Abstract

A millimeter-wave single-chip integrated transmission power distribution circuit relates to the field of circuit technology and solves the technical problems of reducing occupied area, parasitic effects and power consumption. The circuit includes a three-way power divider, a first-stage drive amplifier, a second-stage drive amplifier, a power amplifier, a frequency divider, and a polyphase filter for generating four-way quadrature differential signals; the one-point The source signal input terminal of the three-way power splitter is connected to the output end of the first-stage drive amplifier, and the first output end of the one-point three-way power divider is connected to the input end of the polyphase filter through the second-stage drive amplifier. The second output terminal of the three-way power divider is connected to the input terminal of the power amplifier, and the third output terminal of the three-way power divider is connected to the source signal input terminal of the frequency divider. The circuit provided by the invention reduces the parasitic effect, occupies a small chip area, and has low power consumption.

Description

technical field [0001] The invention relates to circuit technology, in particular to a technology of a millimeter-wave monolithic integrated transmission power distribution circuit. Background technique [0002] Due to the high available bandwidth and high detection accuracy of the millimeter-wave frequency band, millimeter-wave chips are widely used in wireless communication, radar, guidance, remote sensing technology, radio astronomy, and electronic countermeasures. In recent years, with the successive opening of millimeter-wave frequency bands, millimeter-wave chips have become a hot spot. Among them, the millimeter-wave RF front-end, as a key technology, largely determines the performance, cost, and size of the system. [0003] In recent years, with the increasing market demand for millimeter-wave chips, the requirements for their cost, integration, and power consumption have increased. The advancement of integrated circuit technology, especially CMOS technology, makes...
