1. A radio frequency switch circuit structure comprising:
an RF1-st input terminal;
an RF2-nd input terminal;
an RFA-th output terminal;
an RFB-th output terminal;
an RFC-th output terminal;
a P1A-th path comprising a first terminal coupled to the RF1-st input terminal, and a second terminal coupled to the RFA-th output terminal;
a P2A-th path comprising a first terminal, and a second terminal coupled to the RFA-th output terminal;
a P1B-th path comprising a first terminal, and a second terminal coupled to the RFB-th output terminal;
a PIC-th path comprising a first terminal, and a second terminal coupled to the RFC-th output terminal;
a first common path coupled to the RF2-nd input terminal and the first terminal of the P2A-th path; and
a second common path coupled to the RF1-st input terminal, the first terminal of the P1B-th path, and the first terminal of the PIC-th path;
wherein the first common path and the second common path cross each other on different planes to form a first crossover;
the P1A-th path does not form a crossover with any common path or any path of the switch circuit structure; and
the P2A-th path and the P1B-th path are not coupled to each other.
