Abstract

The invention provides a laminated transformer type power combiner and a series-parallel hybrid power combining structure, and relates to the technical field of power synthesis. The laminated transformer type power combiner disclosed by the invention is similar to a sandwich structure; laminated coils connected with an output end can form an up-and-down laminated wrapping effect on a coil connected to a differential power amplifier, so that the coupling coefficient of the series transformer type power combiner can be effectively improved; the purposes of reducing power synthesis loss and improving power synthesis efficiency are achieved. In the series-parallel hybrid power synthesis structure, through combination of the laminated transformer type power combiner and a T-shaped parallel power combiner, the power synthesis loss is further reduced, and the power synthesis efficiency is further improved. A plurality of groups of coupling line structures with loading capacitors are connected in parallel to form the T-shaped parallel power combiner, parallel power combination and load impedance conversion with a large conversion ratio can be realized in a small area, and the impedance conversion pressure of the series-parallel synthesis structure can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of power combining, in particular to a laminated transformer type power combiner and a series-parallel hybrid power combining structure. Background technique [0002] Power combining technology and coupled line slow-wave impedance transformation structure are widely used in the field of radio frequency or millimeter wave circuits. [0003] In existing transformer-type power combiners, most of the coils adopt a single-layer structure, the coupling coefficient is not high enough, and the serial parasitic resistance of the coils is usually relatively large. At the same time, the power combining efficiency of this type of power combining structure is positively correlated with the coupling coefficient of the transformer, and the relatively low coupling coefficient and relatively large series parasitic resistance hinder the further improvement of the power combining effect. In the traditional hybrid power synthe...
