    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: A high-frequency power amplifier comprises a pair of FETs, a divider which supplies opposite-phase versions of a signal to be amplified to the FETs, distributed-parameter transmission lines connected respectively at one ends thereof to output electrodes of the FETs, and a combiner which combines signals appearing at another ends of the transmission lines into a signal of a common phase. Stubs which short-circuit for even harmonics included in output signals of the FETs are connected respectively to the transmission lines at positions distant from the output electrodes of the FETs by a multiple of a quarter wavelength of the fundamental wave included in the output signals of the FETs. A first capacitor is connected between the transmission lines at positions distant from the output electrodes of the FETs by the 1/12 wavelength of the fundamental wave included in the output signals of the FETs so that the output electrodes of the FETs are open for the third harmonic, and a second capacitor is connected between the transmission lines at positions between the connecting positions of the first capacitor and the connecting positions of the stubs so as to perform impedance matching for the fundamental wave included in the output signals of the FETs.

    摘要: A vehicle speed sensing device comprises a Doppler radar unit for producing a Doppler signal related to the vehicle speed and producing a speed signal from the Doppler signal, a first section for extracting noise components in the Doppler signal and producing a noise detection signal, and a second section for producing an output signal of the vehicle sensing device. The device output is the speed signal from the Doppler radar unit when the noise detection signal is absent while the device output is null or a speed signal having an amplitude identical with that of the speed signal just before the appearance of the noise detection signal when the noise detection signal is present.
