ZHFG-K3500+

Overview

The ZHFG-K3500+ is a 50Ω high pass filter manufactured by Mini-Circuits, utilizing LTCC technology within a broadband connectorized package. It operates in the 3900-16500 MHz frequency range with a cutoff frequency of 3.9 GHz. Key electrical specifications include a typical insertion loss of 1.3 dB, a typical return loss of 12 dB, and a stop band rejection of 49 dB. The component features 2.92mm connectors for reliable interconnection.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for robust signal conditioning
• Provides effective attenuation in the stop band with high rejection capabilities
• Designed for low insertion loss to maintain signal integrity in the passband

Applications

• RF signal conditioning in microwave systems
• Harmonic suppression in communication equipment
• Test and measurement instrumentation setups

Procurement Notes

Verify the specific datasheet version and mechanical drawings before integration. Confirm that the 2.92mm connector interface matches your system requirements. Ensure environmental conditions align with the component's operational limits as defined in the official documentation.

Selection Notes

Select this component when a high-pass characteristic is required between 3.9 GHz and 16.5 GHz. Consider the 50Ω impedance match and LTCC construction for stability. Evaluate the 1.3 dB insertion loss against system power budgets and verify connector compatibility with existing infrastructure.

Part Context

This part belongs to Mini-Circuits' ZHFG series of LTCC high-pass filters. These components are designed for broadband applications requiring precise frequency discrimination. The series offers various cutoff frequencies to suit different RF and microwave design needs while maintaining consistent performance characteristics.

Replacement Considerations

Consult Mini-Circuits documentation for direct substitutes. Verify that any alternative maintains the 3.9 GHz cutoff, 50Ω impedance, and 2.92mm connector type to ensure mechanical and electrical compatibility.
