RF Diode Procurement Notes

Verify the specific suffix GM2 against the official datasheet to confirm pinout and packaging details. Ensure compatibility with standard reflow soldering profiles for 4-SMD packages. Confirm RoHS3 compliance status for the specific production batch prior to assembly.

RF Diode Selection Notes

Select this component when dual independent PIN diodes are required in a small form factor. The 75V reverse voltage rating suits moderate power RF applications. Compare the 1.5pF capacitance and 2.5 ohm resistance against circuit requirements for insertion loss and isolation performance.

RF Diode Part Context

This part belongs to the MML4400 series of silicon PIN diodes. It shares the series designation with variants like MML4401-GM3, which may differ in packaging or minor electrical tolerances. The series is designed for general-purpose RF switching and limiting tasks.

RF Diode Replacement Considerations

Check for direct substitutes within the MML4400 series, such as MML4401-GM3. Verify that any alternative maintains the 4-SMD no-lead footprint and similar electrical characteristics, specifically the 75V breakdown and 1.5pF capacitance.
