Miniature power gain balancer based on dual-mode resonator

The invention discloses a miniature power gain balancer based on a dual-mode resonator. The miniature power gain balancer includes a micro-strip layer, a medium layer and a metal layer which are stacked in sequence from top to bottom. The micro-strip layer includes a transmission line main line, a first resistor, a second resistor and a third resistor, the first resistor, the second resistor and the third resistor are connected sequentially on the transmission line main line, and the micro-strip layer also includes a first dual-mode resonator surface layer micro-strip, a second dual-mode resonator surface layer micro-strip and a third dual-mode resonator surface layer micro-strip which are connected with the first resistor, the second resistor and the third resistor respectively. The miniature power gain balance provided by the invention has the advantages of small size, large equilibrium quantity and small insertion loss, and is particularly suitable for flatness adjustment of a high power source gain balancer which works in a low frequency band.
