Abstract
A frequency multiplier in which one or more varactors each include arrays of Schottky barrier diodes combined in rows of parallel-connected diodes and columns of series-connected diodes. The arrays are dispersed on a thermal substrate, or confined to a GaAs strip guide on a suitable substrate and in either case employed in various discrete-component or integrated circuit transmissions systems. These series-parallel arrays can be increased in size as desired for power handling capabilities or thermal dissipation and provide readily selectable impedance levels and breakdown voltages. These properties make the frequency multipliers useful in microwave and millimeter-wave systems, including those requiring high-power transmitters.
Claims10
A frequency multiplier comprising:
- a plurality of rows of varactor diodes, each row having a plurality of varactor diodes connected in parallel;
- and
- means for providing a plurality of columns of the varactor diodes, comprising means for aligning and connecting respective varactor diodes of each row in series,
- an array of varactor diodes thereby being formed.
A frequency multiplier for multiplying a first microwave signal having a first frequency, comprising
- a waveguiding structure for transmitting electromagnetic energy of the first frequency;
- a plurality of rows of varactor diodes coupled to said waveguiding structure, each row having a plurality of varactor diodes connected in parallel;
- and
- means for providing a plurality of columns of the varactor diodes, each column having a plurality of varactor diodes, comprising means for aligning and connecting respective varactor diodes of each row in series,
- an array of varactor diodes thereby being coupled to the waveguiding structure.
