A Pentagrid converter is a type of vacuum tube used primarily in radio frequency applications, typically in receivers and other communication devices. It is a specialized tube that integrates multiple functions into a single device, including amplification, mixing, and oscillation. The term "Pentagrid" refers to the tube's design, which incorporates five grids that work together to provide these functionalities. The Pentagrid converter is most commonly found in superheterodyne receivers, where it serves as a frequency converter.
