END OF PRODUCT LIFE ANNOUNCEMENT
Marki Microwave is announcing the end of product life for numerous Microlithic Mixer and Doubler
products. Despite our multi-year attempts to maintain a viable diode supply, we have recently been
informed by our sole supplier that they will no longer support us with these diodes. Secondary
sources for these diodes have been pursued but none are suitable for full rate production.
Please see the affected part numbers and the recommended MMIC replacements on the attached
Appendix A.
Effective immediately Marki will no longer accept requests for quotes or purchase orders for
Microlithic products beyond current stock availability. We have a limited supply of diodes on hand
to fill to fulfill existing/new orders; regretfully we cannot guarantee a last time buy to all customers.
Requests will be evaluated on a case by case basis.
For any questions regarding the above information, or how to acquire samples of recommended
product replacements please contact Dragana Rajkovic at Dragana@markimicrowave.com.
The following part numbers are NOT affected by the above diode
disruption and will continue to be available for purchase.
