The simultaneous deployment of multiple wireless connectivity imposes an unprecedented challenge in terms of interoperability, power consumption, PCB area and bill of material (BoM) for portable end user wireless devices such as PDAs, laptops and smart phones - which will drive the industry to seek innovative solutions for multi-system radio transceiver integration.

The main market requirements required for such a multi-system radio transceiver solution are:

·     Power consumption: The average efficiency of the complete transmission unit, particularly the average efficiency of the power amplifier, must increase at moderate and low power levels to increase the battery life.

·     Scalability: The future generation of wireless access networks must be re-configurable, allowing multi-system operation. The flexibility of multiple system operation must be accomplished with minimum impact on the power consumption, footprint and cost of the system.

·     PCB area: Even higher level of integration than today’s solutions, is needed to accommodate the increasing functionality. The reduction the PCB area allocated to the multi-standard radio transceiver in converged wireless device is mandatory.

·     BoM: Reduction of the chip count and BoM associated with the semiconductor IC are required.
