Pasternack has announced the launch of a new series of high performance waveguide fixed attenuators designed specifically for mmWave applications.
mmTron announced it has secured a design win and accompanying production order for mmWave power amplifier MMICs, to be used for mmWave 5G fixed wireless access.
Young EMC engineers often wonder where some of the rules of EMC originated. The answer is frequently found in the history of the EMC Society and the early work of a cadre of intelligent and active engineers who spearheaded the formation of the Society. This article highlights the story of some of these engineering professionals and their contributions to the engineering solutions practiced by today’s EMC engineers.
