ALF-5000+

Overview

The ALF-5000+ is a thin film low-pass RF filter manufactured by Mini-Circuits, designed for surface-mount applications. It features a 3-SMD module package with dimensions of 8.13mm length, 5.59mm width, and 2.15mm maximum height. The component operates with a 5GHz bandwidth and a center frequency of 5.77GHz. Key electrical specifications include an insertion loss of 1.7dB and a system impedance of 50 Ohms. The device supports a power handling capacity of 39 dBm and complies with RoHS3 standards.

Feature Summary

• Thin film construction for reliable signal conditioning in RF circuits
• Surface-mount design compatible with automated assembly processes
• High power handling capability suitable for demanding transmission environments

Applications

• RF signal path filtering in communication systems
• Harmonic suppression in transmitter outputs
• Signal integrity maintenance in high-frequency test equipment

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging configuration matches your production requirements. Confirm that the 3-SMD module footprint aligns with your PCB layout constraints. Ensure compliance with RoHS3 regulations if required by your project specifications. Check manufacturer documentation for any updates regarding moisture sensitivity levels or handling instructions prior to procurement.

Selection Notes

Select this component when a low-pass filter with a 5GHz cutoff is required for 50 Ohm systems. Consider the 1.7dB insertion loss impact on overall system gain. Evaluate the physical dimensions against available board space. Verify that the 39 dBm power rating exceeds the maximum expected signal level in the application to prevent component damage.

Part Context

This part belongs to Mini-Circuits' ALF series of thin film low-pass filters. These components are engineered for consistent performance across wide frequency ranges. The series utilizes advanced thin film technology to achieve precise cutoff characteristics. This model specifically targets applications requiring robust filtering up to 5GHz with minimal signal degradation.

Replacement Considerations

The LFCW-5000+ is a documented alternative LTCC low-pass filter from Mini-Circuits offering similar DC to 5000 MHz coverage. Verify package compatibility and electrical parameter alignment before substitution. Consult official datasheets for both components to confirm mechanical and functional equivalence.
