Abstract

An oscillator scheme that substantially increases the millimeter-wave power generation capabilities of the quantum-well resonant tunneling diode (RTD) by device-level series integration is analyzed. A series-integrated RTD including the transit time effect has been simulated in great detail at millimeter-wave frequencies. Using the available experimental characteristics of a GaAs/AlAs quantum-well RTD, the simulation shows that 120-mW output power with 10% DC-to-RF conversion efficiency at a 5- Omega load can be obtained at 100 GHz when ten such RTDs are integrated in series. >
