Abstract :
A monolithic planar array containing thousands of GaAs barrier-intrinsic-n/sup +/ diodes have produced 1-W output power at 100 GHz in a tripler configuration. Tripling efficiency of 8.5% has been obtained from approximately 4-mW incident power on each diode, in excellent agreement with the predictions of large-signal nonlinear circuit analysis of frequency multiplication. The device performance is limited by the parameters of the fabricated diodes. Significant improvement is expected with realizable diode parameters and optimized pumping condition.<>
