The terahertz part of the electromagnetic spectrum between millimeter waves and optical range remains a largely untapped, difficult-to-use resource; researchers are investigating different techniques for efficiently generating terahertz waves to promote the use of this part of the spectrum. Electromagnetic energy in the terahertz (THz) region of the spectrum, nominally 300 GHz/0.3 THz to 10 […]

The microstrip antenna, Part 2: Implementation
The microstrip antenna is a convenient, planar, easy-to-fabricate antenna with some attractive attributes and features, as well as some distinct limitations. Part 1 of this FAQ was a brief review of antennas and introduced to microstrip antenna design. This part continues that exploration along with related issues. Q: What’s the difference, if any, between a […]

RF downconverter platform extends the life of existing RF test equipment to meet 5G requirements
ThinkRF Corp. announced the new ThinkRF D4000 RF Downconverter. The platform is the industry’s first 40 GHz downconverter, allowing engineers to quickly and reliably analyze the new 5G wireless standard by extending the range of their existing RF test equipment. To leverage the performance, latency, and capacity that 5G promises, you need equipment which can […]
What are the functions and principles of S-parameters? Part 1
As design frequencies now routinely go into the hundreds of MHz and tens of GHz range, conventional voltage and current measurements are not useful. However, scattering (s) parameters can fully characterize the RF component or path performance. For engineers with experience focused from DC to several hundred megahertz, it is usually sufficient to characterize components […]
