This ALMA memo, also published as a dissertation at the University of Virginia in January 2003 (UVA Science & Engineering Library call number Diss. Engr. 2003.S24), presents a novel GaAs on Quartz based approach toward larger band-width Schottky diode frequency multipliers and reports the first fully integrable frequency multiplier based on this composite substrate is reported. This technology was developed as a low cost solution for meeting the ALMA frequency multiplier requirement up to about 400 GHz. This technology has since then been commercially applied to design and build frequency triplers for the first local oscillator chains for ALMA bands 6 and 7. The memo also describes other contemporary state-of-the-art frequency multiplier technologies and provides a comprehensive up to date survey of existing frequency multiplier designs together with their measured
performances from published literature.
