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 ...
Dr. Ali Sadri considers how some of the limitations for 5G performance can be overcome, for example via RIS and in-building wireless coverage. With the rollout of 5G continuing to cause issues around the globe, some people would argue that it’s not yet living up to the hype. So what’s needed to unlock its potential? Dr. Ali Sadri, CTO of ...
Nanusens has demonstrated a mems digitally-tuneable capacitor for 5G and 6G RF front-ends, that is compatible with CMOS IC processing and can be integrated with circuitry. The Q-factor is above 100 at 1GHz, and the four-bit capacitor has a minimum capacitance of 450fF (30fF/capacitor) with them all off and tunes up to ~1pF – a capacitance ratio of 2.2 which ...
The Mobile Core Network (MCN) is expected to decline 10% between 2024 and 2028 due to economic headwinds – primarily the high inflation rates – and the slow adoption of 5G Standalone (5G SA) networks by Mobile Network Operators (MNOs), says Dell’Oro. “This is the fifth consecutive time we have reduced the growth rate of the MCN market as the ...
At the IEEE VLSI Symposium this week, Imec revealed two ADCs for 5GHz ‘beyond 5G’ communication, one for base stations and one for phones. The base station ADC operates over bands up to 5GHz. It is a 10Gsample/s cmos hierarchical time-interleaved ADC that delivers 9 ENOB (effective number of bits) at low frequencies and 8.2 ENOB at Nyquist. SFDR (spurious-free ...
Telecom operators are scaling back their investments in 5G, reports Dell’Oro. Worldwide telecom capex, the sum of wireless and wireline/other telecom carrier investments, declined for the full year 2023 in nominal USD terms, recording the first contraction since 2017. This deceleration in the broader capex spend isconsistent with the aggregate telco equipment slump previously communicated for the six Dell’Oro telecom ...
NEC has developed a RAN autonomous optimisation technology that dynamically controls 5G Radio Access Networks (RAN) according to the status of each user terminal, thereby improving the productivity of applications such as the remote control of robots and vehicles. NEC will incorporate the technology into RAN Intelligent Controllers (RIC) and conduct demonstration tests using this technology by March 2025. There ...
What are the topics covered this week? There's Nvidia revenues rising, Russia accessing advance ICs, space-based 5G connectivity, SIA forecasting 13% growth this year, and Weller soldering kits...
AST SpaceMobile, which aims to build a space-based cellular broadband network accessible by everyday smartphones, has announced strategic investment from AT&T, Google and Vodafone. The goal is for its in-orbit technology to eliminate cellular connectivity gaps around the world. In addition to the $155 million invested by the companies, AST SpaceMobile plans to draw up to $51.5 million from the ...
The RAN market is headed down, says Dell’Oro. Following the >40% rise between 2017 and 2021, RAN revenues stabilised in 2022, and are on target to decline sharply in 2023. Market conditions are expected to remain challenging in 2024 as the Indian RAN market pulls back, though the pace of the global decline this year and for the remainder of ...
