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 […]
RF power measurement, Part 2: What and how
Part 1 of this FAQ introduced some of the basic issues related to the measurement of RF power, which is a primary parameter in most RF designs. Part 2 continues the discussion, looking at RF waveforms and sensors. Q: The term “power” is fairly broad; what are the specifics? A: There are actually several basic […]
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 […]
RF power measurement, Part 1: Why and where
When the subject is RF design, the word “power” dominates much of the discussion. This FAQ looks at some perspectives related to the measurement of this vital RF parameter. Not only is power and measuring it among the most important RF design considerations, but it is also generally difficult to assess accurately, and it is […]
New laminates target base station antenna apps
Rogers Corporation has introduced two new products: AD300D laminates and IM Series laminates. AD300D fourth generation, commercial microwave and RF laminate material extends the capabilities of the successful AD300 product grade. This ceramic-filled, glass-reinforced, PTFE based material provides the controlled dielectric constant (2.94±0.05), low loss performance (0.0021 at 10GHz), very good passive intermodulation response (-159dBc […]
