All the devices tended to oscillate, although the available theory predicted a stable behavior. An investigation was started to determine whether higher order modes were responsible for the unstable behavior. In the meantime, a new design was carried out with Schottky-barrier input and output gates, and a new rf test fixture was fabricated and tested. Theoretical investigations of the dc field distribution along the device and the input-output impedance along the device was carried out. Author
