摘要： 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.

摘要： A harmonic mixer comprising an anti-parallel diode having two diodes connected in parallel in reverse directions between first and second ends, the first end receiving a local oscillation signal, and the second end receiving an information signal and a DC bias, an output signal of the harmonic mixer being available at the second end. With the capabilities of the anti-parallel diode, it is possible to realize the radio communication with the use of a high frequency range at least 30 GHz at a low cost and with a simple configuration of the harmonic mixer and the radio communication device having the same, although it is considered hard to generate the stable local oscillation frequency for the radio communication of at least 30 GHz.

摘要： 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.

摘要： A semiconductor module having a compact antenna element capable of providing desired directivity therein has been disclosed. When an electromagnetic-wave radiation window has the capability of a lens, directivity can be set arbitrarily. For improving directivity, a convergent lens for converging millimeter waves or quasi millimeter waves is employed. For impairing directivity, a divergent lens is employed. In the case of the convergent lens, a direction in which radio waves are radiated or received by the antenna element can be set by deviating the center axis of the lens from the center of the antenna element.
