Abstract
A high-frequency oscillator is provided, which decreases the phase noise and which has excellent mass productivity and reproducibility. This oscillator is comprised of (a) first, second, and third FETs formed on a substrate; (b) a first transmission line formed on the substrate; the first line being connected to drains of the first and second FETs formed on the substrate; (c) a second transmission line formed on the substrate; the second line being connected to gates of the first and second FETs; (d) a third transmission line formed on the substrate; the third line being connected to sources of the first and second FETs; (e) a fourth transmission line formed on the substrate; the fourth line being connected to the drain of the second FET and a drain of the third FET; (f) a fifth transmission line formed on the substrate; the fifth line being connected to the gate of the second FET and a gate of the third FET; and (g) a sixth transmission line formed on the substrate; the sixth line being connected to the source of the second FET and a source of the third FET. The first, second, and third transmission lines are coupled together due to electromagnetic field, and the fourth, fifth, and sixth transmission lines are coupled together due to electromagnetic field.
