HFCW-8400+

Overview

The HFCW-8400+ is a high-pass filter manufactured by Mini-Circuits, utilizing LTCC technology for signal conditioning. It operates within a frequency range of 9200 to 18000 MHz and features a cutoff frequency of 8.4 GHz. The component maintains a standard impedance of 50 Ohms and is housed in a JC0603C surface-mount package. Designed for robust performance, it supports an operating temperature range starting from -55°C.

Feature Summary

• High-pass filtering capability with specified cutoff characteristics
• LTCC construction for reliable signal conditioning
• Surface-mount design compatible with automated assembly

Applications

• RF signal conditioning
• Microwave circuit integration
• S-band upconverter assemblies

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm technical specifications before procurement. Ensure compatibility with system impedance requirements and operating temperature ranges. Cross-reference part numbers to avoid confusion with similar low-pass variants or different series components from the same manufacturer.

Selection Notes

Select this component when a high-pass response is required above 8.4 GHz. Consider the LTCC construction for stability and the 0603 footprint for space-constrained designs. Verify that the 50-ohm impedance matches the surrounding circuitry. Evaluate thermal performance against the minimum operating temperature specification.

Part Context

This component belongs to Mini-Circuits' family of RF and microwave filters, which span DC to 86 GHz. The HFCW series specifically addresses high-pass applications using LTCC technology. These components are designed for general-purpose signal conditioning in communication systems requiring precise frequency rejection below the passband.

Replacement Considerations
