Classification: CPC H | IPC H

Claim 15:
16. A wireless device comprising:
an antenna;
a first integrated circuit coupled to the antenna, the first integrated circuit comprising a radio frequency (RF) front end module, the RF front end module comprising:
a transmit path to receive, process and output a transmit RF signal, the transmit path comprising a power amplifier;
a receive path to receive, process and output a receive RF signal, the receive path comprising a low noise amplifier (LNA);
switching circuitry coupled to the transmit path and the receive path; and
a control circuit coupled to the switching circuitry, the control circuit to control the switching circuitry to configure the receive path for operation in one of a plurality of modes;

a filter coupled to the first integrated circuit; and
a second integrated circuit coupled to the first integrated circuit, the second integrated circuit comprising a controller to execute:
one or more first instructions to initialize the first integrated circuit into a first mode having a first relative order of the receive path in which the LNA is coupled to the antenna; and
one or more second instructions to reconfigure the first integrated circuit into a second mode having a second relative order of the receive path in which the filter is coupled to the antenna.
