Microtune Announces Second Quarter 2007 Financial Results

Company Achieves Record Quarterly Revenue with 29% Year-over-Year and 25% Sequential Revenue Growth

PLANO, Texas — Microtune®, Inc. (NASDAQ:TUNE) today announced its unaudited financial results for the second quarter and six months ended June 30, 2007.

BUSINESS HIGHLIGHTS:

Microtune’s second quarter was characterized by technology announcements and customer design-in activity that helped to solidify the Company’s position as a radio frequency (RF) leader in the digital cable market, while building momentum across applications in the digital TV markets.

CONTINUED RF MARKET LEADERSHIP IN CABLE MARKET

Microtune announced that its MicroTuner™ technology was deployed in a new DOCSIS® 3.0-based ultra-fast cable modem of ARRIS. The cable modem, which enables data download speeds of 150 megabits per second, will allow cable operators to deliver future, converged cable services (ultra-fast Internet access, fast high-definition video downloads, video file exchanges and interactive on-line gaming), while optimizing their existing networks for higher bandwidth, greater flexibility and capital efficiency. In May 2007, executives from Comcast and ARRIS featured the MicroTuner-based cable modem in a widely publicized demonstration of the capabilities of DOCSIS 3.0 at the Cable Show in Las Vegas, NV.

Adding to its portfolio of expanded bandwidth 1-GigaHertz tuners, Microtune announced during the quarter a new high-performance cable modem tuner (MicroTuner™ MT2064) designed to expand network capacity and reduce power consumption for battery-backed voice over Internet Protocol (VoIP) cable modems. When integrated into consumer cable equipment, the new MicroTuner chip enables VoIP digital phone service to meet primary-line levels of quality and functionality with increased reliability.

BUILDING MOMENTUM ACROSS MULTIPLE DIGITAL TV APPLICATIONS

During the quarter, Microtune shipped its 3-in-1 tuner (MicroTuner MT2131) to consumer electronics customers targeting U.S. digital TV applications. These customers deployed the Company’s flagship analog/digital/cable tuner in varied platforms, designed to enable superb high-definition (HD) and/or off-air digital TV broadcasts.

Microtune shipped its MT2131 tuner to a leading set-top box manufacturer to deliver HD local broadcasts in a digital video recording (DVR) satellite set-top box. Additionally, Microtune began production shipments of its 3-in-1 tuner to a contract manufacturer of a DVR brand leader to enable a dual-tuner HD set-top box for TV entertainment, multimedia and interactive services capabilities. The Company also shipped its MT2131 tuner to suppliers of HD PC-TV cards, which are currently being deployed into the desktops of two leading PC brands.
