Kyocera AVX has released low-ESR C0G/NP0 dielectric RF MLCCs (multi-layer ceramic chip capacitors) “inspired by communications market demand for smaller RF capacitors that deliver repeatable performance”, it said. Called KGU, they come in values from 0.1 to 100pF with tolerances as low as ±0.05pF. They come in four chip sizes: 01005, 0402, 0603 or 0805 (EIA). Class I C0G, also ...

Toshiba has just released a 700MHz to 5GHz single-pole, double-throw antenna switch in a 1.9 x 1.9mm WCSP package. “TCWA1225G offers an input peak power of 46dBm – at 8dB PAR,” the company said. “This has been achieved by adopting Toshiba’s original CMOS process and optimising the internal switching circuitry.” The process also reduces insertion loss, typically to 0.6dB at ...

I came across a delightful design by the un-named person behind 101 Things, a blog and a YouTube channel. It is an up-to-30MHz software defined radio using a Raspberry Pi Pico for the local oscillator and… …. most of the rest of the radio. Very pleasantly, this design introduced me to a ‘Tayloe’ down-converter (after Dan Tayloe), which uses a ...

Component distributor Richardson RFPD is stocking a 5 to 8GHz GaAs pHEMT low noise linear amplifier from Guerrilla RF, and has added it to its design support service. Measuring 1.5 x 1.5mm (DFN-6), GRF2110 is aimed at WiFi 6/6E, small cell and wireless infrastructure. It operates from 2.7 to 6V, drawing 70mA at 5V. Power is applied to the output ...

Honeywell is buying CAES Systems Holdings from private equity firm Advent International for approximately $1.9 billion in an all-cash transaction. The acquisition is intended to “enhance Honeywell’s defense technology solutions across land, sea, air and space”, said the company. Specifically, for Honeywell’s Aerospace Technologies business, it will include new electromagnetic defence systems for end-to-end radio RF signal management, and introduce ...

Taoglas has inset one antenna inside another to cover GNSS L1 and L5 with a 35 x 35 x 4mm surface-mount device – which is optimised for use on a 70 x 70mm ground plane. Designed using a custom electro-ceramics formula, HP5354.A offers “stacked patch L1-L5 performance” within a single patch-in-a-patch solution, according to the company. It “has a passive ...

We're talking AI chips, a 300GHz radio receiver front-end, and space terminals in a mesh network to communicate from LEO to GEO...

A mixer-first sliding-IF architecture has been chosen by a PhD student to create a 300GHz radio receiver front-end using 300GHz Ft (450GHz Fmax) transistors from a 130nm SiGe BiCMOS process. According to the thesis of Sumit Singh, studying at University of Oulu in Finland, down-conversion of the 300GHz carrier is initially by a local oscillator at two-thirds of the carrier, ...

Teledatics is planning a 1W (30dBm) Wi-Fi HaLow wireless interface module, according to fabless chip company Newracom, which is supplying the key IC, an NRC7394. The module, to be called TD-Halom, will measure 18 x 13.5mm and 2.4mm high, and operate over 902 – 928MHz, which is only applicable to the Americas (ITU region 2). 30dB is the maximum power ...

NI has set out its stall for AI in the test industry. Following the announcement of LabView AI assistant at the end of last year (currently in beta testing), CTO of technology and innovation, Kevin Shultz spoke to Electronics Weekly about what will be the role of AI in test. He explained that the increasing complexity of products being tested ...
