Modulation advances have fueled more efficient use of bandwidth, although conventional modulation formats still require allowance for upper and lower sidebands around the carrier frequency. Ultra ...

RF front ends are advancing through the integration of high-frequency passive networks with increasingly efficient active devices engineered for ultra-wide bandwidths and constrained power envelopes.

Abstract: This article presents a supply-modulated power amplifier (PA) system architecture for a high-efficiency transmitter (TX) that utilizes a symbol-power-tracking (SPT) technique to support 5G ...

Abstract: Exploration for new dimensions to convey information is a non-trivial task for resource-limited communications. Interleaved Chirp Spreading LoRa (ICS-LoRa) constitutes a new ...

Nedap AEOS Convexs readers enable smooth migration to Mifare card technology in both existing Nedap XS systems and Nedap AEOS Enterprise systems. The reader can be connected to third party controllers ...
