A Primer on RF Semiconductors (MMICs) Radhakrishna Setty, Technical Advisor Introduction Semiconductors are ubiquitous in modern society. In addition to microprocessors for computing technologies, they are used in practically every active wireless communications system including cell phone towers, cell phones, radars and satellites to name a few. Mini-Circuits designs and produces several semiconductor-based (MMIC) components […]
The capabilities that define the 5G wireless standard will require utilization of wider bandwidths across more regions of spectrum than any current wireless technology. 5G communications will eventually occupy multiple bands from below 6 GHz to above 60 GHz. For now, much of the development effort is divided among sub-6 GHz bands for vehicular connectivity and longer-range transmissions, and the 26, 28, 38 and 60 GHz bands for enhanced mobile broadband applications. The migration to higher frequencies and the multi-band nature of the technology pose a variety of unique challenges for designers developing 5G devices and network equipment. Significant among these is the high cost of instrumentation for test and measurement over such a wide range of frequencies.
