Higher RF Performance and Power Densities



The broadcast industry is rapidly moving to digital modulation from the analog modulation schemes it has employed for more than 70 years. After February 2009, digital broadcasting in the United States will replace all analog modulation schemes, and nearly all broadcasters throughout the world will soon be "fully digital". This conversion places significant demands on the transmitter's power amplifier as well as the RF power transistors because the signals have very high peak-to-average ratios. As a result, RF power transistors designed for this application must exhibit extremely high linearity under a wide range of operating conditions, as well as high efficiency and ruggedness to ensure long operating life.

Freescale has a comprehensive portfolio of broadcast devices to support the needs of FM, VHF and UHF transmitter equipment. Freescale's technical expertise delivers RF high power transistors for broadcast communication systems that combine performance, linearity, efficiency and ruggedness to meet your needs.
