ABSTRACT:
A high frequency field emission device (200, 400, 500, 600) includes a cathode (210, 410, 563, 610), a field emissive film (260, 460, 560, 660) formed on the cathode (210, 410, 563, 610), an anode (220, 420, 520, 620) spaced from the field emissive film (260, 460, 560, 660), and a control electrode (250, 450, 550, 650, 655) disposed between the anode (220, 420, 520, 620) and cathode (210, 410, 563, 610) for modulating or switching electron emission from the field emissive film (260, 460, 560, 660) according to a high frequency input signal signal.
