In a flurry of announcements alongside its developer converence, Silicon Labs has revealed a chip set for metropolitan Wi-Sun radio, a low-power IC for battery-powered Wi-Fi 6 links and a hardware-software development kit for Amazon Sidewalk. Wi-Sun For Wi-Sun (which is wireless smart utility network), and proprietary sub-GHz protocols, in cities and other built-up environments, it announced an RF microcontroller ...

Eindhoven-based Altum RF has created a 400W S-band power amplifier microwave IC (MMIC) with a 50-55% PAE (power added efficiency). Operating between 2.8 and 3.3GHz, it was developed with Netherlands research organisation TNO, which has been working on phased-array high power amplifier research for more that 30 years, according to Altum, and Taiwan’s Win Semiconductors, on whose NP45-11 50V 0.45μm RF ...

Johanson Technology had announced surface-mount filters to help Wi-Fi 5, Wi-Fi 6E and Wi-Fi 7 co-exist. 5500BP44A0700 (right) comes in a 4.5 x 3.2mm 1812 package and passes 5.1 to 5.8GHz while offering 50dB attenuation to the 6GHz Wi-Fi band. It can handle 3W (CW) and operates over -40 to +85°C 6100BP14A1995 is a 6.1GHz band pass filter in a ...

Pickering Electronics has announced miniature coaxial reed relays for use up to 3GHz, with the company emphasising low insertion loss (-3dB at 3.16GHz right). Called series 113RF, single-in-line through-hole relays have a 12.5 x 3.7mm footprint and are 6.6 or 8.9mm tall. Pin pitch is 2mm. The single 1 Form A (normally-open) contact can switching up to 10W and 500mA, ...

RangeAnt has created a family of 700MHz to 3GHz antennas, designed primarily for cellular, IoT and GNSS applications. “They feature free-space efficiency of between 80 and 90% and a VSWR below 2:1 across the operating bands,” according to the company. “The high efficiency delivers greater range for available transmitter power, or a lower transmitter power can be used for a ...

Apex TG.66 from Taoglas is a hinged monopole antenna designed to cover all global 5G and 4G frequencies between 600MHz and 6GHz. “Despite its miniature size, the TG.66 has omnidirectional radiation patterns and provides stable gain across the hemisphere,” according to distributor Anglia, which is stocking the part. “The antenna packs a punch for its size, with efficiencies above 45% ...

Wireless technology and machine learning combined in an artificial pancreas help type one diabetics live unimpeded, explains Thomas Søderholm. In 2003, biological physicist Philip Nelson wrote: “At the dawn of the 20th century, it was already clear that, chemically speaking, you and I are not much different from cans of soup. And yet we can do many complex and even ...

Henkel and Chip Integration Technology Center (CITC) have agreed to collaborate on the development of high-thermal die attach solutions for RF and power electronics. Under the terms of the partnership, Henkel will supply commercialised and developmental pressureless sintering die attach formulations and CITC will provide testing and analysis of the materials within next- generation package designs. CITC’s thermal high-performance packaging ...

Linx Technologies has introduced a family of 2.4 GHz adhesive flexible printed circuit antennas for ISM applications including Bluetooth and ZigBee and Wi-Fi. They provide a ground-plane-independent dipole, according to the company, and are intended to be stuck inside plastic enclosures and other structures transparent to the frequency band “enabling environmental sealing and protection from antenna damage”, it said. Connection ...

Panasonic has introduced an external antenna Bluetooth 5 Low Energy (LE) module for use in shielded housings and enclosures. Called PAN1770, it is designed around a Nordic Semi’s nRF52840 Bluetooth IC and has a lot on common with Panasonic’s earlier built-in antenna PAN1780. Antenna connection for the PAN1770 is through a uFL connector, and 8dBm is available at the output ...
