Freescale Semiconductor has introduced an RF power LDMOS transistor that combines the industry’s highest output power and efficiency with the greatest ruggedness of any competitive device in its class ...

Mobile phone use is increasing but there is also concern for adverse health effects. Well-designed prospective studies to assess several health outcomes are required. In designing a study of mobile ...

With 14 envelope-tracking-enabled handsets now on the market, and more sets to follow in the coming years, envelope tracking (ET) has been firmly accepted as the industry standard for the architecture ...

Over the years, tutorials have appeared in EMC journals explaining how to estimate the power required from a power amplifier intended for use in an RF immunity test system. Little material, if any, ...

Radio frequency (RF) power amplifiers are all over the place. Some of them can deliver enough RF output power to do biological harm to somebody. Many such amplifiers are solid state, but many others ...
