NFC Tags Are Ambidextrous

via Elektor.uk: News

Inside Secure has released dual-interface near field communication (NFC) tags designed to enhance interactions between NFC capable devices. In addition to a conventional NFC contactless interface, the dual-interface NFC Forum Type 4 tags provide a unique one-wire interface that allows them to act as a low-cost wireless communication bridge between two devices.   For example, a single tap of an NFC phone on a Bluetooth wireless headset containing one of these tags can initiate pairing....

Amplifier Has Noise Figure of 0.045 dB

via Elektor.uk: News

A fundamental property for the first microwave amplifier in a radio receiver is its noise figure. This is normally given in decibel (dB). A typical noise figure for low-noise amplifiers in mobile communication systems is tenths of a decibel. Last year, Chalmers reported a world record for a low-noise amplifier that exhibited a minimum noise figure of 0.018 dB across a bandwidth of 4-8 GHz. However, since the low-noise amplifier was designed in a hybrid solution, scaling up to larger...
