The airwaves above your house are packed with signals that usually live side-by-side with no problems, but sometimes interference can occur. When it comes to digital TV reception, cellular signals on ...
When it comes to actual antennas in the real world, much of our knowledge is empirical. We know very broadly theories that explain how a point charge radiates (Maxwell’s equations), the need for ...
Non-Foster circuit design offers a transformative approach to overcoming the intrinsic limitations of traditional passive matching networks. By utilising active elements to generate negative impedance ...
STMicroelectronics has released nine chip-scale passive RF balun ICs that include antenna impedance-matching and harmonic filtering for its STM32WL sub0GHz wireless microcontrollers. Intended to sit ...
To use a smaller antenna, we need a higher signal frequency, and that’s what we do when we apply modulation to the signal. Modulation is simply encoding the low frequency signal in the information of ...
