HFCW-133+

Overview

The HFCW-133+ is a high-pass filter from Mini-Circuits, designed for RF and microwave applications. It features a cutoff frequency of 13.3 GHz and operates within a bandwidth of 6.3 GHz. The component utilizes Low Temperature Co-fired Ceramic (LTCC) technology and is housed in a compact 0603 surface-mount package. Key electrical specifications include a typical insertion loss of 1.9 dB and good rejection characteristics with a typical value of 38 dB. It supports a power handling capacity of 2.5 W and is intended for use in 50-ohm systems.

Feature Summary

• Utilizes LTCC multilayer construction for miniaturization
• Provides high signal rejection in the stopband
• Supports moderate power handling capabilities
• Designed for surface-mount integration

Applications

• Test and measurement equipment
• Signal conditioning circuits
• RF system filtering

Procurement Notes

Verify the specific datasheet version and parameter tolerances directly with the manufacturer or authorized distributors before finalizing design integration. Ensure that the operating environment remains within the specified thermal limits to prevent damage to the LTCC structure or associated connectors. Confirm that the 50-ohm impedance matches the system requirements to maintain optimal performance and minimize signal reflection.

Selection Notes

Select this component when a compact high-pass filter is required for frequencies above 13.3 GHz. The 0603 package size is suitable for space-constrained PCB layouts. Consider the 2.5 W power handling limit when designing for high-power transmission lines. Verify that the 1.9 dB insertion loss meets the system's noise figure and gain budget requirements.

Part Context

This part belongs to Mini-Circuits' HFCW series of LTCC high-pass filters. These components are engineered for high performance in small form factors, leveraging ceramic technology for stability and reliability. The series is commonly used in modern wireless communication infrastructure and test instruments where size and electrical precision are critical constraints.

Replacement Considerations

Consult official Mini-Circuits documentation for verified substitute part numbers. Do not assume compatibility based on similar cutoff frequencies alone; verify package dimensions, impedance, and power handling specifications against the original design requirements.
