The growing worldwide demand for mobile wireless communications and mobile multimedia applications is driving the proliferation of mobile devices. The evolution of mobile wireless networks from predominantly voice-centric networks to advanced high-speed networks that deliver voice, video and data is enabling consumers to access bandwidth-intensive, rich media content on mobile devices through applications such as videoconferencing, streaming media and interactive gaming.
With over 40 different frequency bands being used across the globe to support LTE, the number of bands a mobile device needs to support is quickly growing. This is even true for a regional-specific handset due to the band fragmentation that LTE has created. As a result, mobile devices have evolved from supporting only a single cellular standard, operating on two or three frequencies and utilizing a single antenna to supporting multiple wireless protocols, supporting many frequency bands and integrating multiple antennas. This complexity is driving the need for improved RF performance—specifically linearity, isolation and bandwidth. The increased complexity in mobile wireless devices means RF filter and RF switch content must grow exponentially compared to other components in the RF front-end (RFFE).
The growing combinations of mode and band are exponentially increasing the complexity of mobile devices. These combinations drive the need for a reconfigurable RFFE. The ability to quickly and simply optimize reference platforms and mobile devices for global or regional SKUs has significant savings in terms of time to market, the reduction in the level of required RF expertise and improved multimode, multiband performance.
Peregrine’s expertise in RF design delivers high-performance RF switch and tuning components to handset manufacturers around the world. Peregrine is building on this strong base with the Global 1 integrated RFFE products—the first reconfigurable RFFE solution.
