Abstract

The invention discloses a broadband millimeter wave hybrid waveguide magic T power divider / synthesizer, and relates to the technical field of millimeter wave communication equipment and radio amplifiers. According to the technical scheme, wedge-shaped fin lines connected through a thin-film resistor and a trapezoidal cup base probe located in an inverted-Y-shaped opening seam in a dielectric substrate are embedded in a rectangular cavity of an isolation waveguide, the thin-film resistor is etched on the dielectric substrate through a thin-film technology, and the trapezoidal cup base probe is located in a slot between the two symmetrical waveguide matching column step bodies, and is integrally matched and integrated into a magic T isolation branch; and a radio frequency signal is input into a standard rectangular main waveguide through an input standard rectangular waveguide port, is divided into a left signal and a right signal through a matching structure formed by the trapezoidal cup base probe fixed between the two matching steps, enters the height reduction rectangular branch waveguide, and outputs the radio frequency signal through an output standard rectangular waveguide port.

Description

technical field [0001] The invention relates to a broadband millimeter wave hybrid waveguide magic T power divider / synthesizer mainly used in the technical field of millimeter wave communication equipment and radio amplifiers in the field of microwave communication technology. Background technique [0002] In recent years, with the rapid development of satellite communication technology, the communication frequency band has expanded from the commonly used Ka frequency band to the higher QV frequency band. As a radio frequency signal amplifier, the millimeter wave power amplifier plays an important role in the uplink transmission link of the millimeter wave communication system. effect. With the development and maturity of the third-generation semiconductor technology, the single-chip output power of the power amplifier chip is also increasing, but it is still unable to meet the needs of hundreds of watts and kilowatts of high-power power amplifiers in the fields of millimete...
