Claim 12:
13. An antenna circuit switching method comprising:
providing an antenna switch circuit comprising:
an antenna port;
a termination port;
a receive port;
a first switch coupled between the antenna port and the termination port;
a resonant inductance having a first terminal connected to the receive port and a second terminal connected to a node located between the antenna port and the first switch;
a second switch coupled between a reference potential and a node located between the resonant inductance and the receive port; and
a series coupled capacitance and third switch that are coupled in parallel with the resonant inductance; and

switching the antenna switch circuit between:
a transmit mode in which each of the first switch, the second switch, and the third switch are in an on state; and

a receive mode in which each of the first switch, the second switch, and the third switch are in an off state.
