Abstract :
It has been demonstrated that a current-limiting cathode contact can be used to improve the performance of relatively thick vapour eptaxial InP transferred-electron devices. A peak power of 120 W with 18% efficiency at 5 GHz has been obtained from 34 ¿m-thick active-layer devices with silver tin-alloy metal contacts.
