A second antenna port is electrically connectable or connected to the signal path. An antenna termination circuit is electrically connected to the first antenna switch. The antenna termination includes an impedance element. The first antenna switch electrically connects the first antenna port to the antenna termination circuit when the signal path is electrically connected to the second antenna port.
