Methods and systems for optimizing an FM transmitter and FM receiver in a single chip FM transmitter and receiver are disclosed and may include receiving an FM signal from each of multiple selected antenna configurations. The received signal strength obtained for each configuration may be measured and stored in a memory, and FM signals may be transmitted and/or received utilizing a configuration that generates a received signal strength above a desired threshold from the measurement. The FM transmitter and receiver may be integrated on-chip, and may be impedance matched to the antennas utilizing selectable capacitors integrated on-chip and/or off-chip and selectable inductors located off-chip. The multiple antennas may comprise antennas that are internal and antennas that are external to the wireless device, each of which may be tuned for one or more wireless protocols. One or more of the antennas may comprise metal components within the wireless device.
