VBF-1560+

Overview

The VBF-1560+ is a coaxial bandpass filter manufactured by Mini-Circuits, designed for RF applications requiring precise frequency selection. It operates within a passband of 1500 to 1620 MHz, centered at 1560 MHz, with a bandwidth of 120 MHz. The component maintains a system impedance of 50 Ohms and utilizes SMA connectors for signal interfacing. Key electrical specifications include a typical insertion loss of 2.61 dB and an excellent Voltage Standing Wave Ratio (VSWR) of 1.1:1 within the passband. This filter is compliant with RoHS and REACH standards.

Feature Summary

• Rugged unibody construction that integrates RF connectors directly with the case body for enhanced durability
• Coaxial design ensuring reliable signal transmission in demanding RF environments
• Compliance with RoHS and REACH environmental regulations

Applications

• RF signal filtering in communication systems
• Frequency selection in radio frequency circuits
• Signal conditioning in test and measurement equipment

Procurement Notes

Verify the specific datasheet version and revision history before integration to ensure compatibility with current design requirements. Confirm that the SMA connector type matches the PCB footprint or cable assembly specifications. Check for any recent updates to the RoHS/REACH compliance status. Ensure the operating temperature range aligns with the intended application environment. Validate that the 50 Ohm impedance matches the rest of the signal chain to prevent reflection issues.

Selection Notes

Select this component when a fixed center frequency of 1560 MHz is required with minimal insertion loss. The rugged unibody construction makes it suitable for applications where mechanical stability is critical. Consider the 120 MHz bandwidth to ensure it adequately covers the desired signal spectrum without excessive attenuation of adjacent channels. Verify that the SMA interface is compatible with existing system interconnects.

Part Context

The VBF series from Mini-Circuits represents a line of coaxial bandpass filters known for their robust construction and consistent performance. These filters are part of Mini-Circuits' broader portfolio of RF and microwave components, which includes amplifiers, mixers, and other passive devices. The VBF-1560+ specifically targets applications requiring high rejection and low loss in the L-band frequency range.

Replacement Considerations

Consult Mini-Circuits official documentation for direct cross-reference part numbers. Ensure any substitute component matches the 1500-1620 MHz passband, 50 Ohm impedance, and SMA connector interface. Verify that alternative filters offer comparable insertion loss and VSWR specifications to maintain system performance integrity.
