The growing demand for wireless services not only challenges our limited spectral resources, but it also challenges the radio designer to select the correct radio architecture. A proper radio architecture provides solid performance, and it simplifies the circuit around the radio to minimize cost, power, and size.

In the era of increasing radio deployments, the “right” radio is tolerant of current and future wireless neighbors that might otherwise cause interference down the road. This article will examine two common radio architectures and compare the tradeoffs on how each solves the unique problem of escalating co-location issues.
