Bismuth-doped fibre amplifiers and lasers have emerged as promising alternatives to conventional rare-earth-doped devices, providing a broader spectral coverage that is particularly beneficial for ...

Previous installments of this article series discussed the need to verify SPICE model accuracy and how to measure the output impedance, small-signal bandwidth, and input-referred errors of operational ...

Digital predistortion is an approach to amplifier linearization that permits the efficiency of the multi-carrier amplifier to be dramatically increased. The principle of predistortion is intrinsically ...
