.2 dB insertion loss and features a JC0603C-7 case style, corresponding to the 0603 (1608 Metric) package with a 4-pad configuration.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for compact integration
• Provides high-pass signal filtering characteristics
• Designed for S-band frequency applications

Applications

• S-band upconverter assemblies
• RF signal conditioning circuits
• Microwave communication systems

Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may update specifications over time. Confirm that the part number includes the '+' suffix, which indicates compliance with current RoHS standards. Ensure the supplier provides official documentation matching the JC0603C-7 package dimensions to avoid counterfeit or obsolete inventory issues.

Selection Notes

Select this component when a high-pass response is required between 4.2 GHz and 9.0 GHz. The 1.2 dB insertion loss makes it suitable for low-loss signal paths. Consider the 0603 footprint for space-constrained PCB designs. Verify impedance matching requirements against the system's 50-ohm standard before finalizing the design.

Part Context

Mini-Circuits specializes in RF, IF, and microwave components ranging from DC to 86 GHz. The HFCW series represents their line of LTCC high-pass filters, designed for robust performance in demanding environments. This model fits into their broader portfolio of passive components used in wireless infrastructure and test equipment.

Replacement Considerations

Consult Mini-Circuits official substitution guides for direct equivalents. Cross-reference with other LTCC high-pass filters in the same frequency range if form-factor constraints change. Ensure any substitute maintains the 0603 package and similar insertion loss characteristics.
