VLF-2500+

Overview

The VLF-2500+ is a coaxial low-pass filter manufactured by Mini-Circuits, designed for signal conditioning applications. It operates from DC to 2500 MHz with a cutoff frequency of approximately 3.075 GHz. The component features a 50 Ohm impedance and utilizes an SMA connector interface. Constructed using LTCC technology in the FF704 case style, it offers rugged uni-body construction. The device supports an input power handling capacity of 10W and maintains temperature stability across its operational range.

Feature Summary

• Rugged uni-body construction ensures mechanical durability
• LTCC technology provides excellent power handling capabilities
• Temperature stable performance across operating conditions

Applications

• RF signal filtering in communication systems
• Harmonic suppression in microwave circuits
• Signal conditioning in test and measurement equipment

Procurement Notes

Verify the specific datasheet version and electrical performance curves directly from Mini-Circuits official documentation before integration. Confirm that the SMA connector type and FF704 package dimensions match your PCB layout requirements. Ensure the 10W power handling rating aligns with your system's maximum input power levels to prevent component damage during operation.

Selection Notes

Select this component when a low-pass filter with a cutoff near 3 GHz is required for 50 Ohm systems. The LTCC construction makes it suitable for environments requiring robust thermal stability. Consider the physical size constraints of the FF704 package against available board space. Verify compatibility with SMA connectors if used in modular setups or test fixtures.

Part Context

This part belongs to the VLF series of coaxial low-pass filters from Mini-Circuits. The series utilizes LTCC technology for compact, high-performance RF filtering. These components are widely used in wireless infrastructure and industrial applications where reliable signal integrity is critical. The VLF-2500+ specifically targets frequencies up to 2500 MHz with sharp roll-off characteristics.

Replacement Considerations

Consult Mini-Circuits official substitution guides for verified equivalent models. Ensure any replacement matches the DC-2500 MHz frequency range and 50 Ohm impedance. Verify that the alternative component supports similar power handling and uses compatible SMA connectors.
