Overview
The VLFG-1575+ is an LTCC low-pass filter manufactured by Mini-Circuits. It provides a frequency range from DC to 1575 MHz with a cutoff frequency of 1.85 GHz. The component operates at a system impedance of 50 Ohms and utilizes SMA connectors for termination. Designed for signal conditioning, it effectively filters high-frequency signals while maintaining performance within standard industrial temperature ranges.
Feature Summary
- Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for robust construction
- Provides effective attenuation of signals above the specified cutoff frequency
- Features SMA connectors for reliable RF interface connections
Applications
- Signal conditioning in RF systems
- Filtering out high-frequency interference
- Wireless communication infrastructure
Procurement Notes
Verify the specific datasheet version to confirm connector orientation and mechanical dimensions prior to integration. Ensure compatibility with existing SMA interfaces in the design. Confirm RoHS compliance status if required by regulatory standards. Cross-reference part numbers to distinguish between variants with different mounting styles or connector types.
Selection Notes
Select this component when a sharp cutoff near 1.575 GHz is required for low-pass filtering applications. The 50 Ohm impedance matches standard RF transmission lines. Consider the LTCC construction for stability in varying environmental conditions. Verify that the SMA termination suits the board layout requirements.
Part Context
Mini-Circuits specializes in RF, IF, and microwave signal processing devices. The VLFG-1575+ belongs to their line of passive components designed for signal integrity. This series supports various wireless and industrial applications requiring precise frequency control and filtering capabilities.
Replacement Considerations
Consult official Mini-Circuits documentation for direct substitutes. Verify electrical parameters such as cutoff frequency and insertion loss match the original design requirements before considering alternative models.
