Role of filters in Wi-Fi 6E
The proliferation of 4G LTE networks, deployment of new 5G networks, and ubiquity of Wi-Fi is driving a dramatic increase in the number of radio frequency (RF) bands that wireless devices must support. Each band requires filters for isolation to keep signals contained in the proper “lane”. As tr...Read more -
Butler Matrix
A Butler matrix is a type of beamforming network used in antenna arrays and phased array systems. Its main functions are: ● Beam steering – It can steer the antenna beam to different angles by switching the input port. This allows the antenna system to electronically scan its beam without ...Read more -
