The “Uncalibrated, +25 °C” Sideband and Carrier Suppression plots were measured at room temperature, while the “Uncalibrated, over Temperature” Sideband and Carrier Suppression plots represent the worst case uncalibrated suppression levels measured at T= -40 °C, +25 °C, and +85 °C. The “Calibrated, +25 °C” Sideband Suppression data was plotted after a manual adjustment of the I/Q amplitude balance and I/Q phase offset (skew) at +25C, and an LO input power level of + 3 dBm. This adjustment setting was held constant during tests over LO input power level and temperature. The “Calibrated, over Temperature” plots represent the worst case calibrated Sideband Suppression levels at T= -40 °C, +25 °C, and +85 °C. The “Calibrated, +25 °C” Carrier Suppression data was plotted after a manual adjustment of the Ip/In & Qp/Qn DC offsets at +25 °C, and an LO input power level of + 3 dBm. This adjustment setting was held constant during tests over LO input power level and temperature. The “Calibrated, over Temperature” plots represent the worst case Carrier Suppression levels measured at T= -40 °C, +25 °C, and +85 °C.
