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.
