New mmWave Applications Drive Demand & Generate New Challenges: Microwave and mmWave applications beyond 6 GHz have garnered extensive interest in the last few years, largely due to growth in 5G cellular, micro-satellite constellations, mmWave backhaul, radar and Internet-of-Things (IoT) applications where increased bandwidth and reduced spectrum congestion are critical. Additional technology trends that embrace increased frequencies include active electronically steered arrays (AESA) for military radar, V-band automotive radar and V-band/E-band backhaul.
5G and IoT wireless applications are moving to 20 ~ 60 GHz frequency bands to overcome atmospheric attenuation and enhance throughput in the mmWave spectrum. Advanced active antenna systems (AAS) are being developed that incorporate beamforming, multi-inputmulti-output (MIMO), and carrier aggregation (CA) technologies, requiring greatly advanced and complex antenna systems than previous cellular or wireless IoT. All of these new technologies come with new challenges for industries that are traditionally familiar with sub-6 GHz technology. There is a new realm of expertise, equipment, and range of physical considerations for development of competitive technology that meets both customer and user requirements and expectations.
Big Opportunity Means Big Stakes: Years of producing a 77GHz Frequency Converter Module, RFE’s engagement with a large OEM led to the development of new Automotive Radar Test Systems with a complete range of capabilities with > 100 fielded systems achieving 100 percent satisfaction and reliability.
V-band Downconverter Woes: A U.S. based Radiometer provider faced obsoletion of an essential V-band downconverter that was the core of their product. Unable to source any viable replacement after more than a year of research and testing, provided RFE with a physical replica. RFE rapidly delivered a fully functional unit with updated synthesizers for backward compatibility, field replaceability, and enhancements to the K-band and V-band down-converters for reduced system drift.
Delivering Much-needed Expertise & Turn-key Manufacturing For mmWave Systems: RFE, formerly Spinnaker Microwave, has been offering products for challenging applications since 1991. With a complete design, manufacturing, quality control, tuning and testing services capabilities, RFE enables companies without microwave and millimeter-wave capabilities to reach a growing market and bring high-demand products to awaiting customers.

Enabling Next-generation Millimeter-wave Device Manufacture: RFE’s expertise and familiarity with a wide range of precision mmWave systems results in end products that outperform industry competitors. RFE offers experience and expertise combined with turn-key manufacturing or A-la-carte manufacturing services to fill the gap in any millimeter-wave design or production cycle. See the examples below:
77 GHz FMCW Radar Warning Receiver: Today’s automotive and transportation systems rely on high-reliability / high-performance radar. Target tracking, collision threat prediction, configurability and cost along are critical. In conjunction with Mobile Technology Solutions (MTS), RFE developed a 77 GHz frequency-modulated continuous wave (FMCW) radar system that exceeds the standards in the marketplace. With over 150 meters of range, RFE’s automotive radar platform is unaffected by vehicle glass and a custom designed antenna/lens system eliminates the alignment issues common with strip-line configurations.
Broadband Fast Tuning Miniature Synthesizer: Microwave and mmWave radar, radios and instruments are built using frequency synthesizers.
With more high frequency applications, synthesizers are now needed that exhibit wide bandwidth in smaller form factors than previous technologies. Predicting this emerging need, RFE has developed a broadband fast tuning miniature synthesizer that operates from 0.1 ~ 20 GHz with < 50μs tuning speed in a tiny 3 x 3 x 0.7” package with spurious content down to -60 dBc, phase noise below -65 dBc/Hz at 10 kHz and rugged operating temperature range of -45 to +85 deg C.
