Abstract
This application describes a dynamically tuned front end module using a modal antenna approach for improved communication system performance. The front end module consists of power amplifiers, filters, switches and antennas along with tuning circuits integrated and controlled to provide an optimized system for RF transmission. Dynamic tuning provides the ability to maintain optimized system performance for a wide variety of use cases and environments that the wireless device is operated in. Several transmission modes are accessed in an algorithm to optimize the performance of multiple wireless devices in a cellular system, to include a power conservation mode, emergency transmission mode, and cell capacity optimization mode. Dynamic adjustment of correlation and isolation between multiple antennas is a benefit provided by this front end topology.
