摘要： According to one embodiment, a power detector includes a reference voltage generator, a square signal generator, a detection circuit, and an output circuit. The reference voltage generator is configured to receive a bias voltage and generate a reference voltage. The square signal generator is configured to receive a voltage having a high frequency input voltage superimposed on the bias voltage and output a signal including the reference voltage, a voltage of a square of the high frequency input voltage, and a high-frequency signal. The detection circuit has a first lowpass filter, a first operational amplifier configured to amplify error between an output voltage of the first lowpass filter and the reference voltage and output the error as a control voltage, and a feedback transistor configured to feed a feedback current according to the control voltage back to an output terminal of the square signal generator.

摘要： A high-gain monolithic antenna with high freedom of design has a signal circuit and a stripline dipole antenna which are provided on a substrate. A dielectric film and a conductor cover covering the dielectric film are provided on the upper surface of the substrate, in addition to a hole extending vertically downward to the underside of the substrate, a conductor wall being provided on the surface thereof. Furthermore, a metallic film is evaporated so as to contact both a metallic cover and a conductor wall. A first grounding conductor and a dielectric are provided on the lower surface of the substrate, and a second grounding conductor is provided on the upper surface of the substrate. A horn, which is tapered into the dielectric and the first grounding conductor thereby forming the shape of a quadrangular pyramid, is provided so as to overlap a hole etched into the substrate. Microwaves or milliwaves are radiated to/from the horn to/from the underside of the substrate.
