Certain medical and scientific instrumentation applications require amplification and measurement of microvolt-level signals. For example, accurately measuring the output of a thermopile-based ...

Scientists at the University of Cambridge in the UK have built a high-gain terahertz amplifier by adapting a 2.9 THz quantum cascade laser (QCL). An antireflective coating was deposited on the QCL's ...

RF power amplifiers are going wide and high to meet wider frequency ranges and the need for more bandwidth. Many wireless electronic systems operate over wide frequency ranges and the need for more ...
