SUBJECT: Initial organizational design for our combined company

I am pleased to announce the top level organizational structure and senior leadership team for the combined company we are building through the merger of TriQuint and RFMD. Establishing the top level structure of our new company is an important milestone in our integration planning. These executives have proven track records at their respective companies and will help lead the organization in achieving our goals once the merger closes. Effective Day One, which is the day the merger closes, the following executives will report directly to me and begin operating under the new structure.

Roles with leaders already selected (no changes to prior announcement):

n Steve Buhaly as Chief Financial Officer – responsible for finance, investor relations and regulatory reporting

n Dean Priddy as Executive Vice President of Administration - responsible for HR, IT, integration and synergy value creation

n James Klein as President of Infrastructure and Defense Products – responsible for product marketing, R&D, design centers, pricing, sales and specialized sales support

n Eric Creviston as President of Mobile Products – responsible for product marketing, R&D, design centers, pricing, sales and specialized sales support

n Steve Grant as Corporate Vice President for Fab Technology & Manufacturing – responsible for production, fab technology, and process engineering

n Jim Stilson as Corporate Vice President for Assembly/Test Technology & Manufacturing - responsible for assembly, testing and technology, process engineering, prototyping, and supply chain

Roles decided with leader not yet selected - we will interview a qualified set of candidates before selecting the best leader for each of the following roles:

n Chief Marketing Officer – responsible for our brand, website, marketing communications, public relations, and internal communications

n Corporate Vice President of Quality – responsible for all corporate quality functions including customer quality, supplier quality, and Failure Analysis/ Reliability labs

n Corporate Vice President of Business Development and Strategy– responsible for supporting company level strategy development and mergers and acquisitions (M&A)

n General Counsel – serves as Secretary to the Board of Directors with responsibility for all corporate legal matters, including legal filings, intellectual property (IP) and technology licensing, contracts, and litigation activities

Our goal is to complete the selection process for CEO direct reports before the close of the merger. We remain committed to a fair and transparent process for decisions about our combined organization and sharing what we know as early as feasible.

The leaders named in the first section of this integration update are defining the structure and determining leadership for their groups, and will announce their respective management teams once final decisions have been made. We appreciate your patience during this phase of the planning process, and ask that you continue to stay focused on your current business priorities.

Remember to visit the Integration MattersSharePoint site if you have questions about the integration. As a reminder, you can submit your own questions one of three ways:

1. Post anonymously via the Integration Matters web form

2. Email us at IntegrationMatters@RFMD.com

3. Ask your manager or local HR representative

We may not be able to answer all of your questions due to legal requirements, but we will answer as many as possible and continue to add to the FAQ listing. We will continue to share what we know when we know it.

Thank you for your continued hard work to ensure the success of our combined company and this integration. I look forward to sharing additional updates and milestones along our exciting journey together.

Sincerely,

Bob Bruggeworth
