Abstract

Provided are an interstage matching circuit and a push-pull power amplifier circuit. The push-pull power amplifier circuit comprises a pre-stage push-pull amplifier circuit and a post-stage push-pull amplifier circuit. The interstage matching circuit comprises a first matching capacitor connected in series between the pre-stage push-pull amplifier circuit and the post-stage push-pull amplifier circuit; and a second matching capacitor connected in series between the pre-stage push-pull amplifier circuit and the post-stage push-pull amplifier circuit; a first matching inductor is connected with a connection node between the pre-stage push-pull amplifier circuit and the first matching capacitor, the first matching inductor is connected with a second matching inductor, the second matching inductor is connected with a connection node between the pre-stage push-pull amplifier circuit and the second matching capacitor, and a connection node between the first matching inductor and the second matching inductor is used for connecting with a feed power supply.
