RF SILICON AND SUBSYSTEMS SOLUTIONS FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS MT2266 SINGLE-CHIP DUAL-BAND LOW-POWER DVB-T / DVB-H TUNER PRODUCT BRIEF The MT2266 is a direct conversion lowpower single-chip broadband tuner for VHF PRELIMINARY Band III and UHF applications. MT2266 Single Chip Dual-Band Tuner The MicroTuner™ MT2266 is a direct conversion, low-power, singlechip broadband tuner optimized for UHF and VHF Band III DVB-T and DVB-H applications. It includes all active circuitry required to implement the complete RF-to-Baseband tuner function. The MT2266 has been developed to give manufacturers design flexibility and low operating power, at low cost, without compromising high performance. The MT2266 is capable of receiving UHF band and VHF Band III frequencies, enabling manufacturers to target low-power portable and low-power PCTV devices. The combination of power management, choice of architecture, and Microtune’s patents-pending ClearTune filtering technology enables the MT2266 to operate at 325 mW. High-volume consumer markets demand low-cost products. The MT2266 was designed for low cost. The single-ended direct conversion architecture eliminates the need for baluns at the RF inputs and costly IF SAW filters. To further reduce cost and power, the UHF and VHF Band III variable gain low noise amplifiers (VLNA) and the voltage controlled oscillators (VCO) are fully integrated. The transmission environment for mobile TV is extremely hostile. Microtune's unique patents-pending ClearTune filtering technology and the excellent performance of MT2266 will help to ensure that end users will have a superior mobile TV experience without picture interruption in the middle of tall buildings or hostile radio environments.
