In-line strain gauge analogue amplifier to streamline calibration
A new in-line strain gauge amplifier from Mantracourt Electronics is set to streamline the calibration of a sensor thanks to its digital potentiometers and extremely simple and intuitive toolkit. Designed to convert strain gauge or load cell inputs into a 4-20 mA output, it provides more filtering than the existing embedded strain gauge amplifier range (ICA), and due to its small design, it can be easily integrated into compact installations.
So, what are S-parameters anyway?
Modern high-speed analogue-to-digital converters (ADCs) have enabled the direct sampling of radio frequency (RF) signals, which in many cases eliminates the need for mixing stages while increasing system flexibility and capability. Traditionally, ADC signal and clock inputs have been represented by lumped element models.
Precise atomic clock receives a performance upgrade
Microchip has announced, via its Microsemi subsidiary, the MHM-2020 hydrogen maser atomic clock that improves typical long term stability performance by nearly ten times over the previous generation MHM-2010. Building on the MHM-2010’s long service life and cost of ownership legacy, the MHM-2020 offers an upgraded user experience with a colour touch panel display and secure network management port.
Highly sensitive SPAD devices based on modular process technology
X-FAB Silicon Foundries continues to develop semiconductor solutions to address the most difficult of design challenges. It has now announced the availability of Avalanche Photodiode (APD) and Single-Photon Avalanche Diode (SPAD) products for implementation in scenarios where there are extremely low light conditions to contend with and augmented sensitivity is required, as well as tight timing resolutions involved.
USB Type-C port switch to support audio signals and legacy data
Diodes Incorporated has announced the PI3A6386 USB Type-C multimedia port switch, designed to enable manufacturers to continue supporting legacy data and analogue peripherals through USB Type-C ports. As a result of the adoption of USB Type-C ports in mobile phones and tablets, manufacturers are removing other ports such as USB 2.0 and 3.5mm audio sockets. The PI3A6386 port switch enables legacy data and audio signals to be passed throu...
RF converter expands call capacity for wireless carriers
Analog Devices has introduced a mixed-signal front-end (MxFE) RF data converter platform that combines high-performance analog and digital signal processing for a range of wireless equipment such as 4G LTE and 5G millimetre-wave (mmWave) radios. ADI’s new AD9081/2 MxFE platform allows manufacturers to install multiband radios in the same footprint as single-band radios, which as much as triples call capacity available in today’s 4G LT...
