Abstract
The behavior of planar triodes with close grid-to-cathode spacings is investigated theoretically and experimentally. Special attention is paid to island formation dimensional variation initial electron velocity and cathode coating resistance. A formula is derived for the optimum grid-to-cathode spacing which yields maximum transconductance, maximum power gain-band product and minimum noise figure.
