A high-frequency circuit device includes a substrate and a high-frequency circuit. The high-frequency circuit is provided on the substrate and has a signal line. The signal line is configured with a slot line provided by electrodes that are arranged side-by-side with a space therebetween on the substrate. The slot line can facilitates circuit design compared to a microstrip line and has significantly low conduction loss compared to a coplanar line, and can improve the Q-value of the high frequency circuit. This can provide an improved high-frequency circuit device having small phase noise. The high-frequency circuit device, which also serves as an oscillator, employs a slot output and thus can provide an advantage of better continuity for a class-B push-pull amplifier that operates more efficiently than a class-A one.
