摘要： An in-line waveguide divider divides power of an incoming high-frequency signal among openings. Amplification boards disposed on a base are provided for respective openings and are each connected in parallel with one another to the in-line waveguide divider. An in-line waveguide combiner includes openings formed correspondingly to the amplification boards, and is connected to the amplification boards. An electrically conductive amplifier cover includes walls formed to provide isolation between circuits of the amplification boards continuously from the in-line waveguide divider to the in-line waveguide combiner, and the entire surface of the amplification boards at the in-line waveguide combiner side is covered with the electrically conductive amplifier cover except openings and openings. Each of the amplification boards includes a waveguide-to-microstrip transition corresponding to the opening, an amplifier element, and a microstrip-to-waveguide transition corresponding to the opening.

摘要： An output power control device includes: an attenuator to attenuate power of a high-frequency signal output from an oscillator; a high-frequency power amplifier to amplify the power of the high-frequency signal output from the attenuator; a monitor circuit to monitor the power of the high-frequency signal output from the high-frequency power amplifier; and a controller to control an attenuation amount of the attenuator based on the monitor signal output from the monitor circuit or based on attenuation amount setting data from a data unit. The oscillator generates the high-frequency signal in synchronization with a trigger signal. The controller starts control of the attenuation amount of the attenuator based on the attenuation amount setting data, in synchronization with the trigger signal, and, after receiving the monitor signal, the controller controls the attenuation amount of the attenuator based on the monitor signal.

摘要： A waveguide circuit (1) includes a first waveguide tube (10), a second waveguide tube (20), and a third waveguide tube (30). The first waveguide tube (10), the second waveguide tube (20), and the third waveguide tube (30) have cross-sectional shapes to allow propagation of TE modes. The tube axis of the second waveguide tube (20) is parallel to the tube axis of the first waveguide tube (10). One of the narrow sidewalls of the second waveguide tube (20) faces a narrow sidewall (10s) of the first waveguide tube (10). The third waveguide tube (30) includes a coupler that connects a hollow guide of the third waveguide tube (30) to a hollow guide of the first waveguide tube (10) and a hollow guide of the second waveguide tube (20).

摘要： A control circuit (16) is configured to detect the impedance P1 of a load (3) and control each of the reactance value L1 of a first variable reactance element (12), the reactance value L2 of a second variable reactance element (14), and the phase shift amount φ of a phase shifter (15) on the basis of the detected impedance P1. Consequently, impedance matching can be achieved even with the phase shifter (15) that performs discrete phase shift control.

摘要： A coaxial-waveguide-to-hollow-waveguide transition circuit (1) includes a hollow waveguide (10), a coaxial waveguide (20) having an end coupled to a wide wall (16) of the hollow waveguide (10), and a strip conductor (30) located inside the internal path (10h) of the hollow waveguide (10). The coaxial waveguide (20) includes a conducting core wire (22) extending into the internal path (10h) of the hollow waveguide (10). The strip conductor (30) is located so as to make a short-circuit connection between the conducting core wire (22) of the coaxial waveguide (20) and a termination surface (12) of the hollow waveguide (10).

摘要： A transmission module includes n oscillator modules and a phase command signal generator. Each of the oscillator modules includes a voltage controlled oscillator and an amplification circuit. The voltage controlled oscillators output transmission high-frequency signals having the same frequency and synchronized among the n oscillator modules by synchronous control based on a common reference signal. The amplification circuits each perform power amplification for the transmission high-frequency signal from a corresponding one of the voltage controlled oscillators and output the resultant signal. Phases of the transmission high-frequency signals synchronized among the n oscillator modules and output from the voltage controlled oscillators are separately controlled according to respective n phase command signals from the phase command signal generator.
