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 ...
Richardson RFPD is stocking 0402 (1005 metric) glass sandwich resistors designed to work from dc to 40GHz. Made by Kyocera AVX, and called the UBR series, they measure 1 x 0.5 x 0.5mm and have a flexible termination. “‘Flexiterm’ is a surface-mountable, automotive-qualified termination that adds an extra margin of protection against damage due to flexure during installation,” according to ...
TDK has introduced a radio wave absorber material with more than 25% or biomass by weight. Called the IS-BP series, the foams are intended to line the ceiling, walls and floor of microwave anechoic chambers used to evaluate antennas and wireless communication equipment, as well as millimeter-wave radar for automated driving. They consist of polyethylene loaded with carbon, and there are ...
A University of Pennsylvania team has turned to yttrium iron garnet to build a non-volatile microwave filter than can be tuned across 3.4 to 11.1GHz. “What’s special about YIG is that it propagates a magnetic spin wave,” said research engineer Troy Olsson. The team is researching filters for 6G communication in ‘frequency range 3’ – FR3, 7 to 24GHz. “At these ...
East Coast Microwave is stocking cryogenic isolators from DiTom Microwave, designed to operate “at or below 77K”, according to East Coast. Taking D3I4080Y as an example, it operates from 4 to 8GHz and can handle average forward inputs up to 30W, peaking at 50W. Maximum reverse input power is 2W. “The component provides more than 16dB of isolation and has ...
If countries A and B sign a treaty agreeing to put certain nuclear warheads into storage, how do they know the other is not cheating? German and US scientists think they might have the answer, using a technique much like the PUFs – physically uncloneable functions – used in add unpredictable unique identity numbers to ICs. “The technology combines cyber-physical ...
Beams of electromagnetic radiation can be used to detect the rotation of distant objects if they have orbital angular momentum – known as ‘vortex waves’. It involves exploiting a rotational form of the Doppler effect, and researchers from University of Shanghai for Science and Technology (USST) have managed to get the technique working at terahertz (THz) frequencies. “To the best ...
Researchers at the University of Otago in New Zealand can’t quite point to a patch of free space and measure any microwave field that exists there, but they almost can. In a proof of concept, they positioned a passive glass sensing capsule up to 30m away from novel type of reader, and then interrogated the cell with lasers. “Importantly, compared ...
Würth Elektronik introduced N type 50Ω cable and PCB connectors to MIL-STD-348. PCB jacks are available in straight and angled through-hole versions, or as four-hole flanged panel connectors with round post or solder cup. Cable-end versions (pictured right) are available loose for field assembly, or pre-assembled onto cables (including N-type to SMA adaptors, picture below), and there are coax bulkhead ...
Pickering Interfaces has announced a range of PXI and PXIe microwave relay modules capable of switching signals up to 110GHz in 50Ω. They will be reveals for the first time at IMS in San Diego next week. 40-781A-92x (PXI) and 42-781A-92x (PXIe) consist of either a single or dual microwave changeover switch. Connections are via front panel SMA 1.0 connectors, ...
