RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm RoHS compliance status directly with the manufacturer before procurement. Ensure that the selected variant matches the required case style and electrical parameters for your specific circuit design requirements.

RF Diode Selection Notes

Select this component when designing low power multiplier circuits requiring precise harmonic generation. Consider the SOT-23 package dimensions for surface mount compatibility. Evaluate the 30 V reverse voltage rating against peak signal levels to ensure safe operation within absolute maximum ratings.

RF Diode Part Context

This part belongs to MACOM's portfolio of surface mount low power step recovery diodes. It shares functional similarities with the MAVR-044769-1279 but utilizes a different case style. These components are engineered to meet the size, power, and signal integrity demands of modern commercial wireless systems.

RF Diode Replacement Considerations

The MAVR-044769-1279 serves as a direct alternative with identical electrical characteristics but utilizes the SC-79 package instead of the SOT-23 configuration. Verify footprint compatibility before substitution.
