VBF-1525+

Overview

The VBF-1525+ is a surface-mount bandpass filter from Mini-Circuits, designed for signal conditioning applications. It operates at a center frequency of 1.525 GHz with a bandwidth of 90 MHz. The component features a 50 Ohm impedance and utilizes an internal LTCC structure for repeatable performance. It offers low insertion loss of 3 dB and provides good rejection at the band reject edges. The device is housed in a compact SMD/SMT package suitable for board mounting.

Feature Summary

• Utilizes internal LTCC bandpass filter structure for consistent performance
• Provides low insertion loss and effective rejection at band edges
• Designed for surface mount board integration

Applications

• RF receiver systems
• Transmitter filtering
• Wireless communication infrastructure

Procurement Notes

Verify the specific package type and termination style required for your PCB layout against the manufacturer's datasheet. Confirm that the operating temperature range meets your environmental specifications. Ensure compatibility with your assembly process for surface-mount components. Cross-reference the part number suffix to confirm RoHS compliance status as documented by Mini-Circuits.

Selection Notes

Select this component when a fixed-frequency bandpass filter centered at 1.525 GHz is required. Consider the 90 MHz bandwidth and 3 dB insertion loss characteristics for system link budget calculations. Evaluate the LTCC construction benefits for stability in high-volume production environments compared to other filter technologies.

Part Context

This component belongs to the VBF series of RF filters manufactured by Mini-Circuits. These filters are engineered for general-purpose RF signal conditioning tasks. The series includes various center frequencies to support different wireless standards and frequency bands within the microwave spectrum.

Replacement Considerations

Check for direct substitutes within the Mini-Circuits VBF series that match the 1.525 GHz center frequency. Verify if alternative LTCC or ceramic filters from other manufacturers meet the same electrical specifications and physical footprint requirements.
