vuh-RAK-ter
Definition
A type of semiconductor diode whose internal capacitance varies based on the amount of voltage applied to it.
Etymology
The word is a portmanteau derived from 'variable' and 'reactor' (or 'capacitor'), first appearing in the mid-20th century to describe this specific electronic component.
In the news
The article mentions varactor diodes as part of a new set of nonlinear models, which are critical for RF and microwave design engineers to simulate circuit performance accurately.
