DIRECT CONVERSION RECEIVER DEVICE WITH FIRST AND SECOND STAGES AND RELATED METHODS |
| 摘要 |
A direct conversion receiver device may receive I and Q signals. The direct conversion receiver device may include a blind IQ balance circuit configured to balance the I and Q signals without a pilot signal, and a mixer coupled to the blind IQ balance circuit and configured to generate I and Q baseband signals using an operational frequency, the operational frequency being based upon bandwidth and modulation of the I and Q signals. The blind IQ balance circuit may include a first stage configured to generate an intermediate amplitude balanced Q signal based upon the I and Q signals, and a second stage coupled to the first stage and configured to generate phased balanced I and Q signals based upon the intermediate amplitude balanced Q signal and the I signal. |

1. A direct conversion receiver device for receiving in-phase (I) and quadrature (Q) signals, the direct conversion receiver device comprising:
a blind IQ balance circuit configured to balance the I and Q signals without a pilot signal comprising
a first stage configured to generate an intermediate amplitude balanced Q signal based upon the I and Q signals, anda second stage coupled to said first stage and configured to generate phased balanced I and Q signals based upon the intermediate amplitude balanced Q signal and the I signal; and a mixer coupled to said blind IQ balance circuit and configured to generate I and Q baseband signals using an operational frequency, the operational frequency being based upon bandwidth and modulation of the I and Q signals. |
