VHF-8400+

Overview

The VHF-8400+ is a 50Ω coaxial high pass filter manufactured by Mini-Circuits. It features a cutoff frequency of 8.4 GHz and operates within a passband of 9000 to 13000 MHz. The device utilizes LTCC technology and is housed in a rugged unibody construction with SMA connectors. It provides good impedance matching within the specified frequency range.

Feature Summary

• Constructed using rugged unibody design for durability
• Utilizes LTCC technology for stable performance
• Provides effective signal filtering above the 8.4 GHz cutoff

Applications

• RF signal processing systems requiring high-frequency filtering
• Communication equipment operating in the 9-13 GHz range
• Test and measurement instrumentation

Procurement Notes

Verify the specific connector type and pinout configuration against the official Mini-Circuits datasheet before integration. Confirm that the SMA interface matches your system requirements. Ensure the 50Ω impedance specification aligns with your circuit design to maintain signal integrity and proper matching within the 9000 to 13000 MHz passband.

Selection Notes

Select this component when a fixed high-pass characteristic is required starting at 8.4 GHz. It is suitable for applications needing reliable attenuation below the cutoff frequency while maintaining low insertion loss in the 9000 to 13000 MHz band. Consider the SMA interface compatibility and unibody form factor for space-constrained RF modules.

Part Context

This part belongs to the Mini-Circuits VHF series of high-pass filters. These components are designed for radio frequency applications where precise frequency discrimination is necessary. The VHF-8400+ specifically targets higher microwave frequencies, offering a specialized solution for filtering out lower frequency noise or interference from desired signals.

Replacement Considerations

Check for direct substitutes such as the VHF-8400 if the plus suffix denotes a specific revision or compliance update. Verify that any alternative maintains the identical 8.4 GHz cutoff and 9000-13000 MHz passband specifications to ensure functional equivalence in existing designs.
