Abstract
A field effect pentode transistor, which provides a gain over an extremely broad band of frequencies is disclosed. The transistor has source and drain electrodes defined by ohmic contacts, a first gate input control electrode defined by a Schottky-barrier, a screen electrode, and a second control gate Schottky-barrier electrode. The screen electrode is an ohmic contact located between the first and second gate control electrodes; and the second control electrode is located between the screen electrode and the drain electrode.
