IBM develops ultra-small millimeter wave chips that break through communication bottlenecks

Scientists at IBM announced that they have reached a new milestone in the development of millimeter-wave IC technology, which is expected to break through the data bottleneck of mobile communications and allow radar imaging devices to be reduced to the size of notebook computers; the company said that Millimeter wave bandwidth can support Gbps-level wireless communication, expand mobile backbone networks, small cellular infrastructure, and data center coverage network deployment business opportunities.

It is understood that IBM scientists have developed a phased-array transceiver (phased-array transceiver), which contains all the high-data rate communication and high-resolution radar images necessary millimeter wave components; IBM participated in the research project Researcher Alberto Valdes-Garcia said that the key development of the new chip is the high integration of all necessary components, including the integration of the transmitter, receiver and all antennas into a single package.

Our breakthrough is to increase the degree of integration of silicon-based solutions at this frequency; "Valdes-Garcia said in an interview with the American edition of EETImes that most of the existing millimeter-wave components are made of III-V semiconductor materials, not silicon materials.

The highly integrated phase array chip developed by IBM is 6.7mm X 6.7mm. It adopts the company's SiGe BiCMOS process technology, contains 32 receivers and 16 transmission elements, and supports 16 dual polarized (dual polarized) The dual output function of the antenna.

IBM said that the company's complete solution, including antenna, package and transceiver chip, can convert the signal between millimeter wave and fundamental frequency, and its overall size is smaller than a 5 cent dollar coin.

Valdes-Garcia said that the frequency range of the new chip is very suitable for high-resolution radar imaging applications because of its short wavelength, relatively low atmospheric attenuation (atmospheric attenuaTIon), and the ability to penetrate rock layers (debris). IBM pointed out that the IC can reduce the size of radar equipment and assist pilots through clouds, dust, or other substances that impede vision; the chips are produced using the company's silicon germanium process.

IBM's packaged transceivers operate at 90 ~ 94GHz, and integrate 4 phased array ICs and 64 dual-polarized antennas into a single tile package (unit TIle); by arranging the package components one after another In the above, a scalable phase array with a large aperture can be produced, while maintaining the uniformity of the antenna unit pitch. The beamforming function brought by hundreds of antenna elements can support communication and radar imaging applications at distances of up to several kilometers.

Each brick package contains 4 phased array ICs, integrates 32 receivers and 16 transmission units, has dual output functions supporting 16 dual-polarized antennas, and has multiple operating modes, including synchronous reception level and Vertical polarization.

The appearance of the highly integrated phase array chip package developed by IBM is smaller than a 5 cent coin; the diamond-shaped object on the package element is the antenna, and the spacing between the antennas is precisely consistent, and can be combined with other chips to form a larger Array.

Rental Generators

Rental generators are portable power sources that can be hired or rented for temporary use. They are commonly used in situations where there is a temporary need for electricity, such as during construction projects, outdoor events, or power outages.

Rental generators come in various sizes and power capacities to meet different needs. They are typically fueled by diesel, natural gas, or propane, and can provide electricity to power equipment, appliances, or even entire buildings.

The rental process usually involves contacting a generator rental company and specifying your power requirements. The company will then recommend a suitable generator and provide delivery, setup, and maintenance services. Rental generators are typically rented on a short-term basis, ranging from a few hours to several weeks or months, depending on the customer's needs.

Renting a generator can be a cost-effective solution compared to purchasing one, especially for one-time or infrequent power needs. It also allows for flexibility, as the generator can be easily returned or exchanged if the power requirements change.

When renting a generator, it is important to consider factors such as power capacity, fuel efficiency, noise levels, and any additional accessories or services required. It is also crucial to follow proper safety guidelines and ensure that the generator is used and maintained correctly to prevent accidents or damage.
