Communications Technology

Connectivity is a key feature of modern embedded products. There’s a wide range of communications modes that can be used, but which is the best for your design? Should you use a wireless technology such as Wi-Fi or Bluetooth and, if so, which one should that be? Or would wired communication, such as Ethernet, be the best way forward?

In this section, New Electronics reviews the latest communications technologies and brings visitors to the website information on how these technologies are being applied.

Antennas work on metal surfaces without de-tuning

A family of antennas from Antenova has been engineered to operate without de-tuning on metal surfaces or where the product housing is mainly metal. According to the company, these situations normally make it difficult for an antenna to operate.

First 2.5 and 5Gbit/s octal Ethernet transceiver

Marvell has announced the Alaska M 88E2180 Gigabit Ethernet transceiver, which it claims to be the first compatible with both the IEEE 802.3bz standard and the NBASE-T AllianceSM specification for 2.5 and 5Gbit/s operation over CAT5e cables.

Solution to maintain colour stability and lumen output

The AS7220 Smart Lighting Manager from ams uses closed-loop sensing to maintain accurate correlated colour temperature (CCT) and lumen output. The company claims the solution could enable a new generation of higher quality LED-based lamps and luminaires.

Production ready IoT module

Said to be production ready, the Samsung ARTIK 053 module provides high-performance and hardened security for next-generation edge applications such as connected home appliances, building products, health care devices and industrial automation.

SiGe based amplifier outperforms other devices

The LTC6432-15 from Linear Technology is a wideband fully differential amplifier with 15dB gain. According to the company, recently acquired by Analog Devices, it offers a linearity of up to +50.3dBm at the output third-order intercept (OPI3dB), an output 1dB compression point (OP1dB) of +22.7dBm and a 3.2dB noise figure at 150MHz.

Ethernet switch chip is ‘TSN ready’

A real-time Ethernet Multi-protocol (REM) switch chip from Analog Devices is said to form part of its high performance deterministic Ethernet connectivity portfolio for connected motion and Intelligent Factory applications.

Family of maXTouch touchscreen controllers

The new family of maXTouch automotive-qualified touchscreen controllers from Microchip is designed for large-screen automotive human machine interface (HMI) designs. The technology brings multi-touch HMI to car drivers and passengers on screen sizes from 8 to 15in.

SiP blends MCU and sub GHz radio

The SAM R30 from Microchip is a system in package (SiP) device integrating a SAM L21 microcontroller alongside an IEEE802.15.4 sub GHz. According to the supplier, the SiP delivers design flexibility and proven reliability, making it suitable for connected home, smart city and industrial applications.

Bridge links USB to I2S

A fixed-function audio bridge from Silicon Labs is said to provide a turnkey solution for transferring digital audio data between the USB and I2S interfaces.

Imec develops bifacial n-PERT solar cell

Bifacial n-PERT solar cells have been realised using an industrially-compatible process with a front-side conversion efficiency of 22.8%, according to Imec. Featuring a transparent backside and comparable front- and back contact schemes, bifacial solar cells capture light on both sides of the cell.

Linear launches dual 10GHz differential amplifier

Linear Technology has launched the LTC6419, a dual 10GHz gain bandwidth product differential amplifier that comes with a very low input voltage noise density of 1.1nV/vHz, delivering an improved SNR performance for wideband signal amplification.

Omron widens SM photo-microsensor range

Omron Electronic Components Europe has extended its surface mount photo-microsensor range with a new 5mm slot width type, increasing the range of applications in office equipment, consumer electronics, ATM, vending machines and industrial control systems in which this device can be applied.
