GaN-on-Si power transistors suit use in macro wireless basestations
MACOM has announced the latest entries in its MAGb series of GaN on Silicon power transistors for use in macro wireless basestations. Based on MACOM’s Gen4 GaN technology, the MAGb-101822-240B0P and MAGb-101822-120B0P power transistors harness the clear performance benefits of GaN in rugged, low-cost plastic packaging, enabling improved cost efficiencies that further distinguish MACOM’s GaN power transistors as the natural s...
Origami ninja star inspires super efficient battery
A disposable battery that folds like an origami ninja star could power biosensors and other small devices for use in challenging field conditions, says an engineer at Binghamton University, State University of New York. Seokheun "Sean" Choi, assistant professor of computer and electrical engineering at Binghamton University, along with two of his students, developed the device, a microbial fuel cell that runs on the bacteria available in a few dr...
Fuel gauges monitor battery life in mobile devices
The MAX1720x and MAX1721x ModelGauge m5 battery fuel gauges from Maxim Integrated are now in stock at Mouser Electronics. These ultra-low power, stand-alone fuel gauge ICs feature low quiescent currents and programmable alert functions for voltage, temperature, current, and state of charge (SOC).
Next-gen batteries use a pigment electrode
Calcium ion batteries (CIBs) have attracted much attention as next-generation batteries to replace lithium ion batteries (LIBs) because the theoretical capacity of CIBs is twice that of LIBs. This doubled capacity can be explained by the difference between monovalent and divalent ions. In addition, CIBs possess advantages such as a lower cost and higher safety because calcium is more abundant than lithium and because CIBs have a higher melting po...
