RF TRANSMITTER WITH INTERLEAVED IQ MODULATION |
摘要 |
An RF modulator supporting wide-band signals includes IQ modulation by interleaving the in-phase and quadrature signals. The modulator can be implemented using an integrated circuit having a baseband in-phase stage that receives an in-phase analog input signal, a baseband quadrature stage that receives a quadrature analog input signal, and a switching mixer having a plurality of switches. The switching mixer receives in-phase and quadrature signals from the baseband in-phase stage and the baseband quadrature stage. The switching mixer produces a differential signal combining the in-phase and quadrature signals by interleaving the signals over a plurality of phases of a carrier period. |
