摘要 |
A cartesian loop transmitter is disclosed. The disclosed cartesian loop includes various fine and coarse power control circuits that allow power control over a wide range and that allow fine control in very small increments. The disclosed cartesian loop also includes a loop filter which minimizes noise in the loop, a DC nulling circuit, an instability detection circuit, a mask detection circuit, an undervoltage protection circuit, a temperature protection circuit and an automatic phase calibration circuit. |
