Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] Such as figure 2 , 3 As shown, the stripline 90° hybrid joint according to the present invention includes two layers of parallel signal transmission lines, the signal transmission line at the bottom layer is a straight-through signal line, and the two ends of the straight-through signal line are respectively the input end and the stripline 90° hybrid joint. The straight-through end, the upper signal transmission line is a coupled line, and the two ends of the coupled signal line are striplines. The 90° hybrid connector is the coupled end and the isolated end. Such as Figure 4 , 5 As shown, the straight-through signal line and the coupled signal line are routed in a serpentine shape, and the distance between two adjacent single-branch lines is equal to twice the line width of the signal transmission line.

[0023] When the circuit design is completed, the p...

Abstract

The invention belongs to the technical field of 90° hybrid joints, and discloses a stripline 90° hybrid joint. The stripline 90° hybrid joint of the present invention includes two layers of parallel signal transmission lines, the bottom signal transmission line is a straight-through signal line, and the two ends of the straight-through signal line are respectively the input end and the straight-through end of the stripline 90° hybrid joint, and the upper layer signal The transmission line is a coupled line, and the two ends of the coupled signal line are striplines. The 90° hybrid connector is the coupled end and the isolated end; the straight-through signal line and the coupled signal line adopt serpentine routing, and the distance between two adjacent single-branch wires is equal to 2 times the width of the signal transmission line. The volume of the invention is small, the proportion of length and width is appropriate, the invention is more solid and reliable.

Description

technical field [0001] The invention relates to the technical field of 90° hybrid joints, in particular to a stripline 90° hybrid joint. Background technique [0002] The 90° hybrid connector is a four-port passive circuit that is often used for power distribution and synthesis of RF signals. When used for power distribution, the signal is input from the input terminal, output from the through terminal and coupled terminal, and the isolation terminal is connected to the load. When used as a power combiner, the signal is input from the input terminal and the isolation terminal, output from the coupled terminal, and directly connected to the load. A typical power combining amplifier circuit such as figure 1 As shown, the 90° hybrid connector divides one signal into two signals with the same amplitude and orthogonal phase before power amplification, and enters their respective power amplifiers respectively. The amplified two signals then enter the 90° hybrid connector to synt...
