Requirements for reconfigurable 4G front-ends

This talk will present the stringent requirements of 4G systems, and the goals that reconfigurable circuits must achieve for a successful insertion in multi-band 4G front-ends. Despite of ever increasing number of bands, modes and radios, mobile phones need to be kept at reasonable form factor, cost, performance and power consumption. The RF front-end develops more and more to a bottleneck limiting cost, size and performance of future radios. This introduces challenging, but also very attractive insertion opportunities for tunable and reconfigurable devices based on GaAs/SOI/SOS/BST or MEMS technologies.
