Integrated-circuit phase-lock oscillators are extremely difficult to develop above 60 GHz because of circuit losses. A viable alternative is to use a frequency doubler. A Q-to-W-band (40 to 80 GHz) frequency doubler has been developed using integrated-circuit suspended stripline. A conversion loss of less than 6.5 dB has been achieved with the output frequency at 80 GHz. This high efficiency was obtained by an innovative input and output matching circuit design. The advantages over a waveguide doubler include large reductions in size, weight and cost.
