Abstract: A transceiver (10) for transmitting and receiving satellite RF signals is provided. The transceiver (10) includes RF front-end receiver circuitry (20) capable of receiving FM radio broadcast RF signals and converting the FM radio broadcast RF signals to an intermediate frequency. The RF front-end receiver circuitry (20) is configured to receive RF signals at greater than 108 MHz and convert the RF signals to an intermediate frequency. The transceiver (10) also includes signal processing circuitry (40) including at least one DSP core (42) for demodulating intermediate frequency signals provided by the front-end circuitry (20) and for modulating data to be transmitted into baseband modulated data signals, and at least one audio output (46). The transceiver (10) further includes RF transmitter circuitry (30) configured to convert the baseband modulated data signals provided by the at least one DSP core (42) into modulated transmit signals having a frequency greater than 108 MHz for transmission and transmit the modulated transmit signals.
