VHF-1080+

Overview

The VHF-1080+ is an LTCC high-pass filter manufactured by Mini-Circuits, designed for RF applications within the 1.15 GHz to 5 GHz frequency range. It provides a bandwidth of 3850 MHz with a standard impedance of 50 Ohms. The component utilizes internal LTCC structure technology to ensure repeatable performance and features SMA termination style connectors. Built using unibody construction, it offers good rejection characteristics and low insertion loss across its specified operating band.

Feature Summary

• Utilizes internal LTCC High Pass Filter structure for consistent performance
• Constructed using proven unibody design for mechanical stability
• Provides wide bandwidth coverage from 1.15 GHz to 5 GHz

Applications

• RF signal filtering in communication systems
• Microwave circuit integration requiring high-pass characteristics
• Test and measurement equipment signal conditioning

Procurement Notes

Verify the specific datasheet version for precise electrical parameters such as insertion loss and return loss values before integration. Confirm that the SMA connector orientation matches your PCB layout requirements. Ensure environmental conditions align with the manufacturer's operational specifications for long-term reliability.

Selection Notes

Select this component when a fixed cutoff frequency near 1.15 GHz is required for frequencies up to 5 GHz. The LTCC construction makes it suitable for applications demanding compact size and thermal stability. Compare insertion loss specifications against system budget constraints to ensure signal integrity is maintained.

Part Context

This part belongs to the VHF series of high-pass filters from Mini-Circuits. The series includes variants like VHF-145 and MINI-VHF-1080+, offering different cutoff frequencies while maintaining similar LTCC construction methods. These components are part of Mini-Circuits' broader portfolio of RF and microwave passive components.

Replacement Considerations

Check for direct substitutes within the VHF series or other Mini-Circuits high-pass filters with compatible cutoff frequencies. Verify pinout compatibility if replacing in existing designs. Consider the MINI-VHF-1080+ variant if smaller footprint is needed, though electrical performance may differ slightly.
