    摘要： An RF power amplifier has a final-stage amplifier stage which generates an RF transmit output signal, a signal detector which detects an RF transmit output level, a first detector, a second detector and a control circuit. The final-stage amplifier stage includes a transistor and a load element and performs saturation type nonlinear amplification and non-saturation type linear amplification. The first detector and the control circuit maintain the RF transmit output signal approximately constant with respect to a variation in load at an antenna at the saturation type nonlinear amplification. The second detector and the control circuit reduce an increase in the output voltage of the final stage transistor with respect to an overload state of the antenna at the non-saturation type linear amplification.

    摘要： The most important task in realizing a downsized and low cost THz band spectroscopic and fluoroscopic instrument is to achieve downsizing and cost reduction of oscillators used in the instrument. A metal base transistor is used for an active element of the oscillator. In order to improve the maximum oscillation frequency of the transistor to several THZ, InN having a high electron saturation velocity or a material mainly composed of InN is used for a collector layer. In order to obtain characteristics with excellent reproducibility, it is useful to insert InGaN into an interface between the collector layer and the base layer. Using the metal base transistor of the present invention makes it possible to constitute an oscillator allowing a THz band oscillation. Further, the present invention provides a spectroscopic instrument applying this oscillator to at least one of a signal source and a local oscillator.

    摘要： The present invention provides a radio frequency power amplifier which may not introduce radio frequency loss during switching power amplifier units between high and low output power levels. By connecting a first-stage matching network M12 and first-stage matching network M13 to respective output nodes of a power amplifier unit A11 and power amplifier unit A12 that either one operate by switching, connecting the output nodes of the first-stage matching network M12 and M13 in parallel, connecting a last-stage matching network M11 between the junction of M12 and M13 and the output terminal OUT, the first-stage matching networks M12, M13, and last-stage matching network M11 are formed, for both power amplifier units A11 and A12, so that impedance matching is established between the output terminal OUT and the power amplifier unit in operation when one unit is in operation the other is in stop of operation. The present invention allows switching from one power amplifier unit to the other without the need of a radio frequency switch.

    摘要： To provide a high frequency amplifying apparatus for reducing a phase change caused in switching to a different output level, a variable phase shifter is provided at at least one location of respective paths rearward from a branching circuit for switching a path on a high output side having an amplifier using a first semiconductor device at an output stage and a path on a low output side having an amplifier using a second semiconductor device with a smaller output than the first semiconductor device on an output stage in accordance with a desired output level. After branching and a phase length of the variable phase shifter is set to a pre-determined value such that passing phase lengths of the respective paths become substantially the same by passing either of the paths.
