摘要： A radio-frequency amplifier circuit of simple construction having low power consumption and low heat generation, and which amplifies an input signal while maintaining composite triple beat (CTB) distortion, amplitude type cross modulation distortion, and phase type cross modulation distortion at a minimum, is provided. The radio-frequency amplifier comprises a transformer which transforms an input signal from an unbalanced state to a balanced state. The amplifier further comprises at least one distortion generation circuit including a first circuit having a nonlinear element and a first delay line coupled in series, and a second circuit having an attenuation element and a second delay line coupled in series. The first and second circuits are coupled in parallel. At least one distortion generation circuit is coupled to an input, an output, and/or an intermediate point of a radio-frequency amplification stage of the radio-frequency amplifier. The first and second delay lines are configured to create a delay time change in a signal input level of a signal input to the radio-frequency amplification stage which opposes a delay time change in the signal input level caused by a delay time difference between the input and output of the radio-frequency amplification stage. A transformer transforms the amplified input signal from the balanced state back to an unbalanced state before outputting the amplified signal from the amplifier circuit.

摘要： A planar microstrip array antenna with a beam tilt, which comprises a plurality of pairs of circularly polarized wave radiating elements (63a, 63b), the orientation angles of the two radiating elements in each pair being different by a predetermined angle within the plane of the planar antenna. The antenna further comprises a feed line (51) for supplying electric power to the radiating elements (63a, 63b). The feed line is provided with a plurality of pairs of terminal feeding portions (53a, 53b) which diverge corresponding individually to the pairs of circularly polarized wave radiating elements. The paired feeding portions are equal in electrical length. Since the respective orientation angles of the paired radiating elements (63a, 63b) are different, a phase difference is produced between the radiating elements, thus providing a beam tilt. Since no phase shift portion for producing a phase difference is formed between the paired terminal feeding portions (53a, 53b), the configuration of the feed line is simple.
