MEMS electrostatic relay switches 25W across dc to 18GHz

  Menlo Micro has released another MEMS electro-mechanical relay, this time a single-pole four-throw (SP4T) dc-18GHz switch. MM5120 will handle 25W (150W pulsed), according to the company, though its 5.2 x 4.2mm LGA package. Insertion loss is typically <0.6dB at 12GHz. IP3 linearity is said to be >95dBm. Contact movement is though electrostatic attraction, with the necessary ...

Large sky blue perovskite LED, perhaps for lighting

Large-area sky-blue perovskite LEDs have been created at the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences. The precursor, a CsPb(Br0.84Cl0.16)3 solution using a custom solvent blend, was blade-coating onto a substrate where the substance crystallised into grains – halide amine additives controlled he growth of perovskite grains and passivate ...

Government looking to facilitate digital identities

Following a public consultation, the government has announced it will introduce legislation to make digital identities as trusted and secure as official documents such as passports and driving licences. Digital identities, which are a virtual form of ID, reduce the time, effort and expense that sharing physical documents can take when people need to provide ...
