Save Time and Space in Design for Coexistence with Integrated RF Modules
Applications for portable wireless data communications are on the rise with the advent of initiatives such as smart power and with rapid growth in markets for portable devices such as tablet PCs. To be successful in these applications, however, designs need to have multiple high efficiency, low-noise RF channels in as small a space as possible. By adopting integrated RF modules, designers can achieve such superior coexistence faster and more effi...
