Researchers at University of California, Santa Barbara (UCSB), have successfully devised a way to fabricate tunable, high-frequency integrated circuits and RF devices that adapt to changing environments using a novel material called barium strontium titanate (BST).
For many years, TWTA technology has been the only option for pulsed field generation within high field-strength EMC radiated susceptibility testing. AR now offers high-power solid state pulsed amplifiers as a very attractive alternative to this technology. These SP-series amplifiers include various frequency ranges and output power levels capable of meeting several standards. This application note discusses key features and benefits of this new line of solid state pulsed amplifiers, and how they are optimized for use in applications such as EMC radiated susceptibility testing.
AT&T Laboratories has applied with the Federal Communications Commission (FCC) for an experimental license to test 5G radios with integrated adaptive, non-line-of-sight (NLOS) antennas transmitting in the 3.5 GHz range.
University of Wisconsin–Madison electrical engineers have devised a new antenna design that allows transmission of radiofrequency signals in multiple directions by a stationary antenna with no rotating parts.
Multi-tone signals are composed of multiple single sine waves or tones with unique amplitudes, phases, and frequencies. Originally, multi-tone testing was implemented to increase the speed of immunity testing, but it also improves equipment efficiency, higher flexibility, and is fully compliant to standards. Multi-tones are also used in measuring modern audio levels in consumers and professional audio devices, broadband devices, and in internet audio. This application note further discusses multi-tone testing, the theory of the science behind it, and how to put it into practice.
