Zusammenfassung: | The utility model discloses a radio frequency transceiving ware chip, it includes two way radiofrequency signal receive channel, each way radiofrequency signal receive channel all partly takes decimation filter, 22 rank partly to take decimation filter, 11 rank including amplifier, first detector, adc, 32 rank connected in order and partly takes decimation filter, FIR decimation filter, passagewayquadrature error correction circuit, receive channel 0 correction circuit and digital receive channel 1. This chip finishes the function that the quasiorthogonal mixing of moulding, ADC sampling, digital filtering extraction and data signal rectified, has really realized the digifax integrated design, solves the unbalanced problem of analog signal quadrature through the quadrature compensation ofcarrying on at the numeric field, not only realizes the zero intermediate frequency sampling but also does not have not balance problem of quadrature. The numeric field carries out signal processinghas congenital advantage, n |
