    摘要： A microwave multi-stage power amplifier has matching circuits for input and output stages and one or more inter-stage matching circuits. The amplifier and a signal output pad and first and second voltage supply pads are formed at one and the same semi-insulating substrate. A first FET in the output stage has its drain connected to the first voltage supply pad through a first distributed line and further connected to the signal output pad through a second distributed line in which the first and second distributed lines contribute to formation of the matching circuit for the output stage. A second FET in a stage preceding to the output stage has its drain connected to the second voltage supply pad through a third distributed line serving as a connection conductor. The first distributed line has a width larger than that of the third distributed line and has a length which limits an impedance seen at the drain of the output stage FET towards the first voltage supply pad at an operation frequency of the amplifier to a value other than infinity.

    摘要： Provided is a multi-function radar apparatus capable of measuring both a distance to a target object and a temperature of the target object with high accuracy. A transmission signal produced from a high-frequency signal generating unit (9) is amplified by a transmission signal amplifying unit (12) while intermittently stopped by a transmission intermittent stop switch (11), and is emitted to a target object (13) via a circulator unit (2). A reflected wave from the target object (13) is input as a reception signal to a transmitting and receiving antenna (1) while the transmission signal is emitted, and a radiated wave from the target object (13) is input as the reception signal thereto while the transmission signal is not emitted. The reception signal is amplified by a reception signal amplifying unit (3) via the circulator unit (2), and is mixed by a frequency converting unit (4) with the transmission signal branched by a high-frequency signal branching unit (10) to thereby generate a beat signal. A signal processing unit (6) calculates the distance to the target object (13) and the temperature of the target object (13) based on the beat signal amplified by a beat signal amplifying unit (5).
