PLANO, Texas--(BUSINESS WIRE)--June 21, 2005--

New MT2262 Tuner is Industry`s First Single-Chip Tuner for TV-on-Handheld Devices That is Optimized for the Single-Band U.S. DVB-H Network

Microtune(R), Inc. (Nasdaq:TUNE), inventor of and a market leader in single-chip TV tuner technology, today added the industry`s first dedicated L-Band tuner to its new family of mobile TV tuners. Complying with the digital video broadcast-handheld (DVB-H) industry standard, the new Mobile MicroTuner(TM) MT2262 is a specialized, ultra low-power silicon TV tuner that supports the L-band frequency range (1670-1675 MHz) licensed for mobile broadcast TV services in the U.S. It enables manufacturers to target the U.S. market in bringing high-quality broadcast TV and digital entertainment services to cell phones, laptops, PDAs and mobile handheld devices with a cost-optimized solution.

Built with Microtune`s patent-pending Mobile MicroTuner technology, the MT2262 is a sister device to Microtune`s MT2260 multi-band DVB-H TV tuner, the first member of the product line which the company unveiled two weeks ago.

``Consistent with our pioneering silicon tuner product strategy, our Mobile MicroTuner portfolio will offer customers choice,`` said James A. Fontaine, President and CEO of Microtune. ``Our multi-band DVB-H tuners provide a flexible, common platform for manufacturers to develop handsets for worldwide markets without re-engineering hardware or software. Now, our single-band MT2262 tuner permits manufacturers to target the U.S. with a cost-optimized solution for Crown Castle`s planned DVB-H network. It also offers all the differentiating advantages of our Mobile MicroTuner technology -- high functional integration, very low power and design flexibility.``

Fabricated in silicon germanium, the MT2262 is a single-chip tuner, engineered to deliver a low noise figure for outstanding sensitivity, high linearity for reduced interference and excellent phase noise for maximum video fidelity.

Unlike competitive products, the MT2262 L-band tuner includes all active circuitry required to implement the complete radio frequency (RF)-to-baseband tuner function. A single-ended architecture eliminates the need for a transformer balun, while the L-band low noise amplifier (LNA) has also been fully integrated. These design approaches reduce components, cost and power -- key considerations for manufacturers in driving mobile TV capability into high-volume handsets.

The MT2262 operates from a 2.7V power supply and consumes 20-40 milliWatts in `viewing` mode, depending on the severity of the reception environment. It features 9-milliWatt power-down and 250-microWatt sleep modes to further conserve battery power. As with the multi-band MT2260 tuner, this low-power consumption enables mobile phone manufacturers to give viewers up to 10 hours of TV viewing time on 2-inch or 4-inch displays using 800mAh or 1300mAh batteries, respectively, for their DVB-H handsets.

The MT2262 measures only 6 x 6-square millimeters and is offered in a 40-pin QFN package. Its miniature size is ideally suited to the significantly reduced footprint designs of leading mobile phone and handheld device manufacturers for their DVB-H handsets. Additionally, the MT2262 is designed to interface directly with leading DVB-H demodulators, providing handset manufacturers the design flexibility to choose the optimum tuner-demodulator combination for their needs.

As a member of the Mobile MicroTuner family, the MT2262 L-Band tuner is pin-compatible with the multi-band MT2260, enabling manufactures to use the same designs and software for greater efficiencies and accelerated time-to-market in developing a family of DVB-H devices.

Price and Availability

The MT2262 tuner is sampling starting in July and will be priced at $4.00/unit in quantities of 10,000.
