ZFHP-0R055-S+

Overview

The Mini-Circuits ZFHP-0R055-S+ is a coaxial lumped LC high-pass filter designed for RF applications. It operates within a frequency range of 0.07 MHz to 1000 MHz with a cutoff frequency of 55 kHz. The component features a 3 dB passband characteristic and maintains a standard 50 Ω impedance. It supports an input power rating of 1 W and utilizes SMA connectors for interface connectivity.

Feature Summary

• Lumped LC construction for compact form factor
• Coaxial housing design for signal integrity
• SMA connectorized interface

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter chains
• Interference filtering in test and measurement equipment

Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to ensure correct connector type and tolerance specifications. Confirm that the operating environment remains within the specified 1 W power limit and temperature range. Cross-reference the part number with authorized distributors to avoid counterfeit components, as passive RF filters are sensitive to handling and storage conditions.

Selection Notes

Select this component when a sharp cutoff near DC is required alongside broadband performance up to 1 GHz. The lumped LC topology offers size advantages over distributed line filters at lower frequencies. Ensure system impedance matches the 50 Ω specification to minimize reflection losses. Evaluate insertion loss and return loss parameters from the datasheet graphs for precise link budget calculations.

Part Context

This model belongs to the ZFHP series of high-pass filters manufactured by Mini-Circuits. The series provides various cutoff frequencies while maintaining consistent electrical characteristics and mechanical dimensions. It is engineered for general-purpose RF applications requiring reliable attenuation of low-frequency signals above the cutoff point.

Replacement Considerations

Consult Mini-Circuits documentation for direct substitutes within the ZFHP series with different cutoff frequencies. Verify mechanical compatibility if space constraints are critical. No alternative manufacturers are officially confirmed for this specific part number.
