In 1999, a group of innovators launched Microtune with a goal to develop the world's first single-chip RF silicon tuner. To date, Microtune has shipped more than 150 million silicon tuners. Microtune's talented engineering and product development teams did not stop there. Our company continues to advance the leading edge in RF silicon technology and product developments. In addition to our original customer base in cable TV, Microtune now also serves the automotive entertainment and digital TV markets with devices, design centers, industry-leading engineering, and applications support around the world driven by its RF Centers for Excellence.

Microtune technology is instrumental in bringing RF signals (video, voice or data) to cable subscriber equipment, automobiles, airplanes, TVs and TV peripherals, and mobile consumer electronics devices. Cable set top boxes that use Microtune tuners can incorporate multiple tuners for DVR, Tru2Way and embedded cable modem functions without being bulky and expensive. And the world's first DOCSIS 3.0 ultra high-speed cable modems, including those for 8 downstream/4 upstream channels, were deployed using Microtune's specialized wideband tuners.

Microtune is now leading the drive for high-performance tuner chips required for the worldwide transition to very thin and multi-tuner digital TV devices and is pioneering state-of-the-art silicon advances in automotive TV and radio. Around the world, brand-leading customers recognize Microtune for its superior core technology, engineering excellence, and tradition of first-to-market products.

Technology Milestones: RF-IC Performance Leader

Microtune is the world's leading silicon TV tuner supplier, with products engineered to consistently deliver the highest level of performance in the industry. Early on, Scientific-Atlanta (now part of Cisco), ARRIS, and other industry leaders recognized the value of our technology and helped us refine our products. The result is market-proven and customer-hardened integrated circuitry which continues to lead the market.

Backed by specialized teams of RF engineers on several continents, who in turn, are supported by advanced design and process capabilities, Microtune has achieved an impressive number of technology firsts:

• Introduced world's first silicon tuner
• Introduced first-of-their-kind broadband amplifier products optimized for cable and automotive electronics applications
• Introduced industry's first cable upconverter based on highly integrated custom silicon
• Introduced industry's lowest-power, highest-performance silicon tuner
• Introduced industry's first 1-GHz silicon tuner
• Introduced industry's first silicon-based architecture for multi-tuner set-top boxes
• Introduced industry's first DOCSIS 3.0 wideband cable modem tuner
• Introduced first of its kind analog/digital TV tuner chip for high-speed car TV
• The first to ship 100 million single-chip silicon tuners in the industry
• Introduced the first RF-to-digital converter for software defined radio

Testifying to its technical accomplishments, Microtune has been granted more than 80 U.S. patents that protect its technology inventions.
