Gallium arsenide Schottky barrier doubler diodes for millimeter wavelength application
Abstract
The problem of obtaining local oscillator power for mixing purposes in the millimeter and submillimeter ranges is addressed. Attention is given to an approach that involves the use of oscillators of higher reliability and lower frequency together with a harmonic generator diode to supply local oscillator power in the frequency range greater than 100 GHz. The harmonic generator diode here is typically an n-type GaAs Schottky barrier varactor device. The design and fabrication of such devices are discussed, as are results yielding conversion efficiencies on the order of 10% in the case of a broadband frequency doubler with output ranging from 110 to 170 GHz and as high as 20% for a narrowband doubler at 145 GHz. These results are thought to be the best attained in the respective frequency ranges to date.
