On-chip RF transformers could shrink thanks to rolled-up membrane design
Researchers at the University of Illinois say they have devised more efficient RF transformers by depositing conductors on a membrane that, once complete, rolls up to create a high-turns-ratio transformer. The transformers consist of two sets of rolled-up coils deposited on some kind of SiNx material. Researchers say they’ve used the technique to realize up […]
Bulk acoustic wave filters make life easier for Wi-Fi front-end designers
BAW filters help overcome the biggest challenges facing Wi-Fi front-end designs, including thermal management, interference, and RF linearity. Cees Links |Qorvo Wireless Connectivity Smart homes are getting smarter. So they increasingly make heavy demands on their internet routers, so much so that traffic demands are exceeding the capacity of the single-router model. Retailers and businesses […]
