Strategy FAQs

Why did Analog Devices, Inc. acquire Hittite Microwave Corporation?

The combination of Analog Devices and Hittite Microwave is compelling for our customers and strengthens ADI's position as a leader in high performance signal processing. The combination of ADI's 10,000 device RF/IF to baseband signal chain and complementary system components and Hittite's 1,100 RF, microwave and millimeter wave signal chain components gives our customers the expertise and solutions for high performance design. We are able to serve their needs better by providing a complete portfolio capable of converting the frequency spectrum including RF, microwave and millimeter wave. We believe this will significantly benefit our customers by creating an integrated supplier for all of their RF needs. This acquisition opens expansion opportunities into microwave and millimeter wave frequencies - technologies where Hittite Microwave specializes. ADI offers Hittite Microwave customers access to our complementary portfolio of products, a far-reaching distribution network, and access to an established set of world-class supply chain systems, partners, and practices.

What are your long-term product development plans? Will your tools (FPGA rapid prototyping platforms, reference designs, simulation tools, calculators, etc.) support Hittite Microwave products?

The newly formed RF and Microwave Group, reporting up to Rick Hess, former CEO of Hittite Microwave Corporation, combines product teams from both companies. The mission of this group is to develop high performance RF, microwave, and millimeter wave solutions. Tools are an important part of the solution and we plan to have a comprehensive set of tools across the entire RF and microwave portfolio.

What are Analog Devices' plans to support aerospace and defense electronics?

The aerospace and defense market has been and will continue to be a very important part of ADI's overall strategy. This market has driven a number of product, process, packaging, and technology developments within ADI historically, with recent examples being in high speed converters, RF transceivers, IMUs (inertial measurements units) and EP packaging. The addition of the Hittite Microwave products enhances our ability to offer aerospace and defense customers complete solutions and our plan is to further expand our portfolio with additional investments.

Will the Hittite Microwave Corporation brand change?

Hittite Microwave Corporation is now Analog Devices. Hittite Microwave's portfolio is now represented as "Hittite Microwave Products from Analog Devices."

Will the current strategy of offering customized solutions of Hittite Microwave products change?

As a result of the acquisition, there is no change to Hittite Microwave's strategy of offering flexible solutions to satisfy our customers' needs.

Do you have any plans to obsolete any RF and microwave products? What is your end of life (EOL) policy?

There are no plans to obsolete any products as a result of the acquisition. When ADI makes the decision to discontinue manufacturing of a product, our policy is to issue a Product Discontinuance Notice (PDN) in compliance with JESD48A. This provides for a 12-month Last Time Buy (LTB) period when customers may place orders and ADI continues to ship the product for up to 24 months from the date of the PDN.

Will Hittite Microwave products now be manufactured in Analog Devices fabs?

There will be no changes to the wafer fabrication of Hittite Microwave products. The current product portfolio will continue to use existing wafer fab suppliers.
