A beam tetrode is a type of vacuum tube that was widely used in electronics, particularly in radio transmitters and amplifiers, during the mid-20th century. It is an evolution of the tetrode, which itself is a four-electrode vacuum tube comprising a cathode, anode (plate), and two control grids. The beam tetrode introduces a design that enhances efficiency and performance.
