There are design challenges for antennas, PCB connectors and components, advise Ifan Yousaf and David Currie, of TE. The environment of smart devices presents design challenges. Electronic devices are increasingly being connected to the world through one or more wireless technologies and are commonly referred to as smart devices. By 2025, it is estimated that more than 75 billion devices ...

Digital Enhanced Cordless Telecommunications New Radio plus is a new wireless communication protocol that promises to address many limitations of existing methods, filling the gap for reliable, low latency, long range communication, writes Mark Patrick of Mouser Electronics. The advent of the IoT and IIoT (industrial IoT) has brought technology into homes, cars and factories. Most of it depends heavily ...

Linx Technologies is aiming at sub-6GHz 5G New Radio, LTE, LTE-M and NB-IoT with a range of flexible stick-on antennas. Measuring 120 x 20mm, “ANT-5GW-FPC antennas provide a ground plane-independent dipole,” according to the company, which is now part of TE Connectivity. “The flexibility and adhesive backing make the series easier to mount in RF-transparent – for example plastic – ...

Infineon is aiming at wireless charging at up to 50W with a wireless power transmitter development kit. Called REF_WLC_TX50W_N1, it consists of the reference board, firmware and software utility called the ‘wireless charging configuration utility’. The design is a Qi-compatible transmitter, with an MP-A2 type transmitter coil, that delivers 50W to Infineon’s own receiver (REF_WLC_RX50W_N1) and a proprietary protocol, taking ...

Mouser Electronics has been announced as a sponsor for Nordic Semiconductor‘s Connect for Good: Low Power Wireless Sustainability Challenge, in association with Wevolver. The challenge is open to all engineers and students, ages 18 and up, with sufficient engineering capability to develop a working prototype that uses low power wireless technology to tackle one (or more) of the UN’s sustainable ...

Nordic Semiconductor has announced an SoCs for Bluetooth Low Energy, LE Audio, Bluetooth mesh, Thread and Matter with “multiple Arm Cortex-M33 processors, clocked up to 320MHz” and “multiple RISC-V coprocessors”, it said. Part of a forthcoming nRF54 series, the new IC, nRF54H20, will be fabricated on GlobalFoundries’ 22FDX process and “capable of supporting Bluetooth 5.4 and future Bluetooth specifications, plus ...

Aimed at X-band radar, 1222 is a 200W 9 to 10GHz pulse amplifier from Empower RF Systems of California. Measuring ~178 x 102 x 25mm, it can deliver pulses up to 500μs long and duty cycles up to 20%. The devices can typically hit 250W with -6dBm at the input (200W is the minimum all can achieve) when supplied with ...

The Bluetooth Special Interest Group (SIG) has released its 2023 Bluetooth Market Update, covering latest market forecasts for the short-range wireless comms technology. The report includes the SIG’s first forecast for LE Audio, Auracast deployments, and the transition from Bluetooth Classic Audio to LE Audio. It also covers new markets, such as electronic shelf labels (ESL, below right) and Ambient ...

Liberating and entertaining, mobile communications have changed the way of life for the majority of the world’s population, but does faster connectivity need to be at a cost to the planet? Dib Nath, of Advanced Energy, thinks not. Mobile communications have changed the way we live. Advances in 4G LTE have brought mobile broadband and use cases such as gaming, ...

Semtech has extended its LoRa portfolio with a transceiver for use in IoT end points that provides lower power consumption, global connectivity and long range. The LoRa Connect LR1121 is pin compatible with the current LoRa Edge devices, allowing module makers such as Murata to have a single hardware design for a wide range of applications, with global connectivity. Likewise, integrated passive ...
