Subject Company: TriQuint Semiconductor, Inc.

Commission File No.: 000-22660

Date: April 24, 2014

To:	Certain RFMD Employees
Subject:	Special Cash Retention Program

In February, we announced our agreement to merge RFMD and TriQuint, creating a new industry leader with unrivaled technology during a time of unprecedented innovation and growth in our industry.

When the merger is complete, we will be a different and better company where employees will have the opportunity for exciting careers in a stronger, faster growing company that is recognized as an industry leader.

We understand that the period of time between now and the closing of the transaction has a lot of uncertainty, as we work through the integration planning that needs to be done to launch the new company.

It is important for you to understand the steps that RFMD is taking to minimize the impact of this uncertainty for employees.

You should have already received an e mail message from me dated April 23, 2014, which describes how your unvested equity awards will be handled in the context of the merger. Please review this e mail. It is very important to you and your family, because it includes:

• An explanation of the way your unvested equity will be converted to shares of the new company

• A description of circumstances where your unvested equity may be accelerated if your employment is terminated as a result of the merger, and not for performance or cause

You may also be eligible for a severance payment if your employment is terminated as a result of the merger. This will depend on the local laws and regulations in the country where you are employed and the circumstances surrounding your termination.

In addition, RFMD has implemented a special cash retention program for a small number of people identified by senior management as key people we want to remain with the company during the post-closing transition period.

Under this program, you will be eligible to receive an additional cash severance payment equal to [    ] months of your base salary if you remain an employee in good standing during the transition period (up to [    ] months) and have your employment terminated as a result of the merger and not for performance or cause.

Your participation in this program does not affect your ability to participate in RFMD’s Employee Cash Bonus Plan or Sales Incentive Plan, if you are otherwise eligible to participate in these plans.

We trust that the potential benefits and payments described in the attached document will help reduce any uncertainty you might have and allow you to focus on your current work for RFMD and on the integration of our companies to create one of the strongest companies in our sector.

We encourage you to review your Fidelity account to understand the current value of your unvested RFMD stock awards.

If you have any questions about your unvested equity, please contact Todd Bender in RFMD’s Tax and Treasury Department.
