Amplifier achieves 235GHz bandwidth, paves way for ultra fast broadband
1 min read
A collaboration between UCL and Sweden's Chalmers University of Technology has resulted in the widest band amplifier yet reported.
The device has been shown to exceed frequencies of 235GHz and achieve a gain of 15dB, translating to a gain bandwidth product of approximately 1.5THz.
The design team claims the amplifier is at least twice as fast as the nearest competitor and believes it could pave the way for ultra fast broadband.
"This technology will help make ultra fast broadband possible for widespread use, not only for communication systems but also for different scientific and test and measurement instrumentation," said Professor Izzat Darwazeh, head of UCL's Communications and Information Systems group.
The work was led by Prof Darwazeh and Professor Herbert Zirath, head of the Microwave Electronics Laboratory at Chalmers. It builds on earlier research carried out by the pair in 2012 to design circuits at frequencies approaching the THz region.
Prof Zirath commented: "This result is of considerable interest for the development of new products within the area of communication and instrumentation such as fast oscilloscopes, pulse amplifiers and fast fiber optic receivers."
