New applications for mmWave technology often begin when fundamental design concepts are applied to solve real-world problems in novel ways. Examples include passive imaging systems to detect hidden materials, using their radiation signatures, or high bandwidth communication links difficult to detect or jam. To create a working prototype, the design process typically involves sketching a block diagram including the mmWave components, performing a system analysis to determine system and component performance, then selecting components that can be easily integrated to create the subsystem.

Eravant helps this development process with a wide range of commercial off-the-shelf (COTS) components, supported by block diagrams on the company’s website. The block diagrams reference the product families of the various components used in mmWave systems, and many suggest part numbers from Eravant’s COTS catalog. Design examples are provided, with technical notes that describe a subsystem’s operating principles. The block diagrams offer designers a starting point to conceptualize the form and function of a prototype system, and the design examples provide references for exploring options with Eravant’s technical staff.

In most cases, Eravant has components immediately available for prototyping, and the company can construct and test integrated subassemblies to shorten the time between concept and a working prototype. Eravant can also provide ancillary components such as power supplies, voltage regulators and control devices. One example is an eight-channel FMCW radar transceiver with antennas, which can be used for scanning objects. Eravant offers a fully assembled subsystem operating from 70 to 75 GHz (model SSC-7337331202-1212-B1). Documents describing this and other subsystems are available on Eravant’s website.
