Reduces Size, Offers Performance and Flexibility Meeting expectations for compact, cost-effective, reliable end products that have lower power consumption is hard to achieve if one only has low integration, building block components. Designed to reduce development time, risk and solution size of RF front end circuits in modern radios, the RF205x family of products from RFMD® provides engineers with a highly integrated, yet flexible solution. These RF205x devices use a unique system partitioning, a vertical slice through an RF section, that combine a high-performance frac-N PLL, low phase noise VCOs, LO buffers and high-linearity RF mixers. The RF205x family of products has been designed to generate a low noise LO signal of between 300MHz to 2400MHz. The built-in wideband RF mixers operate from 50MHz up to 2500MHz. The integration and optimization of key RF interfaces such as the LO-mixer interface into RF205x devices significantly reduces development time and risk while guaranteeing performance and yields.
