Energy storage by the Farad, Part 3: Hybrid supercapacitors
For operating and backup power and energy storage, engineers can choose among batteries, supercapacitors, or “best of both” hybrid supercapacitors. Just as with rechargeable batteries, supercapacitors need proper management to optimize their performance and avoid mishaps. In many ways, the supervisory requirements for both are similar but there are some differences. Vendors of power-management ICs […]

Energy storage by the Farad, Part 2: Supercapacitors & batteries
For operating and backup power and energy storage, engineers can choose among batteries, supercapacitors, or “best of both” hybrid supercapacitors. The previous part of this article established the context for supercapacitors and explained their structure in simplistic terms; obviously, this is a component with deep physics, chemistry, materials-science considerations, and manufacturing issues. The first widely […]
Energy storage by the Farad, Part 1: Supercapacitor basics
Engineers can choose between batteries, supercapacitors, or “best of both” hybrid supercapacitors for operating and backup power and energy storage. Many systems operate from an available line-operated supply or replaceable batteries for power. However, in others, there is a need in many systems to continually capture, store, and then deliver energy to power the system. […]
GaN power amplifiers deliver high RF output, ensure signals retain characteristics
Satellite communication systems use complex modulation schemes to achieve the blazingly fast data rates required to deliver video and broadband data. To attain this, they must deliver high RF output power while simultaneously ensuring the signals retain their desired characteristics. The new GMICP2731-10 GaN MMIC power amplifier announced by Microchip Technology Inc. helps meet both of these requirements. […]
