On December 1, 2017, Broadcom announced obsolescence of over 1,000 part numbers from the former Avago brand product catalog, including the remainder of their millimeter-wave IC or MMIC devices. And this December 2018 is Broadcom's last shipment month for Avago MMICs.
Custom MMIC is aware of various and continued industry-wide obsolescence of GaAs and GaN MMIC amplifiers and other devices from large suppliers like Broadcom Avago. It’s impacting ongoing legacy production needs and even new RF and microwave hybrid assembly and system design decisions across the industry.
While we've created a cross reference to Custom MMIC alternatives (based on approximate electrical performance) to the obsolete Broadcom Avago amplifier line and other MMICs, unfortunately, none of Custom MMIC’s standardized MMIC devices are direct, drop-in replacements. Many are functional alternatives for you to consider, however, and we also offer customized MMIC engineering, fabrication, and packaging services.
We remain focused on the needs of your military, aerospace, space and instrumentation applications for MMICs. We have introduced dozens of high performance GaAs and GaN MMICs over the last few years, and offer quick turn-around on evaluation boards and samples. As you’ll find, our website has full MMIC product data sheets and downloadable s-parameter data to help you evaluate your various MMIC amplifier, control device, and mixer options.
To request immediate price and delivery of any of our MMICs, visit our RFQ page.
To learn more about the Broadcom / Avago announcement and what to do when obsolescence happens, here's an excerpt from Pat Hindle of the Microwave Journal:
"With all of the semiconductor industry consolidation, there are many RF and microwave parts being discontinued or obsoleted after a rationalization of the merged companies is complete. As bigger companies consume smaller ones, they typically will stop supporting and investing in designs that have lower demand even though many customers need them in existing designs and programs. This trend will certainly continue...
A recent example happened in Dec, where Broadcom (Avago) released an obsolescence notice containing more than 1,000 GaAs MMICS and discrete transistors covering many different applications and functions. The last time buys for these have to be done by June 2018 with delivery by Dec 2018 (with the exception of one part). This leaves a lot of customers without a source for existing and replacement parts.
These actions do open opportunities for the smaller and medium sized MMIC manufacturers to fill the void if they are willing to focus their resources on helping the customers find replacements or substitutes. Companies like Custom MMIC, MACOM, Microsemi, IDT, Marki, Guerrilla RF, Ommic and others are filling some of these voids but it can still be difficult to find acceptable replacements for all of these parts.
We talked with Custom MMIC as they have a concentrated effort to service their military and aerospace customers and are working with many of them already to find or design similar or replacement parts.
Custom MMIC had some good advice for designers when selecting a source:
Be strategic in the selection process looking ahead for long term support and stability of the company
Keep an eye on supplier status as mergers and acquisitions change a company’s focus
Watch out for changes in strategies of key suppliers making sure they match your needs
They also noted that as a fabless company, Custom MMIC second source selected products so their customers are not left out in the cold if a fab obsoletes a process. This just shows how important sourcing issues are for designers who typically might not consider this aspect in their everyday work."
