High power w-band/f-band schottky diode based frequency multipliers

A multiplier device, comprising:

• a waveguide block comprising an input waveguide, wherein the input waveguide guides an input signal having a frequency;
• and
• a chip connected to the input waveguide, the chip comprising two or more multiplying structures, wherein:
• each of the multiplying structures include:
• an input E-probe structured for receiving the input signal from the input waveguide,
• two or more Schottky diodes,
• one or more stripline based input matching networks structured to transmit the input signal from the input E-probe to the two or more Schottky diodes, to generate output power comprising an output signal having two or three times the frequency of the input signal using the nonlinear properties of the Schottky diodes,
• one or more stripline based output matching networks structured for transmitting the output signal from each of the Schottky diodes to an output E-probe, and
• the output E-probe structured for transmitting a multiplier output, comprising a sum of the output powers generated in each of the Schottky diodes, off the single chip and into an output waveguide.

A method of fabricating a solid-state device, comprising:

• micro-fabricating a chip including diodes, on-chip power combining, and on-chip power distribution, wherein:
• the on-chip power distribution distributes an input power, transmitted onto the chip and having an input frequency, among the diodes,
• the diodes each comprise an anode and a GaAs heterostructure,
• the diodes each generate a higher frequency output through frequency multiplication of the input frequency,
• each of the higher frequency outputs are combined to form a combined output power using the on-chip power combining,
• the anodes are micro-fabricated simultaneously on a same patch of a Gallium Arsenide wafer and under identical conditions, and
• the anodes are balanced in terms of electrical behavior;
• and
• such that the biased device generates the combined output power with an efficiency of at least 30%, the efficiency defined as 100×(combined output power/input power).
