Highly Linear High-Power 802.11ac/ax WLAN SiGe HBT

2020-5-20 · This article presents the design of a highly linear high-power silicon-germanium (SiGe) heterojunction bipolar transistor (HBT) 802.11ac/aχ wireless local area network (WLAN) power amplifiers (PAs). The challenges associated with electrothermal effects on the dynamic operation of WLAN PAs are first discussed. We then propose the design methods that take into account the electrothermal ...

Brief review of the new Benson Germanium Boost |

2021-10-28 · The Benson Germanium Boost isn’t exactly the greatest boost pedal. While other brands, such as TC Electronic, MXR and Keeley, offer boosts of upwards to 30 db, the Benson boasts a modest eight db. What it is is a phenomenal always-on pedal to add some vintage germanium warmth to your tone without the downsides of past germanium pedals.
