  6. When Choosing Test Equipment, Don’t Forget the Interface
    9/5/2018

    When purchasing RF test equipment, it is tempting to concentrate on specifications, such as insertion loss, frequency range, or VSWR, without think ahead on the fact that a complex testing scheme usually involves integrating multiple pieces of equipment from multiple manufacturers. For multiple devices to work seamlessly together in an automated test flow, designers and engineers must also consider the interface that would be used to drive the testing equipment. This article discusses the differences in proprietary and generic interfaces, the benefits each type has to offer, and offers some solutions to potential interface barriers and how to remove them.

  10. EM Simulation Of 28 GHz Series-Fed Patch Antenna Array For 5G
    8/17/2018

    Series-fed patch elements forming an array are simulated to demonstrate antenna performance and beamforming including S-parameters, gain, and effective isotropic radiated power (EIRP) at 28 GHz. Beam steering is performed in one plane by adjusting the phasing at the input ports to each of eight elements.
