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 -
Whether Cavity Duplexers and Filters will Be Completely Replaced by Chips in The Future
It is unlikely that cavity duplexers and filters will be entirely displaced by chips in the foreseeable future, mainly for the following reasons: 1. Performance limitations. Current chip technologies have difficulty achieving the high Q factor, low loss, and high power handling that cavity device...Read more -
