Integrating more software control and cognitive abilities to military radios demands a more frequency- and bandwidth-flexible radio frequency (RF) design. To achieve this goal, static filters need to be removed and replaced with tunable filters. Similarly, the concept of a common platform would allow for shorter development times, reduced manufacturing costs, and provide greater interoperability between systems. The common platform demands that the RF system be capable of providing full performance for applications that traditionally have had very different architectures. Future radio platforms are pushing size and power demands to a new extreme.
