• Electrically tuned digital filters and AGC attenuators

RF Diode Procurement Notes

Verify component authenticity by checking MACOM branding and datasheet alignment. Confirm RoHS compliance status via official documentation. Ensure MIL-STD-19500 screening requirements are explicitly stated if military-grade reliability is needed. Validate package style matches ODS-54 specifications before procurement.

RF Diode Selection Notes

Select this part for low capacitance requirements in high isolation series switches at VHF frequencies. Compare against other ODS-54 variants like MA47600-54 for higher power handling or MA4P404-54 for lower series resistance. Consider thermal derating curves when operating near the upper temperature limit.

RF Diode Part Context

Part of MACOM's multi-purpose axial leaded glass PIN diode series. Designed specifically for commercial and military applications requiring inherent ruggedness. Available in various glass package styles including ODS 4, 139, and 146 for different power and inductance needs.

RF Diode Replacement Considerations

MA47600-54 offers similar packaging but higher power handling. MA4P404-54 provides lower series resistance in the same package. Verify electrical parameters match application requirements before substitution.

RF Diode FAQ
