Rohde & Schwarz is aiming at 6G and sub-THz research with W-band front-ends for an IF vector signal generator and a D-band thermal power sensor. SFI100A wideband IF vector signal generator The SFI100A wideband IF vector signal generator has been developed for early 6G research, high capacity wireless backhaul, fixed wireless access and automotive radar. With an RF modulation bandwidth ...

As the curtain has just risen on IAA Mobility 2023 in Munich on September 5, the leading Chinese provider of CMOS mmWave radar chips, Calterah, brings a most comprehensive portfolio of automotive radar SoCs at Booth A2-F31 of Mess München to the global audience. Figure 1 Visitors Showing Great Interest in Calterah mmWave Radar SoCs (please click on images to ...

The proposed shifter uses a half-mode substrate-integrated waveguide, with phase shifted in a via-pad-slot structure where a through via is attached to a pad surrounded by an annular slot. “The phase shifter does not need clean room facilities for fabrication,” said lead researcher Dr Yi Wang, and “the liquid-metal enabled phase shifting elements have a passive nature, unlike active semiconductor-based ...

Amphenol RF has introduced fixed-length cable assemblies with a straight SMA plug one one end and a right-angle SMP plug on the other. The right-angle SMP provides low mated height with no bend radius for low-headroom applications. The cable is Tflex 405 from Amphenol Times Microwave Systems, intended to be a flexible alternative to semi-rigid coax. The SMA plug has ...

CML has announced a pair of 6 – 18GHz GaAs pHEMT gain blocks with positive gain slopes up to 16GHz. CMX90G701 and CMX90G702 have gain-slopes of +1dB and +2dB respectively, and are intended to operate C, X and Ku bands for microwave back-haul, radar, satellite communications and 5G fixed wireless access. “They can also be used to eliminate passive equalisers ...

Filtronic has opened a design centre in Manchester, focused on developing mmWave technology for satellite communications, as well as hired several engineers for its design and its process engineering teams. “Establishing the new centre for satellite communication design has enabled us to expand our physical footprint across three UK locations: Sedgefield, Leeds and now Manchester, and has assisted us in ...

At Electronica 2022 we caught up with Dr Jiashu Chen, the CEO of Calterah, as part of our promotional coverage for the event. Dr Chen shares his thoughts on the outlook of automotive and industrial mmWave radar applications. With the full range of Calterah’s products on display, the company shows its technological evolution and confidence in the future of CMOS ...

Analog Devices, has introduced millimetre wave (mmW) 5G front-end chipsets spanning 24 to 47GHz. There are two 16-channel dual-polarisation beam formers and two single channel (one Tx + one Rx) up-down converters. ADMV4828 24 – 29.5GHz 16-channel beamformer >12.5dBm output at 3% EVM with 400MHz 64QAM 5G NR waveform 310mW/channel ADMV4928 37 to 43.5GHz 16-channel beamformer >11.5dBm output at 3% EVM ...

Georgia Tech has developed a general-purpose MMIC (monolithic microwave IC) for the direct filtering and processing of microwave and millimeter-wave signals. The aim is to reduce radio power consumption by swapping some digital signal processing elements for reconfigurable analogue processing blocks. “High-speed digitisation blocks targeting microwave frequencies are expensive and consume a lot of power,” said Georgia Tech researcher Nelson ...

Metallic inks for printing flexible conductors are well know, but how about inks for printing flexible microwave dielectics? Researchers at King Abdullah University of Science and Technology (KAUST) have developed a dielectric ink from the polymer ABS and ceramic particles. By screen-printing it onto glass, and then peeling off the dried result, flexible large-area dielectics of tunable thickness and permittivity can ...
