Abstract :
We have proposed and analyzed a new millimeter and submillimeter wave transit time device, the bipolar injection and transit time diode (BIPOLITT). The theory and small signal analysis for a two-terminal type rf operation is presented here. The device structure is similar to a heterojunction bipolar transistor (HBT) with an rf floating base. The relatively longer base is utilized to achieve an injection-phase delay close to 180°. The collector depletion region is used as drift region. As an example, a BIPOLITT diode for 300-400 GHz operation is designed, and its small signal specific negative resistance is calculated to be about -3×10-7 Ω·cm2
