• Cellular radio antenna switches

RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package style and quantity options. The base part number indicates an axial leaded HIPAX package. Confirm RoHS compliance status and any available military screening requirements such as MIL-STD-750 testing if required for the intended deployment environment.

RF Diode Selection Notes

Select this component for designs requiring robust power handling in HF through UHF frequency ranges. The 100 V reverse voltage rating and 0.5 Ω series resistance make it suitable for moderate power switching tasks. Ensure the application operates within the specified junction temperature range of -55°C to +175°C and respects the absolute maximum ratings to prevent permanent damage.

RF Diode Part Context

This device belongs to the MACOM MA4P MELF & HIPAX series of high-power PIN diodes. The series utilizes silicon technology with a thick intrinsic region and long carrier lifetime to maintain low series resistance and capacitance. The HIPAX variant specifically refers to the rugged ceramic axial leaded packaging designed for high reliability in demanding environments.

RF Diode Replacement Considerations

Consult the manufacturer's datasheet for direct cross-references within the MA4P family. Alternative packages such as MELF (e.g., MA4P4001F-1091T) offer surface mount options with similar electrical characteristics but different thermal and mechanical properties.
