Abstract

High efficiency monolithic frequency multipliers have been designed, fabricated, and tested in the W-band. In microwave monolithic integrated circuits (MMICs), transmission lines with various impedances are used not only to transfer the input and output signals, but also to match the impedances of active devices to those of the input and output ports, with open and/or short stubs. Thus, loss in the transmission lines is one of the major limiting factors on circuit efficiencies. This paper presents high-efficiency MMIC frequency doublers with a balanced pair of GaAs Schottky barrier planar diodes operating in the W-band. The geometries of transmission lines were optimized to reduce the loss and thus to improve the efficiency. The demonstrated efficiency of 36.1 % is the highest efficiency reported for a diode-based MMIC frequency multiplier in the W-band.
