RF Diode Procurement Notes

Verify component authenticity by cross-referencing the datasheet document number 200725D and manufacturer details. Confirm that the specific part number matches the Ku-band ring quad configuration. Ensure handling procedures account for electrostatic discharge sensitivity, as these devices require protection from static charges during storage and installation.

RF Diode Selection Notes

Select this component when designing Ku-band microwave circuits requiring medium local oscillator drive levels. The beam-lead package facilitates impedance control through narrow capacitance spreads. Verify that the required operating frequency falls within the 12.4 to 18.0 GHz range and that the circuit topology accommodates the four-junction ring configuration.

RF Diode Part Context

This device belongs to the DME, DMF, and DMJ series of silicon beam-lead Schottky mixer diodes. The series covers S, C, X, Ku, K, and Ka bands with varying drive levels. The DME2859-000 specifically represents the medium drive variant within the Ku-band ring quad category, designed for applications demanding low parasitics and high uniformity.

RF Diode Replacement Considerations

Direct substitutes within the same series include other Ku-band ring quad configurations such as DME2857-000 or DME2858-000, depending on the required drive level. Ensure any replacement maintains the beam-lead package type and compatible electrical parameters for the target frequency band.
