Zero intermediate frequency to low intermediate frequency receiver architecture |
摘要 |
A transceiver is disclosed having a zero intermediate frequency to low intermediate frequency receiver and a direct upconversion transmitter. Calibrations may be performed to minimize direct current voltage offset and in-phase and quadrature-phase path mismatch after downconversion. Automatic gain control is performed prior to downconversion and after upconversion to minimize the introduction of mismatch.
