Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may update internal specifications without changing the part number suffix. Confirm that the received components match the SMD package type and are free from physical damage. Ensure compatibility with your PCB footprint and reflow soldering profile prior to integration into the final assembly.

Selection Notes

Select this component when a fixed five-times frequency multiplication ratio is required within the VHF band. It is suitable for designs prioritizing low cost and small form factor over tunable frequency ranges. Engineers should verify that the input drive levels align with the multiplier's operational requirements to maintain optimal performance and spectral purity.

Part Context

This device belongs to the Mini-Circuits RMK series of surface-mount frequency multipliers. These components are engineered for high reliability in commercial and industrial RF environments. The series offers various multiplication factors and frequency ranges, providing designers with standardized building blocks for complex signal processing architectures.

Replacement Considerations

Direct substitutes include other Mini-Circuits X5 multipliers such as the RMK-5-472+ if different frequency coverage is acceptable. Cross-brand replacements require careful evaluation of harmonic content, insertion loss, and impedance matching characteristics to ensure system integrity.
