Abstract

In order to overcome the defects that the linearity of the large-power semiconductor amplifier is hard to meet the requirement of a communication system, the output harmonic wave is high and an additional filter is needed, the invention provides an amplifier design of a B-type push-pull amplifier by utilizing a space combination structure. The amplifier has the advantages that the linearity is good, the output power is high and the volume is small. In the amplifier, the barons of two paths of signals with same amplitudes and different phases generated by need of the B-type push-pull amplifier are integrated in an antenna for space combination, so that the miniaturization of the system is realized. The invention adopts the specific scheme for solving the technical problems that a fine line antenna in the space combination structure is utilized to form the baron with two-way output and 180-degree phase shifting, a B-type push-pull amplifier unit is formed by the same input and output of the barons, a B-type push-pull amplifier unit array is effectively combined by the space combination structure, so that the large-power output can be realized, and simultaneously good linearity and high efficiency are ensured.

Description

Technical field [0001] The patent of the present invention relates to a design technology of a highly linear power amplifier using space synthesis technology, which can be widely used in communication systems such as satellite communication and microwave and millimeter wave communication. Background technique [0002] Microwave and millimeter wave amplifiers are one of the key devices in the field of communication. At present, vacuum tube amplifiers are widely used in the field of high-power amplifiers. However, due to the limited life of vacuum tube devices and the need to use high voltages, the operation hazards increased. More importantly, the linearity of the vacuum tube amplifier is poor, and it usually needs to retreat more than 6dB from the nominal output power to meet the linearity requirement. [0003] The lifetime of the semiconductor amplifier is much longer than that of the vacuum tube device, and it has the advantages of low operating voltage. However, due to ...
