Abstract:
In this work, we present a novel concept for power-combined high-power frequency multipliers consisting of four multiplying structures integrated on a single-chip with the input and output waveguides perpendicular to the waveguide channels, where the diodes are located, by using silicon micromaching techniques. The input power is equally divided in-phase by four E-probes located at the input waveguide. The produced output power is recombined at the output using the same concept. A 1.6 THz tripler has been designed using this architecture. The expected conversion efficiency of the tripler is ~ 2-3 % efficiency over a ~ 20 % bandwidth for a 32 mW of total input pump power.
