  • LOW POWER FM TRANSMITTER
    Publication number: 20110007843
    Abstract: An FM transmitter operates at low power by maintaining a substantially constant transmit voltage over the FM frequency band. A transmit signal strength indicator (TSSI) is provided at the output of the FM transmitter to measure the power at the output of the power amplifier. The TSSI generates a power control signal indicative of the output power and inputs the power control signal to the baseband processor. The baseband processor generates gain control signals to control the gain of various analog stages of the FM transmitter based on the power control signal.
