    摘要: The present invention relates to a microwave/millimeter wave sensor apparatus that can obtain highly-sensitive sensing information, while being a simple structure, being inexpensive, and having high power efficiency. In the microwave/millimeter wave sensor apparatus according to this invention, a planar radiation type oscillator substrate (S1) having an inner-layer GND (12) interposed between a front surface side dielectric substrate (10) and a rear surface side dielectric substrate (11) has a pair of conductor patches (4, 4) in an axis-symmetric manner on the side of the front surface layer (16). A gate (2) and a drain (3) of a microwave transistor (1) are respectively connected to the conductor patches (4, 4) to supply power to the gate (2) and the drain (3) of the microwave transistor (1) through a gate-side RF choke circuit (5a) and a drain-side RF choke circuit (5b). An impedance line (9) satisfying an oscillation condition is connected to a source (8) and a transmit RF signal in an RF zone as a planar radiation type oscillator is transmitted and a receive RF signal as reflected waves is received from a measured object, thus obtaining an IF signal as the sensing information through homodyne mixing.

    摘要: The invention relates to a microwave pulse generator for generating microwave pulses with nanosecond pulse duration, comprising a pulse generator generating control pulses of a constant pulse width and a microwave oscillator generating microwave oscillations. The microwave oscillator is fitted with a transistor amplifier, to which a frequency-determining resonant circuit and an ohmic device for reducing the resonant circuit sharpness are connected in such a way that a control pulse of the pulse generator guided to the transistor amplifier on an input binder leads to a tappable microwave oscillation on an output binder of the microwave oscillator, which follows at least approximately the trajectory of the control pulse.

    摘要: In a frequency multiplier (31) constructed to input an input signal to a transistor (32) through an input matching circuit (33) and output a multiplied output signal outputted from the transistor (32) through a reflecting type fundamental wave signal band suppressing circuit (41) and an output matching circuit (42), a transmission line (40) for producing a standing wave is disposed between the output terminal of the transistor (32) and the input terminal of the reflecting type fundamental wave signal band suppressing circuit (41). Because the voltage acting on the output terminal of the transistor (32) consequently increases, the transistor (32) operates at a point at which the nonlinearity of its input-output characteristic is greater and the output power of the multiplied output signal increases.
