The impedance of that middle section can actually look very reactive as the length of the spacing between the grounding vias exceeds 1/8th of a wavelength. On our example FR-4 PCB operating at 6 GHz, ...

Quantum-well photodetectors fabricated from photonic metamaterials show enhanced room-temperature sensitivity to long-wavelength infrared radiation and produce gigahertz-frequency heterodyne ...

Wavelength is measured to an accuracy as high as ± 0.0001 nm. And, with a spectral resolution as high as 2 GHz and an optical rejection ratio of > 40 dB, the 771 system provides the most detailed ...

It provides ±2.5-GHz wavelength setting accuracy to minimize crosstalk on 50-GHz spaced DWDM systems. The TXN13600 also features a very low power dissipation of 8 W typical, 11 W maximum.

The research team used a technique called very long baseline interferometry at a frequency of 345 GHz (wavelength of 870 micrometers). This involved coordinating observations across multiple high ...

Peleton has released a 96-channel laser source that generates light at 96 discrete wavelengths with channel spacing of 50 GHz. Wavelength range is 1527.60 nm to 1565.50 nm. Typical output power is 3.5 ...

In addition to the more general antenna bands, the patent also specifically cites transmitting power through the 60 GHz wavelength used by the WiGig 802.11ad standard, which makes sense as a high ...

NeoPhotonics Has shipped its first 400G capable ClearLight CFP2-DCO transceivers for end customer trials. The deliver 32Tbits per fibre – significantly higher than today’s 200G CFP2-DCO capacity or ...
