‘Short’ bodied USB A connector saves PCB space

GCT has launched a short body style USB 2.0 type-A connector to cut PCB footprint to 131mm2. Called USB1125, shell depth has been cut to 10mm, although predicted rated life has been kept high – 5,000 mating cycles – through work on the six sprung retention tabs. 5,000 cycles gets the connector a ‘high-durability’ rating ...

Software defined radio offers 16x 1GHz bandwidth up to 18GHz

Per Vices has introduced a wide-band software defined radio (SDR) offering up to sixteen independent Rx and Tx chains, with 1GHz rf bandwidth on each chain, up to 18GHz. Called Cyan, it is a direct conversion quadrature transceiver built around an Altera Stratix 10 FPGA with an on-chip quad-core Arm Cortex-A53 MPCore processor, “providing the highest ...

Hanover installs more collaborative robots in Sussex

Sussex-based Hanover Displays has installed a second lot of collaborative robots – ‘cobots’. Cobots are designed to work alongside and interact with humans in shared space. They differ from traditional robots in that they are safe around people, rather than having to be caged or in other ways separated. Electronics Weekly covered these safety aspects in an ...

1.2kW fan-free low profile ac-dc PSU for industrial and medical works at 100°C

Cosel has added a 1.2kW conduction-cooled ac-dc power supply to its TUNS series. For medical and industrial use, TUNS1200 is only 12.7mm high (117 x 87mm footprint) and weighs <280g. “TUNS1200 is suitable for applications requiring a silent power solution such as in a surgery room,” according to the company. “Equally, it is suitable for industrial applications ...

Nanoparticle layer makes brighter LEDs

Researcher at Indian Institute of Technology (IIT) Guwahati have found a way to get more light out of LED die using nano-scale metal particles. This has nothing to do with making the particles into phosphors. Instead, is is a way of preventing light bouncing back into into a conventional LED die from the die-encapsulant boundary ...

Monolithic laser on silicon is electrically-pumped

The University of Arkansas is claiming a first – an electrically-pumped germanium-tin laser grown monolithically on silicon. Electrical pumping is a big deal – many proof-of-concept semiconductor lasers, including an earlier version of this device, have to have their operating energy delivered optically through other lasers. However, the laser still requires cryogenic cooling to function. ...

1W 0603 SMD 50Ω terminators work from DC to 67GHz

Smiths Interconnect has released a series of high frequency surface mount chip PCB line terminations. Called CTX SMT, and based on thin-film construction, the devices work across dc-67GHz and handle up to 1W of power. VSWR is typically 1.25:1, and 1.50:1 max in a 50Ω system, and 10x pulses can be handled (1µs at 1% ...
