Streaming services, games, cloud storage, as well as web conferencing and remote desktop services cause stress on conventional wireless networks. This creates a huge demand for wireless capacity that cannot be solved with increases to the existing spectrum. “Mobile broadband data demand will grow by a thousandfold between 2010 and 2020," Upamanyu Madhow, a professor in UC … [Read more...]
UK Flights Delayed Due to Radio Interference
Recently, passengers from Edinburgh Airport in Scotland were delayed because of a technical issue with air traffic control. “It is understood the problem stemmed from ‘radio interference’ on frequencies used to speak to aircraft pilots – with the cause of the interference apparently resting on a faulty piece of equipment,” the Stornoway Gazette reported. According to a … [Read more...]

China Producing World’s Largest Radio Telescope
A large engineering and scientific project in China, led by the country’s military-led space program, is creating the world’s largest radio telescope, which will be able to detect radio signals from tens of billions of light years away. The Telescope is known as FAST, which stands for Five-hundred-meter Aperture Spherical Telescope. When the project is complete, the dish on the … [Read more...]
High School Students and UPenn Professor Build Radio Telescope in West Philadelphia
This past summer, as part of UPenn’s Summer Science Academy Program, 12 high school students along with James Aguirre, associate professor in the School of Arts & Sciences’ Department of Physics and Astronomy, turned an out-of-service TV satellite dish on the roof of the Enterprise Center in West Philadelphia into a 30-foot radio telescope. The telescope has been given the … [Read more...]
GaN Coaxial Power Amplifiers
Pasternack recently launched its increased offering of gallium nirtride (GaN) coaxial power amplifiers. “The high power density of gallium nitride semiconductor technology dissipates heat more effectively which results in amplifier designs that have significantly higher output power levels over broadband and narrowband frequencies,” according to the company. This technology … [Read more...]
High Power Coaxial Limiters Handle up to 200 Watts
Fairview Microwave Inc. announces a new family of broadband, high power coaxial limiters that protect sensitive components and RF receivers that are close to high power signals. Depending on the model, the limiters operate on frequencies ranging from 0.5 GHz to 40 GHz. The limiters also offer seven different design options, a low leakage power of 10 to 15 dBm and limited … [Read more...]
