The system-on-a-package (SOP) concept is considered as the solution of future communication modules, where more functionality, better performance, low cost, and more integrity is needed. We demonstrate how SOP technology can address the integration platform for future communication systems, especially gigabit wireless communications. After the introduction of the SOP concept, we introduce the critical design building blocks which are required in a viable SOP technology: integrated passives, embedded RF functions, including high-performance filters and baluns, and integrated antenna technologies. Second, we review how the three-dimensional deployment of core elements, such as baluns, lumped inductors, capacitors, and resistors, as well as IF or low-pass filters, enables RF-SOP module development. We demonstrate how advanced radio architectures, including direct conversion, antenna diversity, and collaborative signal processing, are enabled using the SOP technology format. Various ceramic and organic material based multilayer packaging technologies have been used for building such integrated modules as well as circuit blocks. The critical issues and challenges for developing advanced communication platforms using the SOP approach are discussed.
