Patent ID: 7155179

Claim:
A transceiver having self-jamming immunization, comprising: a microprocessor; a transmitter coupled to said microprocessor, said transmitter comprising one or more signal generators having frequencies that are controlled by frequency data from said microprocessor for setting a TX center frequency and for transmitting a transmit (TX) signal having a TX center frequency in a selected subchannel; and a receiver including: a plurality of local signal generators coupled to said microprocessor; a frequency immunization converter for using data from said microprocessor and said TX center frequency for simultaneously frequency downconverting a desired receive (RX) signal and an undesired TX jamming signal to a desired intermediate frequency (IF) signal at an IF frequency and a residual jamming signal at near to zero frequency, respectively; an IF receiver coupled to and under control of said microprocessor for processing said IF signal for providing output information representative of information carried on said RX signal.
