This letter introduces a W-Band sequential power amplifier (PA) (Lehmann and Knoechel, 2008) with a novel output network designed to minimize passive and combiner losses, while reducing the overall ...

The Dynaco ST-70 is one of the most popular tube amplifiers ever. First released in 1959, it's still sought after by hi-fi enthusiasts today.

However, in MHz WPT systems this assumption is not accurate anymore due to the nonneglectable rectifier input reactance. This paper discusses the impedance characteristics of the full-bridge rectifier ...
