    Abstract: Transmitter and receiver for wireless communications with improved accuracy and stability in radio frequency control. A transmitter mixes an information-carrying signal (first signal) and a non-modulated wave signal (second signal) with a carrier signal, thereby producing a first and second radio frequency signals for radio wave transmission. A receiver mixes those two radio frequency signals to extract the original information signal. While the received radio frequency signals contain some frequency fluctuations and phase noises that have been introduced at the sending end, such unstable components Δf will cancel out at the receiving end.

    Abstract: A semiconductor module having a built-in antenna element for use in a system of a band of millimeter-waves or quasi-millimeter-waves comprises a substrate, an antenna element, a semiconductor integrated circuit, and a hermetically sealing portion. The antenna element is mounted on one side of the substrate. The semiconductor integrated circuit is also formed on the same side of the substrate as of the antenna element. The semiconductor integrated circuit includes at least either of a transmitter signal processing circuit composed mainly of an amplifier circuit and a frequency converter circuit for processing a signal which is exploited in the system of the band of millimeter-waves or quasi-millimeter-waves and transmitted to the antenna element, and a receiver signal processing circuit composed mainly of an amplifier circuit and a frequency converter circuit for processing a signal which is received by the antenna element and exploited in the system of the band of millimeter-waves or quasi-millimeter-waves. The hermetically sealing portion is designed for hermetically sealing the antenna element and the semiconductor integrated circuit formed on the substrate within a common space defined by a boundary surface or the side of the substrate while the transmissivity of radio waves to the antenna element for the system of the band of millimeter-waves or quasi-millimeter-waves is maintained.

    Abstract: A field effect transistor includes a semiconductor substrate, first and second semiconductor layers formed on the semiconductor substrate, and third semiconductor layers located between the first and second semiconductor layers. The third semiconductor layers have a forbidden band width narrower than those in the first and second semiconductor layers and form a quantum well. The third semiconductor layers include a doping layer such as planar-doping or high doping, and a channel is formed in the third semiconductor layers along the quantum well. The electrons supplied from the doped layer are confined by the quantum well and form a quasi-two-dimensional electron gas.
