Abstract

The invention provides an E-band waveguide E-T branch and multi-probe coupling structure power synthesis amplifier. A two-stage cascaded waveguide E-T branch is used to realize the division of an input E-band millimeter wave signal into four paths of signals transmitted in a waveguide, the four paths of signals are converted from a waveguide transmission mode to a four-path microstrip transmissionmode via a waveguide multi-probe transition structure, a power distribution structure converts a signal inputted by a rectangular waveguide into 16 paths of signals of the same amplitude and phase with a transmission and the microstrip circuit, the signals are subjected to power amplification, the 16 paths of microstrip transmission mode signals which are subjected to power amplification are synthesized to be one path of high-power millimeter wave signal through the waveguide multi-probe transition structure and a waveguide E-T branch structure and the signal is outputted out of the waveguide, the multiple-path high-efficiency power synthesis amplification of a millimeter wave power synthesis amplifier is achieved, and the high-power output of an E-band signal is achieved.

Description

technical field [0001] The invention relates to a power amplifier, in particular to an E-band waveguide E-T branch and multi-probe coupling structure power synthesis amplifier. Background technique [0002] With the wide application of millimeter wave technology in the fields of radar, guidance and communication, higher and higher requirements are put forward for the bandwidth, gain and output power of the millimeter wave signal source. Although the millimeter-wave solid-state power amplifier chip has the advantages of small size, light weight, high reliability, and compact circuit structure, the output power of a single solid-state device is affected by the physical characteristics of its own semiconductor and the problems of heat dissipation, processing technology, and impedance matching. However, it is far from reaching the output power required in the actual project, so it cannot meet the requirements of the millimeter wave high-power communication system. Therefore, wh...
