In the RF component supply chain world, some particular devices develop a very broad-based customer support network and high-volume usage. They tend to remain in production for a very long time, without the need for any longevity support programs. These are typically general-purpose driver devices from well-established RF power transistor suppliers designed into a wide variety of RF applications. They do not depend on any customer or end-use application to support their volumes, and once the parts reach broad, universal acceptance across the entire RF industry, engineers tend to design these well-known drivers into even newer product designs.
With very predictable RF performance, these general-purpose driver transistors are a known entity, with a stable and reliable supply chain, with no surprises down the road. From the OEM manufacturing point of view, so long as the particular components run in reasonable volumes on existing and stable manufacturing lines, then typically they see no need to end of life these industry-wide, popular devices.
Even if there are wafer fabrication site moves or consolidations, with a stable, large customer base, the OEM will choose to move the general-purpose device to the newer processes or new Fab to keep the broad base of customers happy.
The following list shows some of these stable, tried, and true devices expected to achieve natural longevity through their extensive, multiple customer market bases.
Should the RFMW sales team be asked to give driver recommendations, they are likely to select preferred, even recommended general-purpose driver devices. If you need more information or if you want verification of your selections, please reach out to the RFMW technical support team at any time. They are here to help you with all things technical.
