Smiths Interconnect has released a series of high frequency surface mount chip equalisers for controlling gain variation up to 40GHz with a maximum slope of 4dB. Called the CEX series, the parts combine thin-film and thick-film processing, offer multiple slope (1-4 dB) and band options. They come in standard and high-frequency versions. In the high-frequency types ...

Power transistor maker GaN Systems has teamed up with Renesas to produce evaluation kits that demonstrate appropriate drive techniques for GaN power transistors – which have desirable switching characteristics, but tricky gate drive requirements. They are based around Renesas’ RAA226110 low-side GaN FET driver. “These cards are the industry’s first to provide programmable over-current protection with ...

Researchers at Nagoya Institute of Technology have found a way to create a 3D map of carriers inside silicon carbide power transistors without sawing them up, proposing the system as a way of improving SiC bipolar devices. The technique, which works down to 250μm and has ~10μm resolution, is ‘time-resolved free carrier absorption with inter-sectional lights ...

The thermoelectric effect can be used to produce entangle photons, according to scientists from Finland, Russia, China and the USA. The proof-of-concept device is superconducting and has layered graphene (green) and metal (blue) electrodes on a silicon dioxide substrate (grey). “Superconductivity is caused by entangled pairs of electrons called Cooper pairs,” said Nikita Kirsanov of Aalto ...

German PSU maker Puls Power has announced a 40A-rated DIN-rail-mounted controller for uninterruptible power supply systems. Called UB40.241, it doubles current capacity compared with the company’s earlier top-end model. The controller mediates between an external 24Vdc power supply (±25%) and external battery pack to bridge power failures and voltage fluctuations by charging the battery when system ...
