Abstract
A TX/RX RF switch that may include a reception path; and a transmission path that has an antenna port, a transmission input port, and transmission transistors. The transmission transistors have source-bulk connections. The reception path has an antenna port, a reception output port, and reception transistors. The reception path includes a first reception transistor that is closest to the antenna port, out of the reception transistors, and has a source-bulk connection, and at least one other reception transistor that has a bulk-to-ground connection. The reception transistors and the transmission transistors are CMOS transistors.
