摘要： A high frequency amplifier circuit comprises an amplitude characteristic correction circuit and a phase characteristic correction circuit for compensating the non-linearity of the input-output characteristics of the amplifier. The amplitude characteristic correction circuit varies the drain voltage or the collector voltage of the amplifier in accordance with the envelope level of an input signal in such a manner that the relationship between the amplitude of the output of the amplifier and the amplitude of the input signal has linearity. On the other hand, the phase characteristic correction circuit provides a quantity of phase shift to the input signal in accordance with the envelope level of the input signal, and the phase-shifted input signal is applied to the amplifier in such a manner that the phase of the output of the amplifier and that of the input signal coincide with each other.

摘要： A piezoelectric thin-film acoustic wave device formed of a piezoelectric thin film of AlN on the +C plane and having the polarization strength of not lower than 0.63×10−20 F/V and an information processing unit using the same are disclosed. This is the result of the inventors having studied the factors other than the C-axis orientation affecting the electromechanical coupling factor and developing a method of improving the electromechanical coupling factor in view of the occasional fact that the electromechanical coupling factor cannot be improved by improving the C-axis orientation and the electromechanical coupling factor required for the piezoelectric thin-film acoustic wave device is not obtained. In such a case, the receiving sensitivity of the receiving system may be deteriorated and the transmission strength of the transmission system is required to be increased undesirably having an adverse effect on the power saving efforts.

摘要： A method and apparatus for controlling an antenna and a tracking antenna system using them. A rate sensor detects the angular rate of the vehicle turning. On the basis of the detected value, an error correction circuit determines the steering angle of the antenna. If it is judged from the determined angle that the vehicle is not turning or only slightly turning, a motor driving circuit suspends driving of a motor and at the same time a linear actuator locks a major gear. If it is judged that an accumulated error of a control target which is determined on the basis of the output of the rate sensor is not negligible, the error correction circuit starts a closed-loop control on the basis of a receiving signal level. In such a manner, the power consumption in the motor can be reduced.

摘要： An amplifier circuit suitable for use in various types of communication devices, radar systems and the like, wherein a fundamental-wave signal extracted from an input side is converted into a second order signal and the second order signal is shifted so as to be opposite in phase and equal in amplitude to a second order signal produced by an amplifier such as an FET or multistage operational amplifier. The phase shifted signal is applied to the amplifier output, whereby the second order signal produced by the amplifier can assuredly be equivalently short-circuited and the operation efficiency of the amplifier can be improved.

摘要： The present invention provides a high-frequency switch including: a first switching element connected between a first input/output terminal and a second input/output terminal; a second switching element connected between the second input/output terminal and the first switching element; a high-frequency line provided between the first input/output terminal, the first switching element, and a third input/output terminal; and a third switching element connected between the third input/output terminal, the high-frequency line, and a ground. By connecting the first switching element, the second switching element, the high-frequency line, and the third switching element, because there exists no FET through which a large current flows when a state between the first input/output terminal and the third input/output terminal is set to a transmission state which requires high power handling capability, there is no need to use an FET having a large gate width, which is effective in reducing a loss of the switch.
