Antenna sharing for radio frequency signals in same frequency bands

A method for receiving a composite signal using an antenna, the method comprising:

• determining a first switch setting for a first portion of the composite signal;
• amplifying the composite signal using the first switch setting to obtain a first receiver input signal;
• decoding a first signal from the first receiver input signal using a first receiver;
• determining a second switch setting for a second portion of the composite signal;
• amplifying the composite signal using the second switch setting to obtain a second receiver input signal;
• and
• decoding a second signal from the second receiver input signal using a second receiver.

An apparatus for receiving a composite signal using a single antenna, comprising:

• means for determining a first switch setting for a first portion of the composite signal;
• means for amplifying the composite signal using the first switch setting to obtain a first receiver input signal;
• means for decoding a first signal from the first receiver input signal;
• means for determining a second switch setting for a second portion of the composite signal;
• means for amplifying the composite signal using the second switch setting to obtain a second receiver input signal;
• and
• means for decoding a second signal from the second receiver input signal.

An integrated circuit for receiving composite signals comprising:

• a first amplifier coupled to an antenna;
• a second amplifier coupled to the antenna;
• a first receiver;
• a second receiver;
• a first programmable switch, wherein the first programmable switch couples the first receiver to the output of either the first amplifier or the second amplifier;
• and
• a second programmable switch, wherein the second programmable switch couples the second receiver to the output of either the first amplifier or the second amplifier.
